Installation of a plastic drainage system. How to install gutters: ways to connect gutters and pipes Do I need to glue a plastic drain

Quite often, when choosing a drainage system, the question arises of which one to install - plastic or metal. Very often, one of the reasons for refusing plastic gutters is that they burst in winter.

Let's see if this is true and why it happens.

We note right away: indeed, sometimes plastic gutters burst, but this does not mean at all that they are of poor quality or worse than metal ones.

Any material shrinks or expands when the temperature changes. For example, frozen water turns into ice and increases in volume. The same thing happens with drains, only without changing the state of aggregation - they change sizes. The coefficient of linear expansion of plastic is much greater than that of steel, that is, a plastic drain changes its dimensions depending on the ambient temperature difference more than a steel one. The coefficient of linear expansion is an important parameter that must be taken into account when installing and operating a drain.

Different manufacturers of plastic systems have different mounting technology: some use adhesive bonding, while others use joints with rubber seals. In the first case, all elements are rigidly fixed to each other with glue, which prevents the system from “walking”. When installing such a drainage system, it is imperative to install special elements that will compensate for these expansions. In the second case, the role of expansion elements is performed by connecting elements with rubber seals, which exclude leaks at the junctions and at the same time maintain the mobility of the system.

To increase the service life of rubber seals, manufacturers recommend using silicone, it prevents premature aging of the rubber seals and ensures free sliding of the elements during expansion. It is important to clarify that you need to use silicone paste, it acts as a lubricant for rubber bands, and not silicone sealant, which hardens after some time.

Let's deal with a real situation: we install a gutter on the eaves of a house 10 m long in the summer at a temperature of 20 ° C. The coefficient of linear expansion of plastic (polyvinyl chloride) 70 * 10 -6 ° C -1. In winter, the temperature drops to -20 ° C, i.e. the temperature difference was 40 °C. With such a change in temperature, the change in the length of a 10-meter plastic gutter will be (10 m * 40 ° C * 70 * 10 -6 ° C -1) 28 mm!

Under the same conditions, the change in the length of the metal chute will be only 4.8 mm (Coefficient of linear expansion of steel 12 * 10 -6 ° C -1).

This is theory, but what about practice? In practice, when a plastic drain has nowhere to expand or narrow, it does it anyway, as a result of which the most loaded elements burst, for example, the corners of the gutters.

During operation, it is imperative to maintain drainage systems: remove foliage accumulated in pipes and gutters. If this is not done, foliage and any other debris prevent the movement of rainwater that accumulates in the elements of the drainage system, and when it freezes, it all turns into ice, which, as already mentioned, expands in volume, which is why deformation occurs, and elements are broken.

Expansions also occur in steel drains, but due to the fact that they are not so significant, and steel is stronger than plastic, the elements of the drain do not burst.

So, we figured out the two main reasons why plastic drains burst in the winter:

1. The inability of the drain to expand linearly with temperature changes;

2. "Garbage" in the system that prevents the drainage of water from the drain.

To avoid such problems, in the first case, it is enough to follow the installation instructions of a particular manufacturer: use expansion elements; apply adhesives and sealants only to those elements for which such a need is indicated. In the second case, it is obligatory to carry out an audit and maintenance of gutters 2 times a year - in spring and autumn before the onset of frost.

We hope that our article will help you choose a drainage system and avoid problems with its operation in the future.

The work of the drainage system of the roof is almost invisible? until water begins to flow from the gutters under the threshold and foundation of the house. The cause of leaks can be depressurization of the seams or a defect in the drain itself. Sometimes this happens if sealant was not used at all during the installation of the drain due to economy. The use of the same sealant again will help to fix this and that problem, only the entire system will have to be disassembled and reassembled.

The most suitable sealants for the installation of gutters

It is reasonable to start a review of gutter sealant by determining what kind of substance it is. Their appearance resembles a thick mastic or paste. The viscosity of the sealant is given by polymer additives or oligomers. Mastic is applied to any connection, as a result of which the joint is sealed. Sealant after hardening firmly adheres to the surface of the treated object. It turns out a kind of waterproofing of the seam of the connected parts, which prevents the penetration of moisture.

On the shelves of retail outlets you can find a huge variety of sealants for different types of work. In wide consumption, 4 types of mastic are usually used, made on the basis of different components. Which one is better suited for sealing drains, we will now try to find out.

One of the most used sealing mastics is silicone sealant. After it hardens, a strong elastic seam is formed on the surface of the object. Mastic can be white or transparent. The basis of the paste is silicone rubber. For ease of use, it is most often sold in plastic tubes with a capacity of 310 mm. It is enough to insert the balloon into a special gun nozzle, and the sealant can be used. Sometimes you can find other packaging of pasta on the shelves, for example, like tubes of toothpaste.

Silicone sealant is produced in two types:

• Acetate composition Designed for use on smooth surfaces. Mastic is characterized by a pungent odor, however, it tends to quickly disappear.
• Neutral composition has a lower adhesion strength to the surface of the object, so it is often used for interior work. Mastic is ideal for the bathroom and kitchen. Excellent adhesion to tiles, wood, glass.

Silicone sealant is often used in the assembly of porches, greenhouses, gutter systems and other structures where waterproofing of joints is required.

Any acrylic-based sealant is less flexible than silicone, but adheres well to plastic. However, acrylic has a significant disadvantage - it dissolves in water. As a mastic for connecting drains, acrylic sealant is not suitable. Moisture intolerance is explained by the base of the mastic, consisting of an aqueous dispersion. Such a paste is better suited as a sealant for sealing joints of any structures. These can be cracks in door and window jambs, as well as any other non-damp places.

Now in retail outlets you can find white acrylic sealants with the inscription - moisture resistant. Mastic is really resistant to moisture after complete hardening. However, such contact can only be short-term. From long exposure to water, even a hardened acrylic layer will dissolve. Moisture resistant acrylic sealant is not suitable for sealing or patching a gutter. It is undesirable even to use mastic in the kitchen and in the bathroom.

The basis of polyurethane mastic is polymerized resin. The sealant withstands low temperatures. It is successfully used for sealing inter-panel joints, double-glazed windows of buildings with a swimming pool or a winter garden.

Polyurethane mastic is produced in two types:

• Sealing paste designed for use on a dry surface. It's a kind of sealer. Such a sealant is not suitable for drains.
• Waterproofing paste can be used in humid environments and even long contact with water. This type of polyurethane sealant is suitable for processing drain joints.

Often polyurethane mastic is used to seal the roof, but for this purpose a substance with a hardness index of PU 15 is used. The sealant is characterized by rapid hardening, resistance to moisture and chemicals, and a long service life. The solidified substance can be successfully dyed.

Attention! Among other mastics, polyurethane sealant is considered the best due to its versatility of use. The paste has excellent adhesion to wood, metal, tile roofing.

The only drawback of the sealant is the high cost. Because of this, polyurethane paste is practically not used in the installation of drainage systems.

The basis of the mastic is modified bitumen. Due to the addition of a metallic pigment, some types of bituminous pastes have an aluminum tint. The scope of the sealant is wide: sealing and sealing chimneys, drains, air ducts, ridges, and other structures.

Bituminous pastes are characterized by increased resistance to water and good elasticity. Mastic has increased adhesion to the wet surface of the object, and after hardening it can be painted. Affordable price has made the sealant popular in the installation of drainage systems. Among many brands, Icopal sealant has an increased consumer demand due to its high quality.

There are bituminous pastes specially designed for roofing. They are not even affected by gasoline, thinner, machine oil and other chemicals.

The disadvantage of bituminous pastes is an ugly black color, despite the addition of pigments. Plus - bitumen is afraid of exposure to high temperatures, from which it begins to melt.

Attention! All bitumen-based sealants are toxic. They are only allowed to be used outdoors.

Butyl-based mastic is the ideal solution for sealing joints with a gutter. The paste has excellent adhesion to aluminium, PVC, galvanization, well tolerates latex and oil paints. White sealant is characterized by a high rate of elasticity, resistance to moisture and negative temperatures. In addition to sealing joints, the paste is ideal for repairing deformed gutters. Sealant can be used to seal small cracks, and even small holes.

Attention! It is possible to work as a sealant at negative temperatures, but in order for the paste to be squeezed out better from the tube, it must first be kept at room temperature.

The instructions for applying the sealant are simple:

• It is optimal to carry out work with mastic at a temperature above +4 ° C. Old accumulations of paint, putty and other dirt are removed from the surface of the workpiece. If the metal drain has corroded, the rust is cleaned with a metal brush. The completely cleaned surface is left to dry.
• A tube aged at room temperature is inserted into the gun. There are notches on the plastic tip, each of which is designed for a certain thickness of mastic extrusion. With a sharp knife, cut off the nose of the tip along the required notch, and also remove the membrane at the end of the thread of the tube, which prevents the sealant from being squeezed out.
• Having screwed the tip onto the thread of the cylinder, they begin to squeeze the sealant onto the junction of the drain with the trigger of the pistol. When sealing a hole in the gutter with a diameter of more than 12 mm, a tire is applied from a piece of plastic or metal.

The paste will begin to harden after 5 minutes. During this time, it is necessary to remove the excess protruding at the joints of the gutters, and where the patches were installed, the mastic is smoothed with a scraper. The joint will gain full strength in 5 days, but it is possible to paint the frozen layer in a day. The sealant can also be used in a humid environment, but cure time is increased by 10%. The approximate consumption of sealant with a layer thickness of 6.5 mm is 10 p.m. If necessary, remove the hardened layer using a cleaner of the same company or any mineral solvent.

When is it necessary to use sealant when installing gutters?

The use of sealant to connect the joints of drains is justified in the case of their self-production. Often, due to cost savings, gutters are cut out of PVC sewer pipes with a diameter of 100 mm. The joints of each such gutter are fastened with self-tapping screws, and so that they do not leak, they are additionally coated with silicone or bituminous sealant.

Factory drains are equipped with connecting locks with sealing rubber bands. A strong connection does not leak even without mastic treatment. But for reliability, it does not hurt to lubricate the seal with the same silicone. Usually, the contents of 1 tube with a capacity of 0.3 liters are enough for 10 locks.

The video shows the process of sealing the roof and drain:

Regardless of the quality of the gutters, depressurization of the seams will lead to a disruption in the performance of the entire system. Saving on sealant is unreasonable and unprofitable.

The greatest damage to the walls and foundations of houses is caused by uncontrolled flows of moisture flowing down from the roofs. Soft rainwater is able to wash the most resistant finishing materials. For external thermal insulation made of mineral wool or basalt felt, even a small stream of water can be a death sentence. It is not difficult to prevent such problems if effective drainage systems and a drain are installed at the places where the water drains. Effective - this means that in any weather and the most extreme rains and winds, the margin of safety and performance of the catchment and drainage system is enough for a normal flow of water from the roof without seething waterfalls.

What should be the system for collecting and draining water from roofs

Before embarking on the development and installation of your plastic drain scheme, you should think twice and not reinvent the wheel, but buy a ready-made set of plastic pipes and gutters for the drain and assemble the desired design from them.

The system of plastic drainage and water collection from roofs must meet several specific requirements:

• The plastic construction of gutters and gutters must be installed on a strong and rigid mount so that the weight of water or a mixture of ice, melting snow and water does not break off the system supports and cause the gutters to deflect;
• Set the angles of inclination of the gutters of the drain, allowing the flow of water to drain quickly enough to the catchment funnel or volute, but at the same time there should not be shock tidal waves that can overflow over the edges of the collectors;
• The joints of the gutters with a funnel, transitional elbows, drain pipes must have tightness, rigidity and a margin of safety, so that in the event of a break even one or two attachment points, the entire system retains its operability until the moment of repair.
• All pipes and gutters of a plastic drain must be resistant to corrosion, frost, moisture and solar ultraviolet;

Important! The most common "ailment" of cheap plastic fakes of gutter options is the appearance of a huge number of cracks from exposure to ultraviolet radiation.

The problem of fakes from well-known manufacturers very often confuses not only ordinary buyers, but even experts. Often, a well-known company sells the right to manufacture its products to Chinese or Vietnamese plastic fittings factories, with the condition of selling products only in the CIS countries. As a result, in Russia you can buy under the same brand both a high-quality drainage system and a fake from crumbling plastic recyclables.

Which plastic drain to choose and install on the roof of the house

The choice of the most effective system largely depends on financial capabilities and time. Most often, there is not enough money or time to make the right decision, so you have to choose:

1. If you have enough funds and opportunities, you can simply buy the most sophisticated drainage system that the seller or “expert” in the salon will offer;
2. You can do it easier - choose a popular brand, such as Döcke, RainWay, Profill or Eslon BV. It will be somewhat more expensive than buying on the market, and there is a chance to run into a fake, but in general, the plastic drain designs of these manufacturers have a good reputation, which is confirmed by available product reviews in the CIS;
3. Use the products of Russian companies or enterprises with foreign capital that create a reputation for high quality products - Murol, Vinylon, Alta-Profile, Rohrfit.

Products Alta-Profile

The practice of working with the products of the companies listed in the last list shows that while any of them is in the stage of conquering the market, the quality of plastic roof drainage systems is maintained at the proper level, so do not be afraid to take risks and buy high-quality plastic products at an affordable price.

The Alta-Profile product list contains everything you need to assemble and install a roof drainage system. The company positions itself as a manufacturer of both individual components for the drain, and the branded roof drainage system "Alta-profile".

If desired, Alta-Profil specialists can help install gutters, subject to the purchase of systems for their development. The work of the installers Alta - Profile is estimated at about three hundred rubles per meter of the installed drain. That is, the price of the service of an Alta-Profile specialist to install a gutter will be equal to the cost of a meter of a plastic gutter from the same company. For those who wish, there is a special calculator on the site from Alta-Profil, which allows you to calculate material needs, estimate how much it costs to install a specific version of a plastic drain, and leave your feedback on the quality of a plastic drain.

It may be cheaper to simply buy the necessary gutter kit from plastic gutters, pipes and elbows, and install the gutter on your own:

• Plastic drainage gutters of a special configuration.
• Pipes and elbows for the formation of drainage outlets.
• Drainage plastic funnel with rubber seals;
• A socket for straightening the flow of water in the right direction, this will ensure proper drainage from the base of the foundation of the house;
• A set of brackets and fasteners that allow you to fix the gutters on the roof and pipes on the vertical walls of the house.

Note! According to the company, most plastic gutters do not have a round section, but a special profile in the form of a semi-ellipse. This increases the rigidity of the structure, and reduces the likelihood of overflowing the flow of water over the edges.

Alta-Profile experts guarantee the resistance of plastic fittings to frost and ultraviolet radiation. Polyvinyl chloride, in addition to high resistance, has good resistance to erosive wear from sand and dust. That is, scratches and abrasions will appear on the surface, but it will be difficult to visually examine them, due to the coloring of the plastic wall of the reinforcement to the entire depth of the material.

For situations where the structure of the roof of the house does not allow installing a sufficient number of fasteners and supports for gutters on the roof or truss, the company suggests using reinforced gutters with special profiled walls and reinforced sides. Thanks to this, the plastic drain will not bend and lose the angle of water discharge.

Alta-Profil offers several options for colors and designs of gutters and pipes. For conventional drains, a gutter measuring 11.5 cm wide and a pipe 7.4 cm in diameter are offered. For roofs with a large roof area, you can order a structure with a 20% increased throughput.

How to install a plastic drain on your own

Almost all gutter systems sold under branded brands are designed for a simplified method of installing components. That is, it is possible to install gutters and pipes without the use of special devices for plastic welding. An exception is the system of supports and brackets. Before mounting, you need to establish their exact location on the roof or on the walls, subject to a few simple conditions:

• Maintain the recommended angle of inclination of the catchment gutters to the place where the funnel is attached;
• Set the distance of the drain pipe from the foundation at a distance of at least 400 mm.

At the first stage, the place of the gutter suspension and the line of inclination to the horizon are marked. The farthest point of the gutter system should be at the highest catchment point. At this point, it will be necessary to install a plug on one side of the gutter. The second side is directed to the place of collection of water. From fastening with the help of a building level and a long ruler, we mark the point where the next bracket is supposed to be installed. In this case, the attachment point of the next bracket must be set lower by a certain number of millimeters to maintain the angle of inclination.

After fixing all the brackets with dowels or self-tapping screws, you need to install plastic gutters and pipes. In the corporate version, they are assembled on rubber seals, snapping into the funnel and pipe clamps, as in a children's designer. In cheap versions of the drain, pipes and gutters can only be installed using sealant or branded glue.

Be sure to check the rigidity of the gutters. To do this, it is enough to install a load with a weight of 250-400 g in each span between the attachment points. This is the average load per meter of gutter during rain. After a couple of hours, it is necessary to set the level and check the degree of change in the position of the pipes and gutters relative to the original fastening. With high-quality fasteners, there should be no changes in the angle of inclination of the current.

The operation of buildings and structures without an established effective eastern system leads to critical destruction of very important architectural elements. First of all, the basements suffer, then the foundation and the basement of the building begin to collapse. The bearing capacity of these structures is significantly reduced, as a result of which cracks appear on the facade walls.

But this is not all the problems caused by high soil moisture near the house. With a significant increase in the amount of water during freezing, swelling of soils far exceeds the calculated maximum values. If the foundation has a large margin of safety, and the building is built from lightweight materials, then only minor problems with opening / closing windows and doors can be observed. But if the walls are made of masonry bricks, and the foundation does not have such significant margins of safety, then cracking of the walls is inevitable. The consequence is the destruction of load-bearing structures and elements, the inevitable very complex and expensive repairs.

The destruction of the facade of the house in the absence of a drain is a matter of time

Important. During the design of houses, no one lays in the strength of the foundation the influence of the above factors due to the lack of a spillway system. Such a huge margin in terms of bearing capacity greatly increases the estimated cost of construction. It is always meant that there is a blind area around the house, and all water from the roof is diverted far beyond the foundation or into special engineering sewer networks. Today, for these purposes, companies produce very efficient, durable and reliable gutter systems.

drains

All the huge number of models of structures is divided into two large groups, depending on what material they are made of.

It is on plastic systems that we will dwell in more detail. These drains are used much more often than metal ones, they have a pleasant appearance, and if the recommendations of the manufacturers are followed, they can be used for at least ten years.

But such operational properties can be expected only under one condition - it is made by a well-known and respectful company for its customers. How not to make a mistake with the choice, what to look for?

Tips for Choosing a Plastic Drainage System

This is an extremely important issue, it has a great impact not only on the durability of operation, but also on the installation technology. Before you buy a system, you should perform these steps.

1. Ask the seller to show documents of quality compliance. There is no need to ask for certificates, as most domestic buyers are used to, for our money we must demand a respectful attitude towards ourselves. Especially since the average cost of a plastic drainage system is approximately 30% of the total cost of roofing, which is a lot of money. The exact values ​​depend on the type of roofing materials, but for the most common budget roofs this ratio is maintained.

   

2. Carefully inspect the appearance of the elements of the system. If depressions are visible on the surface, then it is made of recycled plastic, worn out molds are used in production, or the technology is grossly violated. The most unpleasant option for consumers is made from recycled materials. This plastic has already served its purpose and has lost its original properties due to physical aging, intermolecular bonds have been significantly weakened due to harsh ultraviolet training. Unscrupulous manufacturers crushed it, added dyes and used it again in production. You need to know that such systems will certainly fall apart after a few years of operation.

   

3. Check the operation of the locking mechanisms. All connections must be made with maximum precision. The tolerance does not exceed tenths of a millimeter, this is the only way to guarantee the quality of the system, its tightness and stability. If individual elements fit into each other too easily, or vice versa, they can be pushed in with great effort, then this is a sign of a very poor quality of construction. You should not buy one, no matter how attractive the price. During installation, many complex and unforeseen situations will appear, in some cases serious mechanical breakdowns or critical damage are possible.

   

Conclusion. The better the system, the easier it is to install and the longer it will last.

Step-by-step instructions for installing a plastic drainage system

For example, we will consider the installation technology of one type of system from a well-known manufacturer. The name and brand do not matter, different types almost do not differ in the installation algorithm. For the production of work, you will need a hacksaw for metal, self-tapping screws of various lengths and diameters, a screwdriver, measuring tools, a bubble level, a chopping rope, a felt-tip pen, silicone spray.

Important. Some manufacturers allow installation of howl systems at sub-zero temperatures. Experienced builders categorically do not recommend listening to such advice; all plastic structures should be installed only at temperatures above + 5 ° C.

Step 1. Check the completeness of the system. The set should include the following items.

1. Gutter. It can have different diameters from 90 to 180mm. The size must be chosen taking into account the maximum amount of water, but for most cases a gutter with a diameter of 90–100 mm is used.

   

2. Bracket for fixing the gutter. At the time of purchase, determine the quantity based on a step of 60 cm.Add one more - it is better to provide a margin than to visit the store again later. Brackets can be metal (fixed to rafters and sheathing boards) or plastic (screwed to cornice boards).

   

3. Plugs. Installed at the ends of the gutters, can be on the left or right end.

   

4. receives water from the gutters and diverts it into pipes.

   

5. Gutter corners. Change the direction of the grooves.

   

   

6. Knees and corners. Connect several pipes into one, change their direction.

   

7. Pipe fixing brackets, fix them to the facade walls.

   

Step 2 Mark out the location of the drainage system on the house.

Marking the position of the funnel

During markup, several prerequisites must be met:

• the projection of the slope should pass over the upper edge of the gutter, the distance is ≈ 0–2 cm;
• the vertical projection of the edge of the slope should be located at a distance ≤ 1/3 of the width of the gutter from the axis of its symmetry;
• maximum distance between the first bracket and the water inlet ≤ 15cm.

Step 3 Attach the first end bracket to the cornice board. The holes of the bracket are elliptical in shape, which allows precise adjustment of the position of the element. Align it horizontally, the gutter should touch it with the entire surface, such contact reduces concentrated loads. And they are very afraid of plastic products.

Step 4 Attach the roof slope end bracket. During fixing, it is always necessary to maintain the slope of the gutter, otherwise water will stagnate in it, vegetation will grow over time, leaks will appear, etc. The slope should be ≈ 3mm per meter. If the length of the slope is 10 m, then the difference in height between the first and last bracket is approximately 3 cm. Long slopes must be divided into sections and several water inlets must be mounted. If this is not observed, then it will not be possible to withstand the projections of the slope and the upper edge of the gutter recommended above. Because of this, a large amount of rain and melt water will spill past the spillway system.

Step 5 Pull a rope between the installed brackets, it indicates the correct position of all the others.

After that, you can begin to collect the elements of the gutter, this is a very important task, work carefully. We must always remember that after the start of operation of the house, fixing problems with the drainage system is much more difficult than following the recommendations for proper installation.

Gutter Assembly

Important. To increase the tightness of the joints of the plastic drainage system, it is recommended to additionally seal them with a special silicone spray. It performs two functions.

1. Reduces friction between plastic and rubber during assembly. The insert is not damaged or displaced from its technological place.
2. After hardening, it additionally seals the connection and significantly improves the quality of the installation of the drain.

Step 1. Turn the chute upside down. Cut the gutter to length with a hacksaw.

Step 2 Install the gutter in the prepared brackets and funnel. Fix with special latches.

Important. Please note that the funnel is attached to the bottom of the whole gutter, and is not used as an independent load-bearing element. This engineering solution increases the reliability and durability of the structure.

Step 3 If the length of the gutter is insufficient, then it is necessary to use special connecting elements for lengthening. At the same time, a gap is always left to level the temperature linear expansions of the spillway system. The connecting elements have dashes, with their help the correct initial gap between the ends of the gutters is selected, taking into account the air temperature at which the installation is done.

Step 5 In the corner of the building, make a turn of the chute. Select an element based on its value. Always use a special silicone spray, responsible manufacturers implement it with the system.

Step 6 Install end caps.

Now you need to fix the vertical pipes.

Important. Never fix drainpipes close to the walls, always leave a gap of at least five centimeters. Otherwise, the surface of the wall will be constantly damp, a fungus may appear on it.

Pipe fastening

Step 1. Install the knee into the socket of the water inlet funnel, turn it in the desired direction and fix the position with a special self-tapping screw. If the distance from the end of the elbow to the wall is too large, then you will have to additionally insert a piece of pipe. It is cut off with an ordinary hacksaw or grinder from a standard pipe. The burrs need to be removed.

Step 2 Put on the second knee, with its help the vertical direction of the pipe is given. Attach the first bracket to the wall. Fastening can be dowels or self-tapping screws, choose the option depending on the characteristics of the facade walls. The first bracket should be no further than 15 cm from the knee.

Step 3 Pull the thread and mark the location of the remaining brackets along it. The latter is located near the drain to the ground, and the rest are symmetrical with a maximum step of 1.8 m.

Step 4 Fasten all the brackets in the drilled holes, assemble the pipe and fix it.

The first option is simple, cheap and more or less acceptable. The second option is long, expensive, but very effective.

What to choose - each developer decides individually. But it is much better to do this even at the stage of designing a house, especially if there is a desire to connect the spillway system to underground utilities.
