Business idea: production of concrete fences. Concrete fence making mold Concrete fence making equipment

A well-maintained private household must have a reliable fence that protects the territory from uninvited guests. Modern plots, country houses and cottages from the side of the street are often decorated with an aesthetic decorative fence made of concrete. A structure of this type is often called a "euro fence", although in Europe it is not widely used. Such a fence can be made and installed independently, and it will cost half as much as the services of specialized companies. A simple technology for manufacturing panels and columns is available to the home master.

What is important to know about the installation of decorative concrete fencing?

The associative series of words "fence", "fence" and "fence" draws in memory not the most pleasant pictures. But rough concrete tile panels are a thing of the past, thanks to people who thought of bringing aesthetics to the fencing industry. And now decorative concrete fences are becoming more and more popular. Of course, no one will make a decorative concrete fence for the industrial zone, but courtyards in residential areas are increasingly equipped in the same way as the private sector - with an attractive concrete fence. They surrounded the territory of kindergartens and schools, private enterprises and banks.

Do not rush to buy reinforced concrete panels, you can make them yourself if you stock up on forms, tools and patience. To do this, select those types of plates from which the fence should be equipped:

• pillars and supports (reinforced concrete, stone, brick, metal);
• decorative panels (solid, openwork);
• decorative finials for a concrete fence.

The panels are made one-sided (with a pattern in the courtyard or on the street) and with an imprint on both sides. With regard to ready-made blocks produced in an industrial way, they can be made lighter and more openwork. It depends on the height of the fence, the functionality and desire of the owners. Someone wants to isolate themselves from the outside world with a high solid fence. Others like a light openwork fence - landscape design is visible through its pattern. Carved shaped blocks are one and a half times lighter than solid ones, and much less consumables are used.

No matter how beautiful the future decorative fence is, there is nothing complicated in its construction. Together with an assistant, it is easy to cast slabs of various configurations in a week, using ready-made molds - for the base, filling and tops. Additional whitewashing or coating with facade paint will help to give individuality to such a fence. A few good examples are a decorative concrete fence, photo:

For the installation of finished fencing slabs, a team of 3-4 people is invited to prepare holes for the supports. According to the markup, they will prepare a line for installing columns, after which, together with an assistant, it is easy to install a decorative concrete fence. A hole drill or other suitable technique will help to make holes on your own. Large monolithic sections are lifted by a crane.

Advantages and disadvantages of a concrete fence

Many paid attention to how the aesthetic concrete fence and its decorative panels compare favorably with other fences. And those who installed it managed to appreciate this durable fence for ennobling the site, especially when its panels are with a double-sided pattern.

Tip: There is no point in the laborious manufacture of a decorative concrete fence, when part of it goes to the economic part of the yard, goes along a blank wall or tall bushes. On this segment, limit yourself to ordinary panels without a pattern, while maintaining the dimensions and the distance between the columns. On the site along the smooth panels, in order to improve the appearance of the fence, plant decorative climbing plants or hang ampelous flower forms in flowerpots - photo:

The main advantages regarding stone, wooden, metal fences and a transparent fence made of a chain-link mesh:

• relatively low cost relative to other capital fences with high quality;
• it is possible to do all stages of the process with your own hands;
• quick installation, thanks to the prefabricated structure;
• strength of reinforced concrete structures;
• reliable and stable fencing;
• fire resistance, frost resistance and high resistance to adverse weather factors;
• long service life (about 50 years);
• the possibility of replacing damaged sections (for example, if a car drives into the wall in an accident) without a radical repair of the entire fence chain;
• sufficient choice of design solutions;
• a budget update or a change in the appearance of the fence by replacing the top sections or re-painting.

The only drawback is that a solid decorative concrete fence does not let in the sun's rays, slowing down the development of flowers and plants. So that the site in the place of a high blank wall is not empty, tall trees or shade-tolerant climbing plants are planted. In Britain, such fences are ennobled with evergreen ivy. As an option, in this place of the garden to equip a platform for barbecue or barbecue.

Attention: If thermophilic and sunlight-demanding plants should grow along the concrete fence, then choose a low openwork option, ensuring the full development of the seedlings. Behind a high solid fence, light-loving sprouts wither away.

An important advantage is changing the height of the concrete eurofence without compromising the appearance. Can choose:

• one decorative section - with low partitions inside the site;
• two sections - for a low wall, so that animals on the back side of the site do not wander into the site;
• three sections - standard equipment, where the lower solid, middle openwork and elegant upper sections of intricate shape are harmoniously combined;
• four sections - heavy fences where a foundation may be needed, used for a high decorative concrete fence, photo:

The cost of prefabricated concrete fencing: calculation features

Do-it-yourself decorative concrete fences cost almost half as much as orders from a profile company. But at the same time, it is difficult to name the exact amount of what the Eurofence on the site costs. It is important to consider:

1. The final cost is less affected by the difference in individual panels from the manufacturer and the complexity of the patterned finish, as well as the equipment and installation method. The exact price tags for finished panels are specified by region or selected from catalogs. Do not forget about the columns to fix the sections, which should be more than one, and the tops on the columns. From the total number of sections subtract the gap for the gate and the gate.

Attention: If it is unprofitable to install a fence around the entire perimeter of the site, then they are limited to the facade facing the street. Along the rest of the length, columns are installed and a chain-link is pulled, which will stand for more than one year.

2. You can save a lot on installing a concrete fence made of decorative blocks. If the minimum price of a running meter of an eurofence is from 1000 rubles, then installation services are priced at half. Installing a heavy solid fence with a foundation costs about the same as the fence itself. The cost of self-installation of the fence depends on how heavy the concrete sections are - whether there will be a need for lifting equipment. An important factor is excavation for columns that are being dug:

• shovels by hand;
• with the help of technology;
• garden hole drill or other device.

3. The cost per linear meter depends on its height (the number of decorative panels for the fence in one section between the columns). Usually choose fences in 3 sections with the end point of the arch above eye level.

4. In case of self-manufacturing of decorative concrete fence posts, finials and stacking blocks, their cost is affected by:

• type of reinforcement of sections and the cost of metal inside them;
• the cost of molds for casting openwork blocks and formwork for solid sections;
• the cost of the components for the concrete solution (river sand can sometimes be washed and sifted on its own);
• complexity of the relief on the site;
• the total number of elements.

The costs for the forms for solid and openwork sections and columns will pay off if, after the successful manufacture of a decorative concrete fence with your own hands, you start a mini-production. Surely, such a fence will be a little cheaper by someone in demand among friends or relatives. Used forms can also be purchased from ads and sold.

Tip: If you are not confident in your abilities, but you want to have an exclusive decorative fence on your site, develop your own version of the sections and let specialists make them to order. But a one-time work on an individual design, not stamping, will cost more.

Forms for decorative concrete fence

Forms for a decorative eurofence are easiest to buy ready-made, since there are many enterprises that specialize in their development and production. Solid sections are cast using formwork. Matrices for curly sections are also made independently - video at the end of the article.

Finished forms after purchase do not need additional processing. It is not difficult to choose a print for the most liked drawings - with such a large assortment. To date, about 30 matrix design options have been developed for casting sections, decorative elements and posts.

Forms and panels that seal them are produced from ABS plastic with imitation of a different pattern, for example:

• wooden plank;
• vine;
• muslim side;
• chip;
• rope;
• Kremlin wall;
• convex brickwork;
• concave masonry;
• ancient mosaic;
• rocky mountain;
• Chinese Wall;
• lock bars, etc.

There are also composite options for sections, where different materials are combined. The designers have also developed sections with jigsaw puzzle connection. The most common types of panels:

• unilateral and bilateral;
• solid (monolithic) lower smooth or textured (under wild stone, brickwork, cobblestone, tile, wood bark);
• openwork (lattice, patterned, columnar) middle and combined (transitional);
• top arches.

Making panels with your own hands using ready-made forms

For self-production you will need:

• ready-made forms for a decorative fence made of concrete and for finials;
• formwork for stamping pillars;
• vibrating table for compaction of the mixture;
• small concrete mixer;
• apparatus for welding the reinforcing frame;
• pallets or shields for drying ideas.

Tip: Buy ready-made forms, and there will be no problems with manufacturing. This is the best option for quick assembly of a standard design fence. The directory contains the following forms:

• from silicone;
• from plastic;
• from polyurethane;
• fiberglass;
• from light metal.

There is a desire to do something exclusive - make matrices for the blocks yourself. There are several technologies for self-issuing forms, a good example is in the videos at the end of the article.

For the manufacture of panels and decorative finials on a concrete fence, consumables will be needed:

• river sand;
• small-sized crushed stone;
• metal rod for reinforcement;
• high viscosity cement;
• plasticizers (to obtain a solution of the desired texture);
• frost-resistant additives;
• ready forms.

The basis of the mixture is an ordinary cement mortar, where crushed stone is added for stabilization. If there is a desire, the form can be sprinkled with granite chips, then on the front side it will have a more interesting texture, sparkling with crystals in the sun. When forming thin concrete products, one cannot do without a frame, and metal trimmings and rods that are connected by welding are suitable for reinforcement.

Tops or caps can be rounded or faceted, but you can do without them. Columns for fixing panels are cast using formwork. It is imperative to provide recesses in them, which are designed to hold the fence blocks.

Some of the materials used to make precast molds give some adhesion, making the finished product difficult to remove. To do this, you will need a stripping lubricant or a special liquid sprayed from an aerosol.

When the forms are prepared, the components for the mixture are poured into the concrete mixer in proportion - 2 parts of sand, 3 parts of fine gravel, 1 part of cement and water. In order for this base to be better mixed, it is better to add crushed stone and a plasticizer to the cement mixture, about half a percent of the total volume. The water repellent will increase the frost resistance of the blocks and water resistance, which is especially necessary for the lower blocks.

The vibrating table gives the best results - the blocks are uniform, without air inclusions. Do not forget to put a reinforcing frame on the mortar, which will drown itself during vibration.

Attention: If turning angles are to be made, then it is necessary to cast posts with grooves at an angle of 90°.

The base is poured in an open and closed way, but it is laborious for home conditions. It is used for casting double-sided decorative panels. Open pouring is much easier, it allows you to see preliminary results and eliminate air inclusions. To represent the entire casting process, watch the master class on the video:

Installing a decorative fence

After all the elements of the future eurofence have been prepared, it remains only to prepare the holes for the poles, marked out along a stretched rope. Places of fixing points for supports are marked with pegs. Pits are dug at an equal distance, while taking into account the shape of the column, into the grooves of which the panels will enter. It is important to accurately observe all the calculations so that you do not have to redo it. It is very convenient to dig holes with the help of mechanical devices.

To dig in the pillars, crushed stone and sand are needed for compaction, and the holes are poured on top with concrete for hardening. Be sure to check the verticality of the installation with a plumb line before the mortar sets. A foundation is laid under high heavy fences, but you can limit yourself to supports dug in the center.

The final stage is the laying of concrete slabs between the pillars. It is important to consider how these plates will rise and fall into the grooves. If the panels are light openwork, then two people are enough, and monolithic heavy blocks are understood by a crane. Upon completion of the work, the horizontals and verticals of the structure are checked, and all defects are eliminated. The finished fence can be whitewashed or painted with facade paint on concrete after priming. It is easier to work with a spray gun, but if you need to paint over individual parts, then this is done with a brush and roller - over smooth parts.

Today, people have become very scrupulous about the issue of registration of their property. And in this regard, the demand for various original elements of decor and design is increasing every day.

Owners of various cottages, townhouses and just homeowners face some problems of individual design. The fact is that most projects of such buildings are created according to a certain template. Therefore, it is very difficult to stand out in any way among other similar buildings.

Decorative fences made of concrete come to the aid of modern homeowners. These structures will not only help to enclose your property, but also give the site an individuality. And since the competition in this business is minimal, you can make good money on this. It is the production of fences that we will discuss in this article.

Demand

In fact, manufacturers of forged gratings and similar products are in great competition. But before the iron structure, concrete fences have at least three advantages: strength, lower cost, ease of operation.

After all, forged products must be constantly painted, covered with protective enamel (from rust), and in extreme cases replaced due to various types of deformation.

Concrete decorative fences are more unpretentious in use and more durable in design. The number of low-rise buildings is constantly increasing (at least in Russia). But, to great surprise, the number of companies that provide services for the construction of concrete fences remains relatively small.

And those firms that are engaged in this business are working in a direction that is very different from the topic of this article. From all this, we can conclude that the market lacks narrowly focused manufacturers of decorative concrete fences.

Business Features

Many people are surprised by one very strange fact, namely, why does the production of fences not attract large enterprises? It is impossible to answer this question unambiguously. Perhaps the owners of large companies do not see prospects in this business, or the vast majority of firms are simply not satisfied with this profile of work.

In any case, the absence of the dominance of individual enterprises is even for the better. Due to the lack of large companies in this business, customers have to turn to small manufacturers who do all the work by hand. And, as you know, the cost of such firms is clearly overpriced. To establish a rapid rise, it is necessary to produce a product in large quantities, thereby reducing the cost of one unit of production. We must not, of course, forget about the quality of buildings (more on that later).

Individuality and wholesale sales

One of the most difficult moments in the production of a decorative fence is the combination of mass production and the individual characteristics of each product. It is necessary to create the illusion of a personal approach to each client.

It is worth noting that most of them will be middle-class people who are trying to stand out. As you can see, there are enough difficulties in this business, so you need to carefully consider every step you take. Everything that was before, concerned only the general aspects of this case. Now it is worth talking about production technology and special equipment.

Production

During the production of any product, one of the most important points is the careful preparation of raw materials. The final product will directly depend on their quality. The next most important factor is the correct selection of the necessary equipment. This list includes molds, molding equipment, vibrating screen, and so on. All production of fences can be divided into three main stages, which we will discuss further.

First stage

The main constituents of concrete are cement and sand. It is with these elements that production begins. The first step is sifting sand and cement. This is done using special equipment called a vibrating sieve. It is equipped with an electric drive, and the materials themselves pass through cells no larger than 5 mm in size.

All equipment for the production of concrete fences of this type must be present in several copies. A single production (on order) requires no more than 2 such machines. If you are counting on wholesale, then you will need 3-4 (or maybe more) vibrating sieves. The cost of one such machine depends on the capacity and the amount of available resources. The average price is $500.

Second phase

The second stage of work consists in mixing the finished mixture of concrete. It is inefficient to perform this process manually, so it is necessary to use automated tools. For this work, so-called concrete mixers or, as they are called in another way, concrete mixers are used.

In the world market of construction equipment there is a huge selection of different manufacturers of this device. Here we will not discuss all types of concrete mixers, but only single out only two large categories: gravity and forced. The first type of concrete mixers is distinguished by its low price. The cost ranges from 350 to 2000 dollars. Also, many of these devices are portable and do not require industrial voltage for operation.

The exception is the most powerful gravitational devices. Another category of concrete mixers (forced) are much more expensive. Naturally, along with the price, all other characteristics also increase: voltage consumption and performance. Also, most forced mixers are stationary, and in some cases an additional light foundation is required. Non-portable concrete mixers are often equipped with a lift called a skip.

Concrete fence production will be greatly accelerated with this addition. The skip allows you to pour the concrete mixture even at a height. The lift also automates the process of loading materials, which frees up one workforce (otherwise it will take 1 person to carry out this operation). The control system consists of a guide winch and a movable hopper.

Third stage

The production process of fences is completed by pouring the finished mixture into a pre-prepared form. It is at this stage that conventional building materials begin to take on a familiar form.

The form for the concrete fence itself must be made without any flaws, including no welds and other types of defects.

If these conditions are not met, then a low-quality product may ultimately result. This can ruin all the work done earlier. The form for a concrete fence is of two types: deaf and openwork. The price of this equipment is approximately $350. When starting a concrete fence business from scratch, molds are practically the most costly element.

Imagine how many types of this equipment you will need to buy to increase the variety of finished tiles. Medium-sized companies should have at least 50 types of molds in stock, plus each type should be in several copies (to speed up the production process).

Business expansion

Every businessman should strive to increase production. In this case, you can offer various additional services to your customers. For example, design (which will match the general appearance of the building), installation (and dismantling of old fences).

Further expansion will depend only on you. You may want to bring your business closer to the middle class by adding various small decor elements. Or you will serve large companies by making only unique concrete decorative fences. In any case, the scale of your business depends only on you.

Conclusion

As a conclusion, it is worth mentioning the search for employees. This case needs to be approached with some imagination. In addition to the workers who will make the fences themselves, you need to find a creative designer. In the process of business development, you may need to additionally purchase (or make your own) various decorative elements: borders, fountains, urns, flower girls. The production of concrete fences is one of those lines of business that can turn into a gold mine with the right approach.

Concrete fence for fencing the local area is not only reliable protection, but also an additional decoration of the architecture of the house. Today, concrete fences are considered one of the most reliable and durable, and you can make them yourself.

What types of concrete fences exist

First of all, they are distinguished by purpose and design, secondly - by manufacturing and installation technology.

The functional task of the fence is to enclose the territory, which also contains a decorative meaning. So, next to a wooden log house, this fence will look out of place, but the architecture of a stone building will be in harmony with concrete panels or bricks.

Nowadays, fences are built not only from flat-shaped ready-made concrete panels - they can be made independently using various forms. In addition, decorative fencing can imitate natural material, have different colors and a certain style.

Possible options in the photo

A stone structure on a solid foundation will protect the local area from prying eyes The hollowness of concrete blocks allows the use of a large number of elements due to their low weight. The simplest of the fences - monolithic with one decorative side Embossed inlays are a refreshing highlight A double-sided fence can be easily used on a personal plot The contrast is created by the support pillars of a dark color, echoing the color of the roof of the house. Both the design itself and the finish are expensive, but justify their service life.

Types of fences

These include:

1. Monolithic.
2. Typesetting.
3. Decorative.

Table: advantages and disadvantages of concrete fences

Monolithic fences are used, for the most part, by large enterprises, institutions and even guarded parking lots - organizations for which the protective function of the fence is primarily important. Such fences have a rough external texture and are panel. They cannot be stacked on top of each other, as a constructor, because the panels are heavy. A prerequisite is the construction of a solid foundation.

Recently, monolithic reinforced concrete slabs have been installed on the plots, thanks to which the fence is called independent. A characteristic feature is the obligatory wide horizontal base of the plates for installation; in some cases, independent fences can be installed with spikes on the "glass".

Type-setting is called a fence, consisting of several plates. Type-setting plates have both a different texture and a decorative side, and one of the parts of the sections may differ from the other - as a rule, these are the upper rows of the fence.

In one section, there can be up to four assembly panels installed in the grooves. For a type-setting concrete fence, it is also necessary to construct supports - special pillars to which the sections will be attached.

When installing a stacked type of fence, it is necessary to accurately calculate the step between the supports, as well as firmly fix them.

Most owners of private houses use concrete europanels instead of conventional panels, which are lighter and more convenient to install. The most common size of the europanel is 2.0x0.5x0.12 m. In addition, typesetting panels are often produced double-sided - having the same surface appearance on both sides.

Decorative fences include panels erected from separate sections.

Decorative fences can imitate textures such as:

• wood;
• brick;
• granite or marble;
• cobblestone and raw stone;
• metal forging.

How to make a concrete fence with your own hands

Fences can be installed from standard panels purchased on the construction market. And you can make it yourself - "for yourself." Do-it-yourself construction of a protective structure will be an advantage when the owner wants to see a non-standard design on the site that is in harmony with the overall architecture of the house and the local area.

Preparatory work

First you need to choose the material for mixing the solution. For this you will need:

1. Cement M400 or M500.
2. Crushed stone of small fractions - 19–20 mm.
3. The sand is coarse grained.
4. Water.

By mixing them in a certain proportion, a solution is obtained that must be used immediately - otherwise it will harden. The time to set the strength of the structure is four weeks.

It should be remembered that the more sand in the solution, the lower the strength of the concrete will be.

Table: concrete mortar recipe

For the manufacture of concrete blocks, a little plasticizer is added to the solution - it will give greater plasticity to the raw material and allow you to create the required shape for the blocks. Water is added to the solution until the texture of viscous thick sour cream.

The solution can be kneaded in a large trough, but the presence of a concrete mixer will speed up the process.

When working with a concrete mixer, crushed stone is first loaded into it, filled with a small amount of water - so that the cement does not stick to the blades of the inner drum, and only then - cement and sand.

Preparation of tools and forms

The mortar mixture is already being mixed in a concrete mixer, now it remains to prepare the tools for work:

• spatula, level;
• forms for solution;
• steel reinforcement (section 4 mm for the fence and 8 mm for the pillars).

If possible, then at the time of the fence at the construction site, it is advisable to install a vibrating table - for compacting concrete forms. The molds themselves are sold in hardware stores and are rubber, polypropylene, plastic and fiberglass.

Calculation of the number of slabs and concrete for the construction of a fence

If you have already decided on the type, then you can proceed to the manufacture of plates. For an ordinary flat fence, you will need a removable formwork and mortar. The amount of volume for one plate can be calculated based on the formula:

V \u003d L x H x B, m 3, where V is the volume, m 3; L - length, m; H - height, m; B - width, m.

Thus, for one plate measuring 1.6x1.5x0.15 m, the volume of the solution will be 0.36 m 3. The width of one slab of a homemade fence must be at least 150 mm.

The number of plates will depend on the perimeter of the fenced area. It should be remembered that the total length of the fence includes the size of the supporting pillars, the cross section of which is 300x300 mm.

Again, for an area of ​​​​36 m 2 (6.0x6.0 m), 12 slabs will be needed:

N \u003d P / L \u003d (2 x (a + b) - 0.3x16) / 1.6, pcs, where P is the perimeter of the fenced area, m; a and b - sides, m; 0.3 - length of one column, m; L - length of one plate, m.

The number of pillars for the entire perimeter is 16 pcs, obtained from the calculation (a-3xL) / s, where a is the side of the site = 6.0 m; s - 0.3m - column length, m.

There are 4 posts on one side of the fence, therefore, a total of 16 pcs should be supplied.

The total volume of the solution on the plates will be at least 0.36 m 3 x 12 pcs = 4.32 m 3.

On the base for the slabs (although it is preferable to arrange a strip foundation) it will take a little less: with dimensions of 1.6x0.5x0.3 m, the volume of the solution is V = 0.24m 3. For slabs in the amount of 12 pieces, concrete will be spent V = 0.24x12 = 2.88m 3.

The total total volume of the concrete solution will be 4.32 + 2.88 = 7.2 m 3

The width of the foundation for the fence should be twice the width of the slab.

If the choice fell on a concrete fence from ready-made forms, then everything is simpler. You just need to follow the instructions for making the amount of solution for a particular form.

Device from ready-made forms

• The concrete mixture is loaded into the concrete mixer.

• A pouring mold is placed on a flat surface, lubricated with oil or a special compound, which prevents the solidified solution from sticking.
• Reinforcement is placed in the form - for the strength of concrete adhesion.

• After laying the reinforcement, you can pour the solution. After filling the form to the brim, the concrete should be leveled with a spatula.

• After drying, the finished product is removed and placed until completely dry - under a canopy. After making the required number of molds, they can be installed on the foundation, fastening the sections together using support pillars.

Device using formwork

With an independent fence device without using a form, the whole process boils down to the fact that instead of ready-made forms, it will be necessary to arrange a removable formwork and foundation.

The foundation for the fence should be wider than the main structure.

This is done in the following way.

First, a solid (preferably strip) foundation is constructed for the future fence, for which a ditch is dug with the required width, a sand cushion is arranged there with a layer thickness of 20–25 cm.

The layer is then poured with concrete mortar and left until it reaches its branded strength - usually for a month. Periodically, it is desirable to moisten the concrete structure with water for greater hardening.

While the foundation is gaining its strength, you can prepare the material for removable formwork - panels, boards and supports. The formwork is set to the width of the planned fence, fixing it on both outer sides.

The fence can be built both separately from a standing house, and for a fence that is closely adjacent to the house

Do not forget about the reinforcement of the structure!

After preparation, the concrete mortar is poured into a self-made form from the formwork to an initial layer height of 20–25 cm, then it is carefully rammed and more mortar is added to the same layer height. The number of layers can be different - it is important that the fence is poured into the formwork on the same day, otherwise even a newly built structure may crack.

The height of the fence can be arbitrary - it will depend on the height of the formwork structure. The poured solution is allowed to settle for at least a day, after which the formwork is removed and transferred to another area.

This construction system is the simplest. The complexity of the work lies in the preparation of the mortar and the arrangement of the formwork structure.

Finishing the finished building

The fence has been delivered and requires the final touch - a decorative finish, which includes:

• painting;
• decorative plaster;
• brick and clinker tiles;
• laying decorative and natural stone.

The most affordable and easiest type of finish is painting the fence in the color you like. True, for this you will have to prepare the surface - sand it, repair possible cracks, level and prime.

Concrete paint manufacturers guarantee an 8-year service life, which is pretty good and inexpensive for a concrete fence. Another advantage of the paint is that it can be used not only on a flat, but also on a relief surface - where the fences are type-setting, with a decorative surface.

It is necessary to paint the surface - so that the fence lasts as long as possible, is protected from moisture, and blends harmoniously with the overall architecture of the house.

The choice of paints today is great, but you should choose from those that have frost and moisture resistance, resistance to temperature changes and ultraviolet radiation. All requirements are met by ordinary facade paint - acrylic, latex, silicone. An important condition: the paint must have a low vapor permeability coefficient.

The amount of paint is purchased at the rate of 1:300 - 300 ml of paint will be required per 1 m 2. However, the final volume will depend on the type of surface - the more embossed, the more paint will be needed.

As for color schemes, the most successful are those close to natural - beige, green, brown, pale blue or gray. The choice of these shades will be in harmony with the planted plants, shading their natural beauty.

Variegated colors for painting the fence are unacceptable - a couple of shades are enough. If the fence is embossed, then individual elements can be highlighted using a contrasting color or the same shade as the fence itself, only a few tones darker.

In addition, properly applied paint can imitate wood or sandstone - for this, a foam rubber sponge is used, dipping it into paint of different colors - dark and light. The paint is applied to a pre-primed surface - in order for the layers to better grasp each other.

If you want some frills, then you can use decorative plaster. As a rule, high-quality material is selected, and in this case, Venetian plaster can even be used - it is of higher quality, lasts longer, and is not afraid of dampness and temperature changes. It can imitate marble - then the surface is smooth.

You can also use marble or granular chips.

The disadvantages include the complexity of the process - for example, the same Venetian plaster will have to be applied at least 5 times, and for better adhesion to the concrete surface, manufacturers advise applying up to 12 layers.

The third type of finish is brick or clinker tiles. Here the complexity of the process lies in the ideal alignment of the main surface - otherwise, the finish will not adhere well to concrete and will soon fall off. Therefore, relief panels, typesetting fences and sections with a decorative pattern cannot be used.

Stone trim is the most expensive type of fence cladding, but it is the most durable. Before laying, the surface should be thoroughly cleaned, sanded and primed, as well as reinforced - so that the material lasts as long as possible.

Of the advantages of finishing with stone, one can note the luxurious appearance and strength of the fence, of the minuses - the cost and laboriousness of the work, a large load on the foundation. Therefore, if it is planned to install a concrete fence with subsequent stone finishing, the type of foundation will have to be selected at the stage of preparatory work.

The construction of a concrete fence for fencing a local area is a laborious process, but the result is worth it: having durability and strength, such a structure will last much longer than a fence made of wood or corrugated board, and will require less costs in the preparation of materials and annual maintenance.

Even with the current huge selection of materials, a decorative concrete fence is one of the most sought-after and popular types of modern fences. It will not only provide reliable protection to the site, but will also become its aesthetic decoration. It is also captivating that such a fence will last a very long time without losing its quality characteristics, and you can cope with its manufacture with your own hands.

Advantages of concrete fences, features and disadvantages

Before installing a concrete fence, you should familiarize yourself with its advantages and disadvantages. The advantages of a concrete fence are quite significant:

1. Long service life (up to 50 years).
2. Wear resistance.
3. All sorts of textures and colors.
4. Easy installation.
5. Fire safety and frost resistance.
6. Versatility - can be used for sites of any type and size.
7. Noise shielding.
8. impenetrability.

There are also cons:

1. A fence made of concrete needs regular maintenance - treatment and prevention of damage.
2. Dimensions of the structure due to design features are limited.
3. Big weight.
4. Bad shock resistance.
5. To install monolithic panels, a foundation is required.
6. Not cheap price.
7. The "concrete box" effect.

Types of concrete fences

1. Monolithic. These are heavy reinforced concrete panels, for the installation of which a crane is used. They need a strong foundation - tape or columnar. This is the most durable version of the fence, which is most often used in industry - to protect the territories of warehouses, workshops and enterprises.
2. Typesetting. Due to the small size and weight of the sections, such fences are very popular in the private sector. The sections are inserted into the grooves of the supporting pillars, so two or three people can easily handle the installation. The fence can be made both deaf and openwork, or combined from different types of sections.
3. Bilateral. They look the same - both from the outside and from the inside.
4. Unilateral. A cheaper option that has a pattern or texture on only one side.

If we talk about factory products, then the most popular are concrete fences (or eurofences), which are mounted from blocks or horizontal sections. Their width, as a rule, is 2 meters, and their height is from 0.3 to 0.5 meters. Blocks weigh from 25 to 70 kilograms. Such structures are easily transported and cost less than their monolithic counterparts. The composition of the eurofence is cement (grade 500), fine gravel, sand, reinforcement (steel reinforcement and polypropylene fiber) and superplasticizer. It can be of any color, and lined with the desired material - marble, granite or ceramics.

Fences come in a variety of types.

They also produce frost-resistant cinder blocks. Expanded clay or pebbles are added to the concrete mix for these slabs.

Calculation of the number of concrete sections

The manufacture of concrete fences begins with the calculation of the number of slabs that are required to fence the site along its entire perimeter. To do this, you need to mark the territory. At the corners of the perimeter of the site, pegs are hammered, between which a cord is pulled. This will be the line of the future fence. It is important to note those places where the installation of plates will not be possible in order to move the fence forward or backward.

The standard size of a europlate is 2 m wide and 0.5 m high. However, taking into account tolerances and all kinds of gaps, it is customary to take a length of 2.06 m as a basis.

The recommended fence height is 2 meters. In this case, the site will be hidden from prying eyes. When calculating, it is also necessary to take into account the support pillars, the cross section of which is 15x15 cm. Thus, when installing 10 plates 2.06 m long, the length of the fence will be 20.75 m, taking into account the first and last support pillar.

Territory marking

Tools for the job

1. Concrete mixer or other mixing container.
2. Trowel, shovel, pointed rod.
3. Section form.
4. Armature (wire).
5. Level.
6. materials for the mixture.
7. Vibrating table.
8. Composition for lubrication of molds.

The process of manufacturing and installing a concrete fence is not too laborious, but it will take time and several pairs of working hands. If you decide to cast the plates with your own hands, then the first step is to decide on the proportion of the future solution, its composition and the shape of the product. The quality of the components is also important: for example, the use of untreated sand instead of prepared sand can contribute to the deformation of the slabs under the influence of the external environment after a few years.

Solutions for the construction of a concrete fence

Main ingredients for the mixture:

• Cement (grade not lower than 400).
• Peeled river sand, size 1.3–3.5 mm.
• Gravel, crushed stone washed.
• Water.

Standard Mortar for Concrete Blocks

• Crushed stone or expanded clay - 1 part.
• Sand - 3 parts.
• Cement - 1 part.
• Plasticizer - according to the instructions.
• Water (until the mixture becomes the consistency of thick sour cream).

foundation mortar

• Crushed stone - 2 parts.
• Cement - 1 part.
• Sand - 2 parts.
• Water (to optimal density).

For ease of pouring concrete, you can use ready-made forms. They are:

1. Polypropylene.
2. Rubber.
3. Plastic.
4. Fiberglass.

Step-by-step process of pouring the concrete mixture into the finished form

Step 1. Before pouring the panels into the mold, you need to prepare a reinforcing frame. For it, reinforcement or metal wire with a diameter of 4 to 6 mm is used. The material is laid in a grid, with a step of 10 by 10 cm, and welded.

Rebar laying scheme

Step 2. Preparation of the composition. It is best to mix the mortar in a concrete mixer, but if it is not available, then any bulky plastic container or an old bathtub will do. All components are poured into it, and then water is gradually added. In this case, the density of the solution is regulated. The mixture is thoroughly stirred until smooth (no more than 10 minutes), and poured into a pre-prepared form, pre-installed on a wooden shield or an old door. The base is level.

Filling the form with concrete mix

Step 3. The form must be lubricated with a composition of diesel fuel and used engine oil.

Step 4. Pour half of the solution into the mold and wait for a while. Next, we lay the reinforcing mesh and distribute the rest of the mixture on top.

Step 5. We knock on a wooden shield with a hammer so that the concrete, compacted, highlights the cement milk on the surface. This simulates vibrocompression, during which the concrete completely fills the form. You should also pierce the solution with a pointed rod to release air.

Step 6. We smooth the surface with a spatula and close the mold with a film until the mixture has completely solidified. The process takes one to three days. Concrete matures longer - up to 30 days. Only after their expiration, the panels can be installed. Finishing work - priming and painting, is carried out 6 months after the manufacture of the panels.

Installation of concrete fence posts

The service life of the fence directly depends on properly installed supports. They take on the entire load, therefore, the higher the concrete fence, the more powerful its supports should be. Fencing posts can be stacked or solid. But in both options, grooves are provided for installing concrete sections.

Finished concrete fence posts

Mounting on solid poles

There are two ways to mount on monolithic poles.

The first is that all the pillars are concreted into the marked places at once, and after the concrete has hardened, the slabs are installed in the grooves (through the top). The downside is that it is difficult to implement without special tools, and also that this method does not tolerate markup errors. It will be impossible to eliminate the error without a complete rework.

The second method is more convenient. Only the first pillar is concreted, and the second is not rigidly fixed. Further, all the plates are put on the pillars, and then the second pillar is tightly put on them and fixed with the help of broken bricks. The structure is leveled and the installation continues further. The column is poured with cement after the installation of all plates.

Step 1. Markup. The strength of the fence depends on the accuracy of the installation - if the posts are too close, the panel will not fit into the grooves, and if it is too far away, then the section will fall out. Therefore, it is important to drive the pegs in correctly.

Drilling wells for supports

Step 2. Drilling wells under the pillars for a third of the length of the pillar.

Pillar installation scheme

Step 3 Installing the support post. It is installed in a pit and covered with rubble by 15 cm. After that, its verticality is checked by a level, and the pillar is poured with concrete. Extreme supports are installed and a twine is stretched between them. The remaining pillars are already equal to it.

Step 4. Installation of sections in the grooves of the pillars. Bonding them with a solution to each other. Some craftsmen do not advise completely closing the gaps, since the pillars can “play” in winter and they need compensation gaps.

Mounting a fence on stacked poles: step by step instructions

Stacking poles are hollow blocks assembled around a steel pipe or cast onto a reinforcing cage. Block cavities are usually filled with concrete.

Hollow block for post

This technology is good because it does not require a foundation for the entire fence - it is needed only for pillars.

Step 1. Preparation of holes 1 or 1.2 m deep and 20 cm wide.

Step 2. Backfilling crushed stone at the bottom of the pit.

Step 3. Installation of a pipe or reinforcement so that it comes out 40 cm from the ground, and its subsequent concreting.

Armature location

Step 4. After preparing the foundation, the column is assembled. The first block is put on each post along the entire length of the fence. The block is positioned so that the metal core is in the middle.

Step 5. The first row of panels is put on the recesses of the pillars and poured with concrete. Concrete should be liquid, and the ratio of sand and cement should be 1 to 4, or even 1 to 5.

Blocks are put on reinforcement and concreted

Step 6. Next, the second row is installed, until the height of the fence reaches 1.5 m. After that, soil is added to the lower section of the fence. It is not necessary to dig deep into the ground - otherwise, in frost, the earth will begin to break the fence.

Step 7. The installation of the blocks continues until the installation of the top decorative panel.

Step 8. Installing caps on poles.

Painting and decorating a concrete fence

In order for a concrete fence to last as long as possible, it must be properly looked after. There are several reasons for this.

1. Technical. Painting is needed in order to protect concrete from external influences and extend the life of the fence.
2. Psychological. By itself, concrete is nondescript, and coloring will make it brighter and more pleasant to perceive.
3. Decorative. In order for the fence to harmonize with the color of the room, an appropriate shade is selected.

What paint is suitable

Higher requirements are imposed on the paint for concrete fencing. She must be:

• moisture resistant;
• frost-resistant;
• resistant to temperature extremes and sunlight.

These requirements are fully met by facade paint of any type - both matte and glossy. If the fence is located on the sunny side, then it is better to choose a matte paint, because the glossy one will glare a lot. It is preferable that the paint be water-based. For example, acrylic, acrylate, silicone or latex. The main thing is that it has a low level of vapor permeability and a sufficient content of acrylates.

When calculating the amount of paint, it must be borne in mind that the more embossed the surface of the fence, the more material will be needed. On average, 1 m² will require about 300 ml of paint.

Various decor of concrete fences

Color solutions

The most preferred colors from an environmental point of view are brown, green, grey, blue or beige. These natural shades will harmonize and set off flowering plants and green spaces. Do not make the fence too colorful and multi-colored - a combination of two or three shades is enough. Texture elements are highlighted using white, gray or dark colors.

Using paint, you can imitate any surface - for example, sandstone or wood. To paint under sandstone, you must first apply light brown paint, and then dark brown (foam sponge).

Paint application technology

It is not recommended to paint a new fence immediately, as it must shrink. Six months later, you can start finishing work. The principle of staining is the same for both new and old concrete fences. First, preparatory activities are carried out. They include:

• Cleaning the surface of the fence from dust and dirt;
• Surface priming and crack bridging.

Priming must be carried out before painting the fence - it will provide better adhesion of the paint to the surface of the concrete, and get rid of dust and dirt.

1. It is better to paint a porous concrete fence with a spray gun or other professional equipment.
2. If the old fence was restored, you need to wait until the putty materials have completely dried. Irregularities are cleaned with a mesh or sandpaper.
3. Paint the fence in two layers.
4. The primer dries for a day, so you can not immediately paint the primed surface.
5. The second coat of paint is applied after 24 hours.
6. At high humidity and low temperature (below +5 °C), painting is not carried out.

Having studied the process of making a concrete fence, you can try to make it yourself. As a result, you will appreciate the cost savings and great satisfaction with the work done. A handmade fence is a unique product that will last for many years.

Attachments: from 2,000,000 rubles

Payback: from 24 months

Owners of their own houses, companies owning their own buildings, always enclose a private area. It's about calmness and a sense of security from prying eyes. One of the best fencing options is decorative concrete fences.

business concept

A huge part of the buildings is being built according to template projects, so they look the same. Concrete fences are a way to stand out, to give the object its own style and personality. In addition, this is a good alternative to forged gratings: concrete is cheaper and does not need additional painting from plaque and rust.

It is clear that there is a demand for the product and, moreover, it is constantly growing. But the "players" involved in the production of concrete fences can be counted on the fingers. More often, fences are made according to an individual sketch as an addition to another product (plates, blocks, etc.).

Large companies, it is not known why (perhaps they are not attracted to work on a small project), almost do not engage in this type of activity. Buyers have to overpay for concrete fences due to the small number of offers.

With the release of a large number of products, with a relatively low price and good quality, customers will come to you.

Earnings are based on the manufacture of products to order or the implementation of standard designs. Clients are owners of houses with land plots, companies and other persons.

What is required for implementation

First you need to rent or buy equipment:

• vibrating table with 2 electric motors for molding concrete products;
• concrete mixer;
• vibrating sieve to sift components (sand, cement);
• a set of forms;
• trays for drying poured products.

Production begins with the sifting of materials: bases for cement and sand. To do this, they buy a vibrating sieve in advance - the amount depends on the expected amount of work. In mass production, the minimum number of units is 4. To work on an order, 2 pieces are enough.

The next step is concrete mixing. To do this, buy special concrete mixers. Fortunately, the market offers a huge selection of equipment in different price categories.

Next - the last stage - the formation of fence elements, panels. They should be of the highest quality, durable and not deformed with light impact. Deaf forms are cheaper than openwork ones. Buying the latter is a costly business, especially when starting production.

Launch instruction

1. Search and lease of a territory with a total area of ​​at least 300 sq. m - for production, the minimum size of premises - 50 sq. m. It also requires the presence of warehouses, procurement sites. All areas, except for the warehouse, must be heated.
2. Personnel selection. It will take at least 4 people, 2 per shift. Productivity - 100-150 sq. m of fences per shift.
3. Purchase of raw materials: cement grade 500-D0, sand, reinforcing wire and various plasticizers for accelerated hardening of concrete. Also, during installation, you can use facade paint to give color.
4. Direct production (streams or to order).
5. Implementation.

Financial calculations

Approximately (in rubles):

• purchase of materials - 1.7 million;
• monthly rent and wages - 40,000 for the premises, 600-650 0000 - for hired workers;
• equipment - 300,000;
• advertising and promotion - from 50,000.

In total - from 2.5 to 3 million.

You will also need to register yourself as an individual entrepreneur and take care of the availability of an auxiliary financial fund, which, in case of force majeure, can be spent on paying expenses.

To ensure better earnings, you need to establish distribution channels for goods, prepare an effective advertising campaign in advance and conclude several contracts, not only with companies, but also with private traders.

With average volumes of production and sales, the payback of the project is 3 years. Earnings - from 150 to 300 thousand rubles a month.

Business risks and cons

As with all types of production, especially when it comes to working to order, the risk of manufacturing concrete fences is the lack of customers. There is little competition in the market, and such an outcome is unlikely.

In general, this is a good opportunity for your own business. You don't have to be limited to a single line. Today, other concrete products are also gaining popularity - benches, paving stones, etc. A diverse selection of products will ensure a greater influx of customers.
