Bicrost blowtorch. Roofing material bikrost and its advantages. Step-by-step instructions for laying bicrost

Recently, the construction industry offers developers a huge selection of various rolled roofing materials. If not so long ago, only natural bitumen and cardboard-based roofing material were used for these purposes, today not even all professional builders know by heart the existing names of rolled materials and their properties. On the one hand, this significantly improves the quality of roofing, and on the other hand, it makes the choice much more difficult for inexperienced consumers. Moreover, no company indicates the shortcomings of its products, the emphasis is always placed only on the positive properties. In order to better understand what bicrost is, you need to learn a little about the general requirements and properties of all types of soft roofing.

This type of coating is mainly used on flat roofs with a slope of up to 12 °. But in the villages you can find options for covering and gable roofs, most often these are old cottage-type houses or various outbuildings.

Bikrost is manufactured by the very famous TechnoNIKOL corporation, and its specialists pay great attention to the quality of their products. At the same time, not only the current requirements for soft surfaces are taken into account, but also developments are made for the future. The roof is made on the most modern equipment using innovative technologies and materials. Each batch undergoes visual technical control, random laboratory tests are performed.

The Technonikol company produces many varieties of roll coatings for roofing.

All types of bicrost meet the basic operational requirements.

Due to the fact that bikrost can be used both for the internal lining layer and for the top coat, the structure of both types of roofing material is somewhat different.

1. Base. For this purpose, fiberglass is used (a material that is very strong in physical parameters), polyester fiber (the indicators are somewhat worse) or fiberglass (mechanical characteristics are much lower). All bases are not afraid of moisture.

   

2. Bitumen impregnation. It is available on both sides of the roll, and special innovative additives are added to increase resistance to UV rays, plasticity at sub-zero temperatures and maintain characteristics after heating to +80°C.

   

3. Protective polyethylene film. Purpose - prevention of sticking of rolls during transportation and storage. Lining bikrost has such a film on both sides, finishing only on the back.

   

4. Sprinkling of mineral or natural stone. Only available on front side finish rolls. The purpose is to protect bitumen from harsh ultraviolet radiation and improve design characteristics.

   

Specifications and types of material

Depending on the purpose, each type of material has its own marking.

Recommendations for use in the regions, depending on the temperature conditions of operation, are prescribed in SNiP 23-01. In terms of combustibility, bikrost belongs to the G4 group, in terms of the speed of fire spread to RP4, in terms of ignition temperature - B3. These characteristics indicate that it is considered a flammable material, work requires compliance with all safety precautions.

Step-by-step instructions for laying bicrost

To begin with, consider an interesting option for using an automobile HBO to connect a gas burner. Currently, many motorists have begun to abandon gasoline engines due to the constant increase in the price of fuel. HBO is not uncommon, motorists have switched their cars to this cheap and environmentally friendly fuel. Such equipment makes it possible to connect the burner directly to it, there is no need to borrow or buy a gas cylinder.

Burner connection method

How is the connection made?

Step 1. Park the car as close as possible to the garage or other structure that you plan to cover with bicrost.

Step 2 Open the hood and remove the plug from the gas supply unit. It is located above the cylinder head, has a rectangular shape, most often it is blue. An important distinguishing feature is that rubber hoses extend from this device to each engine cylinder. The plug is located on the side, made of plastic. It is taken out from a technological nest with average effort after release of the holding lock. Pull it towards you and open the hole.

Step 3 Put the adapter on the freed branch pipe. This is an ordinary hose of a suitable diameter. To ensure tightness, tighten it with a clamp.

Step 4 Insert a piece of metal tube into the other end of the rubber adapter and also tighten the connection with a clamp, attach the burner hose. Start the engine and you can start fusing the rolled roof.

Such actions take only a few minutes and save time. There is no need to lose it in search of a gas cylinder, check serviceability and warranty period, visit a special gas station. It remains only to raise the materials and tools to the roof and proceed with the work.

Bicrost laying

For high-quality laying of roll coverings, an even, clean and solid base is required. If there is an old worn coating with numerous damages, it is better to completely dismantle it or at least remove the most damaged areas.

If the building has been in operation for a long time and a major overhaul of the structure is planned in the coming years, one layer of bikrost will be enough to temporarily protect the roof from precipitation. It is this example with the use of cheap coverage that we will consider. In all other cases, laying should be carried out in at least two layers with the obligatory overlapping of the overlaps of the lower sheets.

Step 1. Thoroughly clean the floor surface from various debris, vegetation and dirt. Align the protrusions. Seal deep cracks and pits with a cement-sand mixture. Take all measures to ensure that a cheap bicrost with a weak base does not have mechanical damage.

Step 2 If there was an old soft roof on the roof, then it is necessary to inspect it for blisters and delaminations. Such places are opened and melted separately, you can cut off small pieces from a new roll and cover the surface. But in most cases, repairs do without patches; leaks do not appear due to swelling. It is necessary to straighten them so that the new coating does not stretch and is not damaged. These are preventive measures of the same type as leveling a concrete base.

Step 3 All vertical joints must be glued in at least two layers, regardless of their number on a horizontal roof. The fact is that in these places there are maximum displacements of architectural elements, which significantly increases the risk of leaks.

Step 4 Start laying the bicrost on a horizontal surface. If laying is carried out not on the old coating, but on a screed, the surface is pre-primed with liquid bitumen. Roll rolls only on yourself, try not to walk on a hot soft surface. We have already said that the cheapest bikrost with a fiberglass base is used. The word canvas itself does not mean that it is a durable canvas fabric familiar to many consumers. In fact, it does not have threads; it is not made on looms, but by pressing thin fibers. Such a coating is characterized by minimal strength and requires very careful handling.

Practical advice. The burner must heat not only the bicrost, but also the roof. Due to this technology, the adhesion of the coating to the base is significantly increased, it does not matter if it is a concrete slab or old bitumen.

It is necessary to heat the reverse side of the roll, there is a special polyethylene film on it. It should not burn, but the bitumen should boil and bubble. Do not allow overheating, if burnouts appear on the front side, then this is a marriage, after the end of the deposition of materials, patches will have to be installed on them. At the optimum heating temperature, the film becomes transparent, it completely melts, and the bitumen softens greatly, but does not boil or burn.

To facilitate the process and increase the safety of the work, roll out the roll with any improvised device, you can bend an ordinary wire. Work only in dry weather at positive air temperatures.

Step 5 The second roll must be rolled out in such a way that its edge lies exactly on a special edge without stone chips. If the laying process is correct, then molten bitumen should protrude along the entire overlap line.

Step 6 After the entire flat part of the roof is covered, carefully finish the adjunctions. It should be remembered that all the most dangerous places are best sealed with two layers.

Important. Rolled bikrost has bituminous impregnation on both sides. The bottom must melt, it performs two tasks: it tightly connects the coating to the base and does not let water through. The top impregnation only seals the roof.

Bicrost trimmings left after laying the roof should not be thrown away. If a marriage was made during the work, and swellings, delaminations or depressions appeared on the coating, with the help of these pieces it will be possible to eliminate defects by applying neat patches.

And universal advice - never rush, built-up roofs react very negatively to any deviations from the recommended laying modes.

Video - Bikrost: what is it

You have learned the technical parameters and performance characteristics of Bikrost. But this is not the only roofing material produced by TechnoNIKOL. It produces a wide range of coatings of excellent quality. For the right choice, you need to know their capabilities, you can read about the brief characteristics on.

As a rule, when building private houses, pitched roofs and various configurations are often formed.

It is understandable, such a roof will not leak for many years, since there is nowhere for water to accumulate and, therefore, the surface does not suffer from excessive dampness.

But, if you still want to build a roof with a flat surface, then know how bicrost laying is simply vital for you.

Laying this type of roofing with your own hands is not as simple as, for example, tiled, but at the same time it saves both space and your money on the coverage area. After all, roll roofing is a cheap and aesthetic option, which is designed specifically for flat surfaces and creates an outer layer that does not allow moisture to pass through.

The simplicity of this type of roof lies in the fact that it can be laid directly on top of a conventional sand-cement screed, without fear of displacement or deformation of the coating.

True, before starting roofing work on laying bikrost, all necessary work on hydro and thermal insulation must be carried out. And among other things, the built-up laying of bikrost can also be used for cosmetic repairs of the old roof.

The technology of laying bicrost on new roofs involves the fusing of two different layers of material (difference in characteristics), and when repairing, it is enough to use one layer of rolled roofing.

Briefly about the varieties:

Bikrost "HPP"- has a base made of ordinary fiberglass, on which a dense bituminous layer mixed with specialized additives is successively applied. Both sides of the base are covered with a special protective film. It is most often used as a bottom layer when laying new built-up roofs.

Model "HKP"- differs in that the upper protective layer is made of granulate. Used for laying the top layer of a new roof in the same way.

Model "TKP"- essentially the same as the previous Bicrost model, but excellent in terms of improved performance and able to withstand more external influences.

Bikrost "TPP" also used for laying the lower roofing layer, usually in combination with the top layer of "TKP". There is a protective film on the bottom.

Is it possible to lay a bikrost with your own hands?

As you can already understand, unlike tiled and slate roofs, bikrost has many positive qualities, designed not only for long-term use, but also for ease of repair after laying such a surface.

Laying it for the first time with your own hands is a rather difficult task.

What tools are needed when laying bicrost?

In order to do the work with your own hands, you first need to purchase the necessary equipment. We will need a gas cylinder and a burner for it. You will also need bitumen (resin). Cement + sand for mortar preparation.

Stages of laying bikrost.

1. The very first moment we level the roof, excluding depressions, with cement mortar.
2. Next, we heat the bitumen and cover it on a flat roof surface so that the bicrost adheres well to the roof surface.
3. By heating the bitumen applied in a thin layer on the roof, we evenly unwind the bicrost roll, gluing it to the flat surface of the flat roof.
4. Bicrost rolls are rolled out with an overlap of more than 6-9 cm, all work is carried out, of course, from the bottom up. At the ends of each roll, the overlap should not exceed 15 cm, otherwise, after laying it in the next month, it will simply peel off.
5. That is, the roll is simply rolled out, after which the overlap of the rolls you need against each other is measured, and then it rolls to the middle. Laying it with your own hands is done with a preheated gas burner, with the help of which the material is given a slightly fluid consistency, and then rolled with a hand roller.

Remember.

Never walk on a freshly welded roof! Firstly, you will leave dents all over the surface, and secondly, you will melt the sole of your shoes and risk getting burned.

Outwardly, everything looks simple, but in reality this is a very delicate work that requires professionalism, and if you are not sure that you can lay the bicrost with your own hands, then it is best to trust the people for whom this business is a profession, letting them do all the hard work for you. You will only have to enjoy the result and a strong roof over your head.

An integral part of the process of arranging the roof of any building is its waterproofing. Moreover, the choice of one or another material directly depends on the type of roof. In this article we will talk about such a popular material as Bikrost - what it is, what are its varieties and technical characteristics. In addition, we describe the sequence of work with this material, give a few recommendations.

"Bikrost" - what is it

Bikrost roofing is one of the affordable types of rolled materials, which is of noticeably higher quality than, say, ordinary roofing material. The main purpose of such a roof is to protect residential or industrial buildings from moisture and damage to ceilings, load-bearing structures and other property. It is worth noting that bicrost is most preferable in the case of flat or slightly sloping roofs.

We can name the following examples of the use of this material:

• arrangement of the upper or lower layers of the roof;
• providing waterproofing of load-bearing structures in large engineering structures - bridges, tunnels and others;
• replacement of old roofing materials whose service life has expired;
• laying on a hard subfloor in rooms requiring additional waterproofing, such as basements or basements.

Roofing material bikrost consists of the following components:

• polymer film and a layer of fine gravel;
• oxidized modified bituminous layer;
• fiberglass - fabric or canvas;
• another layer of modified bitumen;
• a layer of polyethylene film to protect bicrost from sticking together during transportation and storage.

Among the main advantages of the material are the following possibilities:

1. The working temperature range of the material is from -30℃ to 50℃.
2. Bicrost laying can be carried out at an air temperature of 0 ℃ (details: "").
3. The structure of the material ensures its high mechanical strength.
4. Provides high quality insulation and waterproofing.
5. The service life of the material is at least 10 years.
6. Bikrost can be used to repair a damaged roof by laying it on top of the old coating. In addition, it can also be used as the main roofing material.
7. Installation is very quick and easy.
8. The material is available to most buyers due to its low cost with good quality.

Mounting method

By and large, no special skills are required to work with bicrost. However, you still have to acquire a certain set of tools and monitor compliance with certain standards.

In order to cover the roof with a bikrost, you need to perform a certain list of works.

At the initial stage, preliminary preparation of the roof should be performed. The old, worn-out waterproofing coating must be dismantled and the surface cleaned of dirt.

If the previously laid material has been preserved in good condition, it can serve as the basis for laying the bicrost. However, it will need to be prepared for additional processing before further laying of new waterproofing.

The next step is the actual processing of the rough surface. In this case, there are a number of subtleties. In particular, if cracks are found on the old coating and it has become permeable to moisture, it will need to be repaired. All cracks are filled with bituminous mastic, which is able to clog defects, returning the material to its original properties. However, this method is applicable only in cases where the total area of ​​damage does not exceed 10% of the surface.

After the mastic has completely dried, the treated surface is covered with a primer layer. It is needed for the subsequent adhesion of the bicrost to the old insulating material and to prevent delamination of the roof.

Now you can get to work with the bicrost. Since it is sold in rolls, before laying it, it must be rolled out on a flat surface and left for a while to straighten it out. After that, the material is cut to the specified dimensions.

During the laying process, in order for the bicrost to adhere to the roof surface, it must be heated. To do this, you will need a propane or butane gas burner.

Start work from the edge of the roof. Heating the end of the roll with a gas burner, it is pressed to the surface. Next, the roll is gradually rolled out on the roof and heated. At the end, the laid bicrost is rolled with a heavy hand-held iron roller so that the material grabs well.

As soon as the laying of the first roll is completed, you must immediately take on the next one. The installation of each next layer of bicrost is carried out with an overlap of 10-15 cm. Thus, complete tightness of the seams is achieved, and moisture does not enter the space between the rolls.

After laying, the tightness of the joints must be checked, since any pores and gaps will lead to a violation of the integrity of the coating.

1. Before starting work, the roof surface must be thoroughly cleaned of dirt and dust, and shortcomings and defects in the rough coating must be eliminated.
2. The installation of the bicrost must be carried out from the bottom up so that the water is gradually drained from the roof.
3. It is convenient to roll out and warm up the rolled material using a hook without sharp edges.
4. To work at height, workers must be provided with safety belts.
5. Since the operation of gas burners can be hazardous to health, work should be done in special clothing and a respirator.

Varieties of "Bikrost"

Manufacturers make bicrost of two varieties - lining and roofing, therefore, they are marked with the letters "P" and "K".

For laying, "Bikrost P" is used as a waterproofing intermediate layer. It has a double-sided bituminous base, and is covered with a fusible film on top.

But "Bikrost K" serves as a finishing waterproofing material for roofing. The lower part of such a coating consists of bitumen, and fine and coarse-grained granite chips are located on top.

Explanation of designations

There are a number of varieties of Bikrost roll material, therefore, to determine the composition, it is marked with a three-digit letter code.

Here is the decoding of the letter designations:

1. P - the presence of a polymer film.
2. K - large gravel crumb.
3. M - mineral dressing with a fine fraction.
4. C - the basis of the material is standard fiberglass.
5. T - frame fiberglass is used.
6. X - the base is made of fiberglass.
7. E - polyester non-woven fabric in the basis of the material.
8. A - the basis is a specialized cardboard.

The brands KhPP, TKP, HKP, Chamber of Commerce and Industry are in the greatest demand, EKP bikrost and other products are also of very high quality, although they are bought somewhat less frequently. In addition to the composition, the marking indicates such characteristics of the bicrost as weight in kg / m 2, as well as the color of the mineral crumb and the specifications used in the production. Note that the thickness of the bicrost will also depend on the component composition, which it is desirable to take into account when carrying out work.

Material Specifications

The technical characteristics of bicrost, depending on the brand of products, may differ slightly, since their component composition is also different.

Consider the main parameters of various grades of material:

• Bikrost HPP- This is a material used primarily as a lining waterproofing. It is based on fiberglass, on which a layer of bitumen is applied on both sides. The upper part of the roll material is covered with a protective film that prevents the layers from sticking together. The characteristics of the HPP Bicrost do not allow its use for any other purposes, since it does not have high mechanical strength.
• Bikrost brand HKP is more durable, so this material is used as the main roof. In this case, fiberglass also serves as the basis. On the front side, a layer of mineral crumbs of a large fraction is applied to the base, and a layer of oxidized bitumen is located below. A fusible film protects the rolled material from sticking together.
• TCH- This is a kind of bicrost, which is based on fiberglass. The front part of the material is covered with a mixture of bitumen with gravel dressing, and the wrong side consists of a bituminous layer. This bicrost has good mechanical strength and is mainly used for inverted roofs.
• Bikrost CCI at its core contains frame fiberglass, which is covered with bituminous layers on both sides. Therefore, this type of material is used to perform lining waterproofing. This kind of bikrost shows itself well in combination with the HKP and TKP brands.
• Bikrost SPP- This is the cheapest type of rolled waterproofing. It consists of a base layer of standard fiberglass, which is coated with a mixture of bitumen with fine granite granules on one side and oxidized bitumen on the other.

Storage conditions

Please note that bicrost roll wrappers tend to stick together. Therefore, you need to store it only in an upright position, without stacking several rolls on top of each other. If stored improperly, even protective films are not able to prevent sticking.

In addition, bikrost should be stored only indoors, without direct sunlight and precipitation, at a temperature not lower than -10 ℃.

Results

Thus, thanks to the variety of bikrost types, everyone will be able to choose the best option for themselves and enjoy a serviceable protected roof for many years. At the same time, installation will not take much time and effort.

Bikrost is a bitumen-based roll material, which is an improved version of the well-known roofing felt. It is used for arranging roofs for various purposes, as well as for waterproofing elements of building structures.
Bicrost laying technology involves the use of open fire to melt the coating of the inner layer, therefore, it provides for the use of this type of coating only on surfaces made of non-combustible materials (we advise you to read about).

Preparing the base for laying

Bikrost, like all other types of soft roofing, is very sensitive to the quality of the working surface. It requires a solid, dry base without any unevenness. Therefore, before starting work, it is necessary to clean the entire plane of the roof from dust, dirt and foreign objects, and repair all cracks and depressions with cement mortar or putty. It is also necessary to ensure that there is no moisture and traces of the old coating on the entire treated area.

To ensure a stronger contact, the surface of concrete or cement screed is treated with a special primer mixture called a primer. For these purposes, you can use finished products or dilute bitumen yourself in gasoline or kerosene in a ratio of one to three. The primer is applied with a roller.

Covering the roof with bicrost can only be started after the primer is completely dry. You can verify this by running a clean, dry cloth over it - no traces should remain on it. The primer is applied in a thin even layer using brushes or rollers, the approximate consumption is 300-400 g per square meter.

Features of bicrost laying

In order to most effectively use this material in the production of roofing work, the following recommendations must be considered:

Bicrost roof covering

The device for waterproofing with rolled bituminous materials is a relatively simple procedure that you can perform on your own. This requires only general knowledge in the field of construction and skills in working with a propane torch. Next, we will describe in detail how to cover the roof with a bikrost and try to describe all the subtleties of this work.

We suggest you familiarize yourself with the step-by-step video instructions for laying the bicrost:

In conclusion, here are some more simple tips on how to lay bikrost for those who are going to do roofing work on their own:

• It is better to lay a soft roof at an air temperature exceeding + 5 ° С. If it is required to work in the cold season, the material must be kept at room temperature for a day;
• The flooring of the sloping roof is made from the bottom up to exclude the possibility of leaks at the joints of the canvases;
• When choosing a roofing material, it must be borne in mind that the service life of bicrost coatings is 5-8 years;
• When calculating the right amount of material, do not forget to provide for a margin for organizing the joints of the canvases with each other.

Bikrost is the best option for waterproofing the roofs of garages, warehouses and other outbuildings. It is perfect if you need to quickly and inexpensively cover the roof on your own.

Most often, garages and other outbuildings are built with a flat roof, which has a slight slope, no more than 20 degrees. The best option for covering such roofs is Bikrost roll roofing, which is described in more detail below. Read an overview of the characteristics of the foundation for a cinder block garage.

Choosing the right Bikrost brand for roofing

This building material is divided into technical characteristics, and is widely used in construction.

Main marking:

HKP - marking is intended for soft and hard roofing. The base is fiberglass on both sides, a bituminous layer is applied, coated on the front side, a layer of mineral chips is applied.

HPP - bikrost is used for waterproofing, as a lining on the foundation, basement. etc. It does not have such high strength as materials intended for roofing.

What's the best way to cover?

Bikrost is a special building material used for roof waterproofing. It consists of fiberglass impregnated with binders, based on glued bitumen. Its characteristics meet the highest quality requirements, and therefore, its use is not limited only to waterproofing, it is used to cover flat and soft roofs. Check out the guide on how to calculate the foundation for a garage.

Bikrost has a number of advantages:

1. durable material
2. Not subject to decay
3. The presence of the top dressing protects the fabric from UV rays.
4. Can be used as a vapor barrier, waterproofing
5. Resistant to various weather conditions, thanks to which it is successfully used in any climatic zone of the country
6. The ratio of excellent quality and affordable price

Bikrost is glued to the roof by melting the bituminous layer on the coating, this procedure is performed using a gas burner. Since there is an open fire during laying, Bikrost should only be laid on top of non-combustible materials. When covering a soft roof with a wooden gable roof, open fire is used with caution or excluded altogether.

How to cover?

Before laying Bikrost on the roof, the roof surface should be prepared, since the material is soft and demanding on the quality of the base:

• The base must be dry;
• The complete absence of various irregularities;
• The roof surface must be cleaned of dust and dirt, as well as any foreign objects;
• Even the smallest cracks and dents must be repaired with cement mortar or putty;
• Then treat the surface with a primer for the best adhesion to Bikrost.

The very technology of covering the roof of the garage with Bikrost is as follows:

• The rolls are laid out across the slope, keeping an overlap of at least 8 cm;
• All work is done strictly from the bottom up;
• From the end part of the rolls, the overlap is observed from 15 cm;
• The ends of different rolls should not form a single joint line, so they should be displaced relative to each other;
• The required length from the roll is rolled out, here the overlap is taken into account;
• Then the segment is rolled from both sides to the middle, heated by a gas burner and pressed against the working surface by a roller;
• The rolling process itself takes place from the middle to the end, on each side. Attention! It is impossible to walk on a rolled and freshly welded roof, as the integrity of the coating is violated, as a result of which the waterproofing is also violated;
• During rolling, it is necessary to ensure that there are no folds and wrinkles;
• When rolling out the first layer, you should immediately take care of covering the vertical abutments of the roof, if any. To do this, a small piece of 40 cm in size is cut off from the bottom layer of Bikrost, of which 25 cm will go to cover the vertical surface, the rest - to cover the horizontal surface.

How much does it cost to make a Bikrost garage roof?

The cost of covering the roof of the garage with Bikrost varies from 150 to 250 rubles per square meter. m. Much depends on the condition of the original base and the required number of layers. If the roof is in poor condition, then the cost of the work can be significantly increased. This price does not include the price of the material. Read and how to build.
