HOUSE WATERPROOFING

Waterproofing provides reliable protection of any construction projects and structural elements from the penetration and harmful effects of water. The roof is one of the most common objects for the use of waterproofing materials, however, when building a high-quality modern structure, it is important to ensure waterproofing not only of the roof, but also of the foundation, walls, and floor. It is mandatory to use waterproofing in underground or basement rooms, where it is necessary to provide protection against the influx of water from the surface of the soil, as well as from the penetration of groundwater.

DRAINAGE OF FOUNDATION AND HOUSE

Drainage systems serve to force water away from the insulated surface and work in conjunction with high-quality waterproofing. When installing foundation drainage water is discharged to a safe distance from the structure, or to a specially organized collector system. Drainage is used in construction areas with high humidity, high groundwater levels, in residential basements, and when installing.

WATERPROOFING AND DRAINAGE DEVICE

Modern waterproofing materials and drainage membranes make it possible to fully provide comprehensive protection of the structure in accordance with regulatory requirements and the necessary technical parameters. Unfortunately, when installing waterproofing and drainage, current standards and manufacturers’ recommendations are not always observed; chemically incompatible materials are often installed together, which entails additional costs for constant repairs and their replacement. Poor waterproofing of wooden materials leads to gradual destruction, rotting, the formation of fungus and mold, leading to damage to furniture, finishing materials and expensive equipment. In addition, the general microclimate of the house suffers.

The installation of waterproofing must be carried out very carefully, since it must last for a very long time, and water, as a rule, has an extremely destructive effect on the structure. The main properties of high-quality waterproofing material are waterproofness, strength, heat resistance, elasticity, resistance to aggressive environments, strong winds and strong water pressures. In each construction segment, it is necessary to select a certain type of waterproofing materials, depending on the properties and purpose of the room, taking into account the compatibility of the materials with the structure. In our climate, we always recommend using drainage when there are basement floors.

WATERPROOFING THE FOUNDATION

When building a high-quality modern structure, it is important to ensure waterproofing not only of the roof, but also of the foundation, walls, and floor. It is mandatory to use waterproofing in underground or basement rooms, where it is necessary to provide protection against the influx of water from the surface of the soil, as well as from the penetration of groundwater. Modern waterproofing materials and drainage membranes make it possible to fully provide comprehensive protection of the structure in accordance with regulatory requirements and the necessary technical parameters. The statistics are sad - more than 50% of modern buildings with basements are leaking. The reason for this is insufficient attention to waterproofing buried parts and drainage, the use of outdated materials and schemes, non-compliance with current standards and manufacturers' recommendations, and the use of chemically and mechanically incompatible materials. Fortunately, modern waterproofing materials and drainage membranes make it possible not only to fully ensure comprehensive protection of the structure in accordance with regulatory requirements and the necessary technical parameters, but also to significantly save the construction budget compared to outdated schemes.

FOUNDATION DRAINAGE

To protect the underground part of structures from water, it is necessary to carry out a set of measures consisting of waterproofing (including protection from damage), insulation and drainage of the foundation. This is especially important if the site has a high groundwater level, the soil consists mainly of clay, and the soil freezes to great depths in winter.

With excess humidity and temperature changes, the soil increases in volume and becomes mobile. This process is called "heaving". At the same time, heaving forces can be so large that not every foundation is able to compensate for them without damage, and since the foundation of a house is one of the most critical building structures and the destruction of the foundation can lead to problems throughout the building, it is necessary to keep the soil in a stable condition for depth of soil freezing. High-quality foundation drainage allows you to remove moisture and prevent soil heaving, as well as protect against groundwater and prevent flooding of the base or foundation, which, if there is a basement, will prevent moisture from entering the premises.

Work on foundation drainage is carried out both during new construction and during reconstruction and repair of building foundations. Moreover, the cost of work during the construction of a new house is less than the cost of repairing the foundation, so high-quality work and the use of high-quality modern building materials allow you to avoid high costs during further operation.

TRADITIONAL METHOD OF FOUNDATION DRAINAGE

Fig. 1. Diagram of the traditional drainage system.

The traditional drainage system is a closed system of perforated pipes, which are installed with a slope under the foundation itself in a layer of crushed stone. The water that collects in the drainage pipes flows to the lowest point and forms a collection well, and is then discharged outside the site. At the same time, the list of work performed is very impressive: excavation of soil up to 2 meters from the wall, and to a considerable depth, waterproofing of the foundation, geotextiles, replacement of part of the soil near the wall with clay, perforated drainage pipes in geotextiles, crushed stone in geotextiles, sand, backfill, blind area . At the same time, the need to remove and transport large masses of soil greatly affects the cost of work. It is almost impossible to do such work without the involvement of equipment and specialists. You also need to take into account the risk of damage to the waterproofing coating when backfilling.

FOUNDATION DRAINAGE USING PROFILED DELTA MEMBRANES.

The use of Delta drainage membranes allows, compared to the traditional method of foundation drainage, to significantly save money and improve the quality and reliability of the drainage design due to:

Significant reduction in the volume of excavation work;

Reducing costs for crushed stone, sand;

Reduced installation time.

Drainage membranes are profiled plates covered with a durable layer of high-strength geotextile. Water from the soil freely penetrates through the geotextile and flows down the profile to the drainage pipe, thus reliably cutting off moisture from the foundation. In addition, in this scheme, the drainage membrane serves as reliable protection of the waterproofing from damage by hard soil fractions - stones, etc.

With this technology, by reducing the width of the trench and significantly reducing the amount of drainage backfill materials (sand, crushed stone), both the cost of excavation work (which currently constitutes the main cost part of the budget for drainage and foundation waterproofing) and the amount of removed soil are significantly reduced. and delivered drainage fill. In addition, there is no need to use an additional layer of geotextile separating the drainage layers. An approximate comparison of the estimated cost of installing traditional drainage and foundation drainage using the Delta drainage membrane can be .

Conclusion: The use of Delta profiled membranes allows you to save over 30% on the work performed and building materials, while the speed of work performed is higher, and the quality of Delta materials produced in Germany allows you to have no doubt about the reliability of the entire system.

Membrane PLANTER geo as part of a foundation waterproofing protection system is capable of:

• Ensure effective drainage. Up to 5 liters of water per square meter. This is more effective than sand and crushed stone! Reducing water pressure helps minimize the risk of leakage;
• Reduce the cost of work by replacing sand with backfill soil;
• Provide reliable protection of waterproofing from mechanical damage;
• Protect waterproofing from root growth;
• Promote protection from chemical exposure to aggressive external environments;
• Extend the service life of the system as a whole by organizing the most comfortable conditions for the waterproofing layer.

PLANTER waterproofing protection and drainage system:

1. Technoelast EPP, laid in two layers;
2. Bitumen primer TECHNONICOL No. 01;
3. Profiled membrane PLANTER geo;
4. Foundation wall;
5. Drainage pipe;
6. Transitional side (fillet);
7. Engineering training;
8. PVC waterstop;
9. Backfill soil.

When the groundwater level is high, even the most first-class waterproofing can quickly fail due to the constant and high pressure of the liquid accumulated near the foundation. In this case PLANTER– the best solution not only for protection, but also for effective water drainage.

Waterproofing when backfilling

Groundwater disposal or drainage is one of the most important challenges faced by many basement projects built in areas with high groundwater levels. The second, no less important task is how to protect the waterproofing from mechanical damage during backfilling. After all, these works are the most common cause of damage to the waterproofing layer, since this soil can contain various hard and sharp objects.

Builders and architects of the last century solved these and many other problems in complex and often labor-intensive ways. For example, they replaced the backfill soil with sand or used crushed stone in combination with brickwork, which acted as protection for the waterproofing layer. Some, less advanced and economical engineers, did without everything, but subsequently the problem could only be solved in a radical way - digging up the foundation and doing the work from scratch.

It was like that before. New technologies offer a completely affordable material that can solve the above problems + give the system a number of positive properties that will help increase its service life. The name of this material is PLANTER geo.

Drainage PLANTER geo

PLANTER geo– profiled membrane made of high-density polyethylene with thermally bonded geotextile. Simply put, it is an extremely durable and at the same time flexible material with protrusions (spikes) over the entire area. Geotextiles are specially attached to the spikes, which allows you to filter water.

How does this work, you ask? The system is incredibly simple. Let's consider the most popular option without insulation:

Waterproofing is applied to the foundation. A protective membrane is attached to it PLANTER geo, geotextile to the ground. Space appears between the geotextile and the base of the membrane thanks to the spikes. A special drainage pipe is installed at the base of the foundation, which “receives” water from PLANTER geo and directs it to special places for subsequent diversion. More detailed instructions that will answer many questions are presented in the adjacent “installation” tab.

* To calculate the cost of services for waterproofing the foundation of a building, you need to know such key parameters as: the depth of the foundation, as well as its perimeter. Using this data, the square footage of the foundation walls is calculated, and the cost of their waterproofing is calculated, taking into account the work you need. It is also easy to calculate earthworks if the third indicator, the trench width, is taken as a constant of 1 meter (the minimum trench width for this type of work).

A set of measures to protect underground premises from dampness from foundation waterproofing and wall drainage is applied only if internal finishing is planned in these premises. Otherwise, you can get by with one wall foundation drainage (if the object is under construction and the foundation pit has not yet been filled in) or ring foundation drainage(if the object has already been built and a blind area has been made around it).

In a set of measures to protect underground premises from dampness, foundation waterproofing performs two main functions:

• protection of interior decoration;
• protection of concrete foundation structures from penetration into them and the negative influence of groundwater.

Alone, without wall drainage, foundation waterproofing will not be able to cope with these tasks - well, only if for a very short period of time (no more than a year). And certainly without wall drainage of the foundation it will not cope with flooding of the underground room. This is due to the fact that wall drainage of the foundation relieves the powerful capillary pressure of underground water on the basement or ground floor (especially during periods of flood or heavy, prolonged rains).

Foundation waterproofing is a system that, according to SNiPs, consists of:

These are the basic principles of the foundation waterproofing system. If you decide to install foundation waterproofing yourself, you will definitely come across a huge number of nuances associated with the arrangement of various components, such as: pairing horizontal foundation waterproofing with vertical, installing a side between the slab and the foundation wall, arranging the upper edge of the foundation waterproofing, connecting a geomembrane with wall drainage, etc. Therefore, entrust it to the professionals - our practical experience consists of about a hundred installed foundation waterproofing systems, and our competitive prices will pleasantly surprise you.

The proximity of groundwater or significant accumulation of moisture in the soil negatively affects buildings, especially the foundation. To eliminate excess moisture, you need to take a number of actions related to the installation of a drainage system.

Here are the main reasons why a building requires foundation drainage:

• when the basement is located below the groundwater level or less than 50 cm to it;
• if the house is built on clay soil;
• if the place where the building stands is an area of ​​capillary moisture.

Foundation ring drainage

If it is necessary to protect a structure (foundation) that does not have a basement floor or a building that is erected on heaving soils from water, then ring drainage is used. As a rule, it is performed at a distance of 0.8 to 3 meters from the foundation walls, behind the blind area.

The foundation drainage system is based on tubular drains, which are installed along the contour of the supporting structure. The principle of operation of the device is to reduce the groundwater level in the protected circuit, thereby significantly reducing the risk of flooding of underground buildings.

The depth to which the drains will be laid in relation to groundwater depends on how much their level will decrease. Considering the fact that the laying of ring pipes is carried out at a certain access from the building, this can be done after the completion of construction work.

The device of a ring drainage makes sense if it is made no higher than the depth of soil freezing, otherwise the system will not cope with the tasks assigned to it.

Cost of turnkey foundation ring drainage (price per meter)

The amount that ring foundation drainage will cost depends on several factors, so the price is determined individually:

• depth of the building foundation;
• the perimeter of the building, taking into account the distance from the wall.

The cost will also be affected by the timing and location of the project.

Wall foundation drainage

Wall drainage of the foundation of a house is done in a number of cases:

• when installing basement floors at a height of no higher than 50 cm above the groundwater level; when placing buried parts of the house below the calculated groundwater level; when building a house on clay and loamy soils; when the house is located in the area of ​​capillary humidification and preventing the appearance of dampness in the room ;
• when constructing a technical basement in clay soils when buried more than 1.3 meters from the surface of the earth.

The distance between the drainage pipe and the wall of the building depends on the width of the foundation and the location of inspection wells. The drain material is selected based on the depth of their installation and taking into account the aggressiveness of groundwater.

The cost of turnkey foundation wall drainage (price per meter)

When ordering foundation drainage, the customer is primarily interested in the cost of the service. PSK "InzhStroyIzolyatsiya" can provide only basic prices for arranging drainage for the foundation of a house, and the price is indicated per linear meter. The total amount is formed taking into account the following factors:

• scope of work;
• soil type;
• drainage material used;
• deadlines.

Types of foundation drainage depending on the design

The main purpose of arranging drainage for the foundation of a private house is to protect the structure from moisture entering the basement. Proper installation of the system will prevent flooding of the basement, keeping the foundation dry.

Foundation drainage work is possible both during the construction of a house and in an existing building. The type of system will depend on the type of foundation itself and other factors:

• location of the site - hill or lowland;
• soil type;
• depth of groundwater;
• type of house foundation;
• relief features;
• frequency of precipitation.

And if in one case a simple storm sewer will be enough, then in another it is necessary to install a full-fledged drainage device for the foundation and surrounding soil.

With basement or ground floor

In most cases, the basement of the house is planned to be used as a functional area - boiler rooms, saunas, gyms, even living rooms are located there. That is why they need to be protected as much as possible from groundwater flooding.

For basements and basements, the complex of foundation drainage works includes wall drainage and then high-quality waterproofing of the structure. These measures must be carried out together, since individually they do not solve the problem.

With strip foundation

If the building is erected on a strip foundation, then work on drainage of the foundation will be aimed at preventing the following problems - mobility of the foundation during soil heaving and moisture penetration into the concrete structure.

In this case, a ring drainage is performed, which will drain water from the building and relieve lateral soil pressure.

Grillage or slab on stilts or just a slab

In this case, draining the foundation of the house is an optional procedure. It is advisable to do this in the case when the house is located on clay soil and the owner simply wants to be on the safe side. The only thing you need to remember is that if the slab is mounted on piles, they must be located below the freezing point of the soil in order to prevent the building from moving.

How drainage work is performed

Turnkey foundation drainage includes a set of works to protect the building from contact with groundwater. It is made in the form of a closed system of pipes located at a certain angle below the level of the base of the very foundation of the house. The pipes are connected to each other by special wells to drain water.

If you need high-quality foundation drainage, it is recommended to use wear-resistant two-layer corrugated pipes with a diameter of up to 110 mm for effective water drainage; the price of the work practically does not depend on the selected material.

The complexity of drainage arrangement directly depends on the type of soil, the terrain on which the building stands and the depth of groundwater.

Before laying pipes, it is necessary to carry out a set of measures in stages.

1. Excavation of the foundation. The outer part of the foundation is thoroughly cleaned of soil, the old waterproofing layer is removed and the foundation is left to dry.
2. Treating the outer part of the foundation with a primer based on bitumen and kerosene.
3. After drying, treat the base with moisture-resistant bitumen mastic. It is recommended to fix a special painting mesh into the finished layer of mastic.
4. After complete drying, another layer of mastic is applied.

Then the next stage of work is when the foundation is drained on a turn-key basis and the necessary materials are prepared (the price directly depends on their quality). The process of setting up the system is as follows.

1. The building is surrounded by a trench along its entire perimeter at a distance of 1.5 meters from the foundation. All work is carried out taking into account the highest point. The width of the trench should be at least 35 centimeters greater than the width of the pipes.
2. To install rotary wells at the outer corners, special extensions are made.
3. A sand layer 25 centimeters thick is poured onto the bottom and thoroughly compacted.
4. The next stage is laying geotextiles so that the edges protrude beyond the edges of the trench and backfilling with coarse gravel with a layer of up to 20 cm.
5. Next is the installation of drainage pipes, maintaining a slight slope relative to the lowest point of the system. Bends for rotary wells are fixed at turns.
6. Installation of a well for pumping water. This is done at a depth of up to 60 centimeters, the bottom of the pit is necessarily covered with geotextiles, and only then a plastic tank with perforated walls is installed.
7. All pipes are brought to the collection tank at an angle, then covered with crushed stone. The ends of the geotextile are connected and secured with special clamps.

It is very important that after laying the pipes, the drainage is carefully covered with a sand cushion and a layer of turf. Each stage is very important, because a properly designed system will be able to maintain optimal humidity in the area and reliably protect the house from flooding.
