Drainage systems in a summer cottage: surface drainage. Do-it-yourself surface drainage of a site Is it necessary to install drainage in a garden or summer cottage

from 1000 rub. m p.

The bulk of land plots in the Moscow region are subject to flooding and groundwater to varying degrees. Heavy loamy and clayey soils, along with heavy rainfall in our region, create extremely unfavorable conditions for growing both garden and ornamental plants. Excess moisture destroys elements landscape design, sharply reduces the life of the building, negatively affecting its foundation. Normalization water balance land plot it is impossible to imagine without creating an effective drainage system.

A well-calculated and professionally equipped drainage system ensures the removal of melt and rainwater from the surface layers of the soil and at the same time sharply reduces the level groundwater in its lower layers. Thanks to this, in areas with proper drainage, puddles disappear much faster than on neighboring ones; moving around the site becomes more comfortable; the plants are not oppressed and delight their owners with rich greenery and rich harvests.

When should you think about installing surface drainage for a site?

the site is located in a low-lying area in relation to neighboring landholdings;
predominates on the site clay soil or a water-resistant clay horizon lies close to the surface;
there is a pond nearby;
the site is located in an area of heavy flood waters;
on summer cottage high groundwater level;
Along the perimeter of the site there are neighboring foundations and concrete buildings.

Types of jobs

Everyone wants the drainage system on their site to be inexpensive, durable and easy to use. Let's talk about systems and technical solutions, which combine these important components.

What needs to be done to prevent the drainage system from becoming an expensive extravagance? Is capital deep drainage really necessary on the site? Surface drainage system "Alta-profile" - a simple answer to difficult questions. Let's get acquainted with their features in more detail, but first, a little useful theory.

Do you need drainage on your garden plot?

The structure of the soils prevailing in the Russian Federation is such that rain and melt water do not have time to pass through them as quickly as necessary to maintain water balance. As a result, moisture accumulates in upper layers soil, which leads to waterlogging. The consequences of such an imbalance are inevitable:

excess moisture in winter period leads to frost heaving of soils, and, as a consequence, to the destruction of blind areas, foundations, pedestrian paths and other solid structures;
cultivated plants, whose roots are in waterlogged soil, gradually stop bearing fruit and ultimately die;
a basement or cellar, once flooded with groundwater, will also bring few pleasant moments into the everyday life of the inhabitants of a country house.

Conclusion: the need for a drainage system on the site is a fact. But what should this system be? How large will the construction work be? Let's answer these and other questions.

What should be an inexpensive but effective drainage system?

Deep drainage is a complex system underground communications that collect and drain moisture from the site into special wells, collectors or reservoirs. Deep drainage where there is a high groundwater level, that is, not everywhere. If the area is of limited size, if only the foundation and the space adjacent to it need to be protected from surface runoff, then there is no need for expensive deep drainage.

Small ones are very beneficial in terms of creating drainage systems. personal plots. As practice shows, for their maintenance, ordinary surface drainage is sufficient, which is both simpler and cheaper deep systems.

Let's take, for example, the surface drainage systems "Alta-Profile", which effectively remove melt water, precipitation and others from the territory. surface runoff. Such drainage is used even in areas with high groundwater levels. What is noteworthy is that after installing surface drainage, the need to install expensive deep systems quite often disappears by itself. In any case, surface drainage can always be supplemented with deep drainage, if, of course, the need arises.

So, an objective understanding of your needs helps you save significantly on the construction of a drainage system. For example, if a drainage system is needed solely to protect the foundation and the surrounding area, then by organizing the simplest surface drainage, you will perfectly solve the problem of drainage. However, each specific case requires separate consideration.

Also, the prospect of saving directly depends on the cost of components for the drainage system. Any drainage is a collection of channels, protective grilles and receiving points, which are made of metal, concrete or plastic. Sometimes there is a mixture of concrete and polymers.

Types of drainage systems based on material of manufacture

Concrete systems are massive, expensive and fragile. They are appropriate in general civil and industrial construction: when improving streets, sidewalks, etc. Polymer concrete drainage systems also fall into this category.

An alternative to concrete systems is metal systems. They are also expensive and not very practical: over time, the protective coating of the metal is destroyed and corrosion destroys everything that mechanical influences did not have time to destroy. As a result, after several years of intensive use, the working modules of the system will need to be completely replaced.

Plastic is also used for the manufacture of drainage systems - an inexpensive and durable material that is light, practical and resistant to aggressive chemical influences. Many people underestimate the power of plastic, but is there any reason to doubt it?

Entertaining physics

The first question of a person who first heard about plastic drainage systems is: how will such drainage behave when severe frosts? Will water that freezes in the working modules during the sudden onset of cold weather break its lines, storm water inlets and sand traps? Many people think about this, but not everyone thinks of the simplest experience from a school physics course. Let's remember: there are two bottles with plain water– plastic and glass. Which one will burst after immersion in freezer, and which one is guaranteed to withstand several cycles of freezing and thawing?

Plastic drainage behaves in the cold like a plastic bottle: elastic polymers retain their structure, regardless of climatic factors. There have also been no recorded cases of plastic drainage being destroyed by acids or, for example, petroleum products (gasoline, machine oil, etc.). Strength plastic gratings sufficient to support a passenger car, while the weight of the system is so small that its transportation, installation and maintenance turn into a pleasant chore for the buyer.

If your choice fell on plastic drainage (namely, it is the most promising option for private construction), please note: although plastic systems are cheap, they are by no means free. Not a single manufacturer of truly high-quality and durable systems will sell their products for pennies. On the contrary, the reasonable cost of high-quality goods is always higher than, for example, that of counterfeit goods.

Complete set of surface drainage systems Alta-Profile

Currently, the manufacturer produces two types of surface drainage systems:

Point drainage systems - are precipitation collection points installed in places where rapid drainage is required large quantity water.
Linear drainage systems – designed to collect surface waters from large areas: from the blind area around the house, from sidewalks and adjacent areas, etc.

Very often these solutions are used separately, but the efficiency of surface drainage will increase significantly if linear and point drainage are combined into one combined system.

Point drainage

Point drainage is a system consisting of buried storm water inlets, as well as auxiliary elements (protective grilles, dampers, storm water inlet superstructures, etc.). Water collection and drainage points are organized nearby roof gutters and terraces, on areas in front of the entrance to the house and near pedestrian paths. Also, the installation of storm water inlets would be appropriate in places where there are natural and man-made depressions in the landscape.

Linear drainage

Linear drainage is a system consisting of trays, sand traps and additional elements(sand catcher baskets, gratings, grating fastenings, etc.). The trays are covered with decorative grilles (plastic or metal), which protect the system from debris. The main function of the trays is to collect and drain wastewater into sand traps.

Linear trays that collect water from large areas are installed in the ground at a horizontal slope. By combining trays of different depths, you can build a system with a fairly high throughput.

Trays linear systems installed near construction areas, sidewalks and functional areas. They are designed to drain water from large areas.

Both systems, through the side exits of sand traps and storm water inlets, communicate both with each other and with underground drainage mains. Underground pipes, in turn, carry wastewater outside the site.

Sequence of installation work

Installation of a combined system (linear + point drainage) is carried out in the following order:

Identification of areas and areas that need to install gutters and storm water inlets first.
Preparation of trenches for installation of drainage trays and underground pipes.
Creation of recesses for rainwater inlets and sand traps.
Installation of working elements of the system on the prepared “cushion” and pouring concrete.

Requirements for earthen trenches:

trenches for installing surface trays and underground pipes must have a horizontal slope (2-3 cm per 1 m);
the depth of the trench intended for installing the drainage tray must be such that the tray is immersed in the ground 5 cm below the surface of the earth, taking into account the prepared cushion;
the trench profile must correspond to the size of the tray and have some margin for concrete curling.

The trays are installed in the trench on the prepared concrete base, after which they are covered with a decorative lattice and poured on the sides concrete mixture. This technology allows you to protect the tray from mechanical influences and deformations that may occur due to soil shrinkage. The same principle applies to the installation of rainwater inlets and sand traps.

As you can see, there is nothing difficult about installing surface drainage with your own hands. For those who know how to use construction tool- This is a good way to save money on arranging a functional drainage system.

Let's sum it up

Surface drainage prevents soil from being washed out from under foundations and other capital structures, makes the site neat and aesthetic, while at the same time protecting it from surface runoff of any origin. The construction of surface systems in most cases eliminates the need for the developer to install expensive deep drainage. This fact, even without complex mathematical calculations, allows the developer to evaluate the beneficial prospects of using surface systems.

Now - more specifically. Plastic drainage systems "Alta-profile" are:

tangible savings on construction work, as well as on the purchase of components (if you purchase them from the manufacturer);
Possibility of year-round operation in all conditions climatic conditions(confirmed by successful product testing in northern latitudes and beyond the Arctic Circle);
ease of maintenance and unpretentious operation (the working modules of the system can be easily opened, washed and cleaned of debris);
durability (the guaranteed service life of the Alta-Profile drainage system is 25 years).

The grids, trays and working modules of the system can easily withstand pedestrian loads as well as weight passenger cars. In other words, Alta-Profile plastic systems have all the characteristics that meet the interests of 99% of private developers.

Surface drainage- a common method of drainage in areas with close groundwater, which can lead to waterlogging of the territory, in places where it is necessary to remove rain, melt and other excess (for example, at a car wash) moisture.

Point and linear drainage

There are two main principles of surface drainage: point and linear. Point drainage is used to collect local water sources, the purpose of linear drainage is to organize the collection of excess water from a large area. The most rational is a combination of these two systems. This allows you to reduce the length of channels storm sewer and reduce the volume of excavation work.

Point drainage

For organization point drainage such devices are used as: rain inlets, drainage systems, ladders, storm flaps.

Linear drainage

Linear drainage It is a system of buried channels and sand traps (containers in which sand and small debris carried out by the water flow are retained). From above they are closed with removable protective and decorative grilles. Such grilles prevent debris and leaves from entering the system and ensure the safety of pedestrians and vehicles. Drainage channels usually made of materials such as concrete, polymer concrete, plastic (PVC, HDPE, polypropylene)).

Linear drainage device requires preliminary preparation surfaces. In accordance with the instructions of some manufacturers, point drainage devices must be mounted on a concrete base. If the installation technology is followed, the main load should fall on the closing grille, which is selected depending on the load class required bandwidth and design of the surrounding landscape. Additionally, flat slopes can be prepared on one or both sides of the drainage line. At correct execution task, the likelihood of soil subsidence is reduced, the length of storm drainage channels is reduced, and the catchment area is increased, since water is collected along flat slopes into a system of lined drainage canals. Through a system of vertical and horizontal outlets, the linear drainage system is usually connected to the storm sewer.

Surface drainage
Surface drainage Surface drainage is a common method of drainage in areas with close groundwater, which can lead to waterlogging of the territory, in places

Is it possible to arrange surface drainage of a site with your own hands? In swampy areas with high groundwater there is a constant danger of flooding. Clay layers do not allow water to quietly go deep and it flows under the surface of the soil. Underground currents destroy the foundations of buildings, wash away roads, fences, fences. Are damaged root systems trees. This especially applies to fruit trees and berry bushes.

Surface drainage is useless in this case, since it does not destroy the clay layers deep in the soil. To drain wetlands, three to five meter drainage ditches are needed, several kilometers long. This is how the famous peat bogs near St. Petersburg were drained.

When does shallow drainage make sense?

If your site is located in a place where groundwater is higher than a meter below the soil level, surface reclamation does not make the slightest sense.

In what cases can surface reclamation bring real benefits?

If the site is located at some elevation, but in some places there are puddles and stagnant water. Water accumulates in the center of the site or on the paths; the water from the roof drain does not leave, but tries to turn into a small swamp. Most likely, under the sand layer there is a clay layer that prevents the free flow of water. Surface storm drainage can really solve the problem and prevent waterlogging. Proper ring drainage around the foundation will also help.

Problems of soil drying out in arid areas

Surface stormwater additionally solves problems that are relevant in arid regions. Such as salting out the soil. Stagnation of water provokes the leaching of salts from solid rocks into fertile layers.

Evaporation of moisture naturally, through the pores of the earth and loosening leads to the formation of a hard mineral crust on the surface, which is subsequently quite difficult to turn into fertile soil.

Open water mains, is it necessary to carry out excavation work?

Differences surface drainage is that it can be done in open form. In this case, the water runs through drainage gutters arranged at a slope into a specially dug drainage well. Gutters are manufactured industrially and can be made of any waterproof and durable material. The most common types are plastic and ceramic gutters. The top of the surface storm drain can be covered with special gratings. Sand traps are usually installed in drainage areas.

The depth of drainage ditches for surface storm drainage usually does not exceed 50 cm. However, for effective drainage operations, full-scale excavation work should not be neglected.

If stagnant, storm water can be no less destructive to the foundation than groundwater.

The difference from deep storm drainage is that the depth of the ditches is 1.5 meters, and from 60 to 30 cm. If the soil is not strengthened using drainage ditches, the surface elements will not be able to perform their functions and will be displaced by storm flows. The water will not end up in the wells, but simply on the ground, which will again lead to puddles that won’t dry out, etc.

What is a stormwater drainage well?

A sump well is a hole about 3 meters deep with waterproofing walls, but without a bottom. A layer of coarse gravel is poured onto the bottom. An inspection hatch is installed on top, which is needed to access storm sewer pipes, if any. In this case, it is through the inspection hatches that the storm sewer is flushed. If there are no pipes, you can fill the gravel to the top and cover it with turf.

Gravel performs a filtering function and cleans wastewater, the depth of the well must be sufficient to destroy the upper layers of clay. It is necessary to wash the gravel on average once every 5 years or if the system has become noticeably worse.

Other options for organizing wastewater

Often the role of a settling well for storm water is played by a small pond located on the site. To set up a pond you need to buy a special container, they come in different shapes and even with different levels of depth. To install the pond, a pit is dug with a calculation of +20 cm in all parameters and a sand cushion is installed. This is necessary for better shrinkage of the garden pond. Photos of garden ponds, including those with unpretentious fish, such as carp, can be viewed on fishing websites. Although carp in such ponds are usually quickly tamed and even eaten from hands. Water from the pond can be used for irrigation. Additionally, purified water from the septic tank is discharged into the fish pond.

Surface drainage

Purpose

Surface drainage is the most important condition to protect the foundation of buildings, basement (underground) and basement premises, as well as the territory of the site from excess moisture. For drainage installation, a project is being developed that determines the location of drains, their depth, design, slopes, installation of channel slopes, selection of components and materials, and the possibility of interfacing individual elements drainage system. The most effective combination of surface and deep drainage.

Types and principles of surface drainage

Point and linear drainage

There are two main principles of surface drainage: point and linear. Point drainage is used to collect local water sources, the purpose of linear drainage is to organize the collection of excess water from a large area. The most rational is a combination of these two systems. This makes it possible to reduce the length of storm drainage channels and reduce the volume of excavation work.

Point drainage

Point drainage is used for local collection of rain and melt water. Spot drainage devices are installed under drains, in door pits, under watering taps and in other places where local water collection is necessary. In addition, a point drainage system can complement a linear drainage system in places where fast and efficient drainage from the surface is required (entrances, platforms, paths in front of the house, terraces).

To organize point drainage, devices such as rainwater inlets, drainage systems, ladders, and storm flaps are used.

Linear drainage

Linear drainage It is a system of buried channels and sand traps (containers in which sand and small debris carried out by the water flow are retained). They are closed from above with removable protective and decorative grilles. Such grilles prevent debris and leaves from entering the system and ensure the safety of pedestrians and vehicles. Drainage channels are usually made of materials such as concrete, polymer concrete, plastic (PVC, HDPE, polypropylene)).

The linear drainage device requires preliminary surface preparation. In accordance with the instructions of some manufacturers, point drainage devices must be mounted on a concrete base. If the installation technology is followed, the main load should fall on the closing grille, which is selected depending on the load class, the required throughput and the design of the surrounding landscape. Additionally, flat slopes can be prepared on one or both sides of the drainage line. When the task is performed correctly, the likelihood of soil subsidence is reduced, the length of storm drainage channels is reduced, and the catchment area is increased, since water is collected along flat slopes into a system of lined drainage channels. Through a system of vertical and horizontal outlets, the linear drainage system is usually connected to the storm sewer.

Biodrainage ditches (Bioswales) are biological systems cleaning from sediments and pollution using marsh plants.

In particular, biodrainage is used near parking lots. Rainwater flows into biodrainage ditches that filter wastewater and discharge it to the groundwater level without soil erosion. Moisture-loving plants are planted among the stones, which absorb moisture and filter polluted water.

Surface drainage
Surface drainage Surface drainage is a common method of drainage in areas with close groundwater, which can lead to waterlogging of the territory, in places

During the season of high rainfall, the soil receives water in excess. Water stagnates near buildings. This serves to create serious problems. Excess moisture causes: flooding of basements, destruction of the foundation, erosion of the upper layers of soil. And on land plots the root systems of plants rot.

Surface drainage maintains foundation integrity

Purpose of the drainage system

The surface drainage system is capable of performing its functions in any area of the ground. Its necessary location is where water stagnates in the upper layers of the soil. This leads to various problems. The main ones are related to the destruction of the integrity of the foundations of buildings and the flooding of the basement floors of buildings. Possible also: deterioration of soil quality, damage doorways, soil washout, etc.

Do-it-yourself drainage of the site is carried out based on the combination of schematic nodes. These are: catch basins, trenches and drainage points. The structural features of the structure differ depending on its type. Choice of surface drainage from 2 modern solutions the problem of excess moisture, linear and point, consists of the personal desire of the owner of the site, as well as the complexity of using a particular system in the required location.

If you make the drainage yourself, the linear view will take more time to design. The design features of such drainage make it possible to remove moisture not only from the building, but also from vehicle access points and pedestrian paths. The point view serves as a means of a narrower purpose.

Point type drainage

Point drainage is designed to collect excess water in places where it accumulates the most in one small area. Excellent for drainage from the roof of buildings, drainage of thresholds front door and drainage at the street water supply unit. Surface linear drainage is a reservoir for collecting water. It performs a function drain hole, only has the shape of a box made of plastic or concrete.

For the beauty of the area, the drainage can be decorated

Such a system can work either independently or as an appendage to the linear type. A raincoat is a vessel equipped with places for water drainage. Made from concrete and plastic. As an additional filter from debris, special baskets are installed in it. Their presence simplifies the maintenance of the device and helps protect the drain system from possible clogging. Once you have taken care of installing the water seal, you can remove bad smell from stagnant waters.

The drain ladder is an important part of the point system. It serves as a connecting unit with the pipes of the linear collector or with the sewer outlet. The presence of a damper allows you to perform a safety function against the reverse flow of water.

Linear type drainage

This type of drainage is a more complex system in design. It requires the combined use of gutters to capture water throughout the area where it is used. The drainage gutter is installed along pedestrian roads, buildings and along their contours, if necessary. Water collectors are placed at a slight angle. This avoids stagnation of water and facilitates its rapid removal. The gutter is made from various materials.

The use of plastic and concrete to produce these linear drainage units is popular. On top of it they place decorative grilles. Filters - sand traps - are installed in the pipes at a certain distance. All of the above elements are the main components of a linear drainage system.

The location for this type of drainage is suitable if:

There is a large relief slope of more than 3 degrees.
It is necessary to remove moisture from buildings.
It is necessary to drain water from the slope.
At at different levels location of buildings and utility area.
For drainage of pedestrian areas.

Such a drainage system has all the necessary properties for quickly draining a large volume of water.

Linear drainage system around the house

Such a system can protect the foundation of a building from flooding along its entire perimeter. Surface drainage around the house is designed based on those structural units that are available to you for use. The best option The solution for water intake is the presence of perforated plastic pipes. You can do the drainage yourself.

Linear drainage system protects the foundation along the entire perimeter

The construction of linear drainage along the walls of the house occurs in stages and is carried out as follows:

Mark a place for the pipes at a distance of 40-60 cm from the walls.
Trenches are being dug. Their depth should be equal to the diameter of the pipe with a margin for the layer of substrate, soil and setting the required angle.
A substrate of gravel and sand is laid at the bottom of the trench.
Pre-prepared pipes are laid and connected, taking into account the drainage of water to the required distance from the house.
Work is underway to decorate the drainage areas.

As noted earlier, it is easy to connect point drainage systems to such a system. Sharing Such devices increase the efficiency of the entire system and will help protect your home from excess moisture in the soil.

Application of open drainage on the site

Drains are also installed on land plots. By using open drainage in the right place, you can relieve the soil of unnecessary stress caused by a large amount of moisture in the soil. This device is made by hand and does not require special skills. A trench is dug on the outskirts of the land plot so that one wall is beveled at an angle of 30-40 degrees. The depth of the dug hole is made at least 0.6 meters. Width from 0.5 m. During heavy rainfall, the ditch will show its performance.

The wastewater along the beveled edge will gradually fill the hole. This is especially noticeable in the first month of spring, when the air temperature rises and the groundwater level rises. When the land plot is located on a slope, excess water is discharged faster. The ditch is located at its lower points, where water constantly accumulates. In such places, the formation of a swampy ground level is possible, so the use of open drainage in this place- necessity. The dug holes are connected and directed outside the site.

A professional approach to the use of earthworks to prepare open drainage lies in the use of special equipment.

It is necessary to use devices for studying soil topography. These are a level and a range finder. The last tool is especially convenient due to its design features. If it is not possible to use them, then it is necessary to carefully examine the area and draw up corresponding map in the form of a sketch of the site. Monitoring water flows during rainfall is also included in the survey plans. Having sketched out all the nuances, the locations of the drainage ditches are calculated and the digging work begins.

Application of drainage open type is effective method solving the problems of stagnation and oversaturation of soil with water, which does not require financial investments. There are also disadvantages to devices of this kind. This is a violation of the decor of the land and other facts. Such ditches are dangerous for pets and children who may accidentally get into them. Therefore, this type of drainage system is inferior in quality to closed drainage. Its design consists of a pipe system large diameter, up to 110 mm, which are covered with soil from above and it is completely safe to be in such areas.

Features of surface drainage
Surface drainage is a special drainage system that allows you to remove accumulated moisture to a certain distance from buildings, thereby maintaining the integrity of the foundation.

To prevent the formation of waterlogging areas around a residential building, surface drainage is performed. Surface drainage consists of special structures (modular channels), piping, making it possible to lower the level of groundwater and groundwater pressure. Water is collected from the site, paths and platforms, roofing, and open terraces. Depending on the method of moisture collection, removal is carried out: Point - for local collection of rain and melt water into door pits. It is mounted under drainage systems equipped for collecting water from the roof.In the form of a drainage main for the disposal of atmospheric precipitation over a large area. A system of in-depth trays, gutters, sand traps which, like drains, must be cleaned periodically. The gutters and containers that retain sand are covered with cast iron or metal gratings.

As a rule, the greatest effect is achieved when a comprehensive drainage scheme is used: point and linear. If the soil on the site is sandy and well-drained, the site itself is located high, the groundwater level is 1.5 m or even lower, you can use only surface drainage without installing deep drainage.

Surface drainage of the site.

Surface drainage of the site is the simplest and cheap way cope with excess moisture in a specific area. Surface drainage of a site begins with an inspection of the site and at the same time drawing up a diagram of the location of the trenches. Typically it includes main ditches around the perimeter and additional ones in places where water accumulates. The depth of the ditch is up to 70 cm, the width is up to half a meter. The walls are made with a bevel of 30 degrees. Additional trenches relative to the main ones are made with a slope towards the collecting tank. The bottom of the trenches can be covered with a 10-centimeter layer of sand - it must be compacted tightly. Next, trays are laid and covered with sand traps. To give such structures a presentable appearance, fit them organically into the overall landscape solution territory and protect it from large debris; the top is covered with grates. If wastewater is discharged to sewerage treatment, then the volume of the receiving septic tank must take into account such a load, especially in terms of the magnitude of the salvo discharge. A team of professionals will complete surface drainage of the site in one day, including excavation and installation of structural elements.

Surface drainage around the house.

Surface drainage of the site is intended for the accumulation and removal of upstream flow at a depth of up to 0.7 m. To collect and remove waters with an increased level of groundwater level or those that exceed it during peak periods, surface drainage of the site is also done to a depth of more than 1.5 m, which is below the soil freezing mark. The area is drained, which makes it comfortable to be in the green zone of the site. Green plantings do not rot due to waterlogging of the roots.

Open water drainage operates only in the warm season. Freezing of the layer-by-layer soil “pie” stops the action. It resumes only after thawing. To carry out work, it is imperative to inspect the area allocated for management in advance. land area: find out the source of excess moisture, soil characteristics and develop a project detailed diagram installation of all links of the drainage chain, indicate the water standing points, proposals for its disposal. Surface drainage of the site will be effective only if the right approach to its arrangement.

Surface drainage cost.

The preliminary price will differ for surface drainage: the final price will be determined after all measurements. The cost of surface drainage directly depends on: area of the site and its vertical orientation,type of soil pie and groundwater,distance of the object from the material base construction company Andwork on landscaping after installation.

Knowing these initial parameters, the total length of the drainage route is calculated. It is assumed that 1 l.m. Drenov collects water from 10 square meters. area of “problem” (clay, loamy) areas. From 11-15 sq.m. – for sandy loam and sandy soil. Surface drainage - installation cost - can be increased with additional payment for related work:dismantling of fundamental structures that impede the arrangement of drainage,disposal of excavated soil from the site,arrangement of storm drains andcable connection, etc.

Turnkey surface drainage in optimal option executions can be performed professionally and with a guarantee only by specialists. They evaluate turnkey surface drainage for each linear meter.

The system must be designed taking into account the calculated load. Its value depends on the specifics of the soil, its saturation with water, the degree of filtration at different times of the year, and the amount of water absorbed. Accurate calculations by specialists will determine the adequacy of plastic lattice elements and polymer pipes. If the loads increase, such materials will not withstand them; metal gratings will have to be used. Correct arrangement provides concrete wells and gutters, channels.

Drainage of the site is carried out only after signing the contract and approving the estimate. From this moment, all work, from drawing up a project, carrying out calculations, to putting the facility into operation, passes to the executing company. This standard list includes: soil survey,approval of the drainage project andterrain analysis.Laying of drainage (pipes, trays, storm water inlets) is carried out in accordance with GOST R ISO 14001.

Turnkey surface drainage is recalculated at a lower or higher cost if its depth differs from the catalog value.

Schedule for calculating the cost of surface drainage of a site.

Example for surface drainage: We have a plot of 15 acres that needs to be drained. We look at the length shown above, we get 150 meters.The price per linear meter of surface drainage is 1,400 rubles. We multiply the length of the drainage by the number of acres and get an amount of 210,000 rubles. If there are no options for water drainage, then you need to install a collector well with a pump costing 30,000 rubles. Total turnkey RUB 240,000.

Make surface drainage of the area.

SNiP 3.05.04-85 will help to make surface drainage of the site according to all the rules. They give the depths, main dimensions, pipe materials, installation methods, without which it is impossible to make surface drainage of the area. The following work algorithm will help to arrange a linear type of drainage system.

- Divide the area into equal segments.
- Dig narrow trenches approximately 0.5 m deep (it all depends on the terrain and slope requirements) towards the main flow of water.
- Cover the bottom with a small layer of sand (0.1 m).
- Trays are installed and secured with stones on both sides.
- The joints are filled with concrete mixture for sealing.
- Free space between the walls of the trench and trays it is filled with soil or crushed stone.
- The backfill is compacted.
- If necessary, the required slope is achieved for that part of the site that borders the linear highway. The discharge efficiency will increase if the surface is asphalted or covered with concrete.
- The drainage network is connected to the general system.
- On top part water intake grates are installed in the trenches.

If you need to make surface drainage of an area by connecting the channels at an angle, they are sawed hand saw with a diamond disk, capturing both of its walls in the tray at once.

Surface drainage around the house is one of the elements of general drainage from the site. With the SoftRock rubble-free system you can organize effective removal moisture from the foundation of residential and commercial buildings, eliminate basement flooding, and significantly reduce soil erosion. Compared with traditional systems where a layer of crushed stone is applied, SoftRock significantly reduces financial costs and reduces installation time. Surface drainage of the site is 50% more efficient using Softrock drainage blocks. Installation is so simple that you can do it yourself.

Application of surface drainage

Surface water drainage will help solve many problems:

drainage of water from the foundation of residential and commercial buildings in order to protect against shrinkage, the appearance of unsightly damp spots, mold, mildew, and basement flooding;
removing moisture from footpaths and parking areas;
avoiding saturation of the soil with water, followed by frost heaving and squeezing of the building from the ground;
reduction of cracking of the soil surface;
reducing the processes of erosion and washout of the fertile layer from the site;
on the site, surface drainage prevents septic tanks from exiting cesspools;
reducing the occurrence of aggressive chemical compounds due to the interaction of moisture with salts contained in the soil;
maintaining the attractive appearance of the site and the general landscape of the territory.

Regardless of the soil composition and surface topography, drainage must be installed for any area.

Advantages of the SoftRock system

Most effective option is a system of surface drainage of the site using Softrock drainage blocks. It has numerous advantages compared to traditional analogues using a crushed stone layer:

light weight of the blocks, making it possible to install the system without the use of equipment;
