Waterproofing of the basement from the inside from groundwater

The construction of the basement is a responsible and very serious process. Since this room is underground, it is most susceptible to the effects of groundwater, which, with improperly equipped waterproofing, can lead not only to the development of mold and fungus in the basement, but also to its flooding. We will consider how to make waterproofing the basement from the inside further.

Waterproofing of the basement from the inside - functional features

A very responsible mission, the protection of the basement from meltwater is relied on the waterproofing of the foundation. If moisture penetrates the basement, then the reinforcement will be destroyed, which under the influence of moisture will be covered with corrosion, then the foundation will begin to collapse. And this is the main part of the building, which takes on the entire load.

There are two types of waterproofing of the basement:

• internal;
• outer.

Each of these types is distinguished by a special technology of arrangement, which, in no case, cannot be violated. Since the safety and life of the whole house directly depends on the correctness of the manufacture of waterproofing.

Also, too high the basement humidity contributes to the propagation of the fungus and mold in it, which, when stored in the basement of products, leads to their damage.

Please note that the connection between external and internal waterproofing is very thin, and in case of violation of one of them, moisture will certainly fall into the basement. Since the main function of external waterproofing is to protect the basement from moisture from the inside, for example, as a result of precipitation atmospheric. Internal waterproofing protects the basement from groundwater.

Waterproofing of the basement from the inside from groundwater: restoration of the existing room

The waterproofing work of an internal nature in the basement should be carried out even in the process of laying the foundation of the house. However, it happens that the previously built basement must be waterproofed, as well as rid of mold and excess moisture.

Before starting work, the basement should be inspected. Start, from its external part, the blind area should be of high quality, moisture should not seep through it. In addition, near the basement, the presence of a drainage system is required, which removes moisture from the entire building.

If external waterproofing is in perfect order, but moisture is still present in the basement, the internal waterproofing of the basement should be taken.

In order to waterproof the basement, the following actions should be performed:

• examination and strengthening of a blind area, not only near the basement, but around the entire building;
• detection of sources through which moisture enters the basement;
• preparation of the foundation for sealing seams and cracks;
• waterproofing work;
• ensuring filter waterproofing of the basement;
• arrangement of the ventilation system.

To perform internal waterproofing in the basement, first of all, work is carried out to determine the depth of groundwater. This value will help determine the method of protecting the foundation from moisture, if the water lies below the basement, then it is enough to waterproof only walls, otherwise, it is necessary to provide high -quality protection of the floor from moisture.

Characteristic of penetrating waterproofing of the basement from the inside

Before starting work, the basement should be prepared. Application of penetrating waterproofing is possible only if the concrete, which processed walls, ceiling and floor, has not yet frozen.

In order to perform penetrating waterproofing of the basement, it is necessary to use a solution based on sand, cement and additional inclusions, such as chemically active substances.

It is these substances that are able to penetrate deep into the basement, I form the so -called crystals that do not let water.

Please note that the principle of penetrating waterproofing is to form a substance in the form of hydrophobic crystals that do not allow water to enter concrete.

In addition, concrete acquires the characteristics of frost resistance and resistance before corrosion. Due to the fact that this method is environmentally friendly, its use in the basements in which food products are located is possible.

Penetrating waterproofing is divided into several varieties in relation to the depth of its penetration and the application method. The basement waterproofing from the inside with a penetron is a fairly common option, since this material provides reliable and economical protection of the basement from moisture.

For example, a brush or spatula is used to apply a hydroxy, a given substance can penetrate deeper into concrete, more than 8 cm. Consider that applying this waterproofing is possible only if the concrete is still wet.

Teling waterproofing technology from the inside

The need to arrange internal waterproofing in the basement is caused by the following reasons:

• the complete absence or need to repair the old waterproofing system in a wooden house;
• non -high -quality waterproofing;
• Building a new basement.

The waterproofing of the basement from the inside from groundwater materials distinguish three types:

• coating option;
• asphalt type;
• Enough type.

The first option is a liquid type of protection, for its implementation, it is necessary to coat the walls and the foundation from the inside along the inner layer. For these purposes, the presence of a solution is required, which is based on a liquid bitumen or a specialized emulsion, which contains certain additives.

In the coating of waterproofing, two subspecies are distinguished:

• staining;
• penetration.

The first option implies the application of a special layer on the walls, covering them and still providing their protection against moisture. A film is formed on the surface through which moisture is not able to fall into the basement. To make staining, the compositions are based on which ethinolen resin lies. The composition of the composition is carried out in three layers, the thickness of each of which is at least 5 mm.

To improve the quality of waterproofing of the coating type, it is recommended after drying it, apply clay to the walls. The thickness of the layer is 40-50 mm.

The most popular option is the use of special mastics for which a brush or spatula is used. To get mastic in the cracks and inaccessible places, the method of its filling is used.

No less popular option is the waterproofing of the basement from the inside with liquid glass.

Among the advantages of this method, it should be noted:

• Due to the fact that the surface is crystallized, the material fills all pores, the resistance of concrete improves before abrasion and mechanical influences;
• There is zero moisture absorption on the surface, thus increases the service life of the basement itself;
• If necessary, in protecting the decorative coating, liquid glass copes with this problem - perfectly.

Before using liquid glass as a waterproofing of the basement, it is recommended to dilute it using ordinary water in a ratio of one to two. After applying liquid glass, the surface is covered with a hard and strong film, which is characterized by moisture resistance, stability before mold, fungus and various kinds of biological organisms.

Another option for performing internal waterproofing of the basement is the use of asphalt waterproofing. The essence of this method is to apply a 15 mm layer of asphalt to the sexual coating of the basement. There are two types of such waterproofing:

• cold;
• hot.

The first option differs in less high cost, and the second - with better performance characteristics. If you plan to use asphalt on a wooden floor, then a hot method is preferable, since such asphalt can penetrate more deeply into wooden pores.

The glow of waterproofing is based on the use of various kinds of roll materials. For their laying on the surface, mastic is used. Most often, materials are used in the form of roofing material, isola or waterproof. Before laying them, careful priming of the walls is required. This type of waterproofing is most often installed on the base covered with cement screed.

Laying of roller material is carried out on the surface of an excess. The number of layers is affected by the type and depth of groundwater in relation to the basement. If hot mastic is used, then it is laid in a layer of about two millimeters, and if it is cold, then one millimeter.

If roller materials are glued on a bitumen surface, then before these, it is covered with a primer that improves adhesion.

Hard waterproofing of basements from the inside with your own hands

Of particular complexity is the implementation of waterproofing using this technology. First, the plaster mixture is made, which contains only cement, sand and water. This composition needs to be processed both the walls and the floor with the ceiling in the basement.

For these purposes, you will need a waterproof cement or special impurities, on a sealing basis. This protection option is the most reliable, despite the complexity of work.

To perform waterproofing the basement from the inside and the entire room, be guided by the instructions:

1. Make a hole on the floor of the basement, size of 30 cm. Pour the pillow from the sand half of the pit.

2. Next, pour the surface with a concrete solution with a thickness of about 100 mm. The option of independent preparation of concrete solution or its purchase at the factory is possible. The second option is more reliable, since this type of concrete has a higher quality.

3. A bitumen base of three layers is applied to the base. The frequency of their application is calculated taking into account the complete drying of the previous layer.

4. Near the walls it is necessary to dig ditches, each width of up to 100 cm. In them, it is also necessary to equip a pillow of sand. Next, pour everything with a concrete solution and apply a bitumen coating.

5. On the walls, it is also necessary to apply a bitumen impregnation in three layers. Further, the walls are coated with clay, and the thickness of the layer is about 50 cm.

Waterproofing technology using liquid glass

Among the materials for waterproofing the basement from the inside, liquid glass is particularly popular due to its environmental safety and excellent performance.

We will talk about technology and recommendations for applying liquid glass further:

1. Application of liquid glass is carried out on the inner surface of the walls. Before that, the walls should be carefully aligned and degreased. To ensure superficial absorption of concrete on internal plaster, it is recommended to use the composition of the spray gun in the process.

2. The depth of the penetration of liquid glass into the wall is no more than two millimeters. If necessary, in deep impregnation, the composition is applied to several layers, in which case, the depth of penetration increases to two centimeters.

3. If, it is planned to apply liquid glass to wooden areas, then the technology changes slightly. To ensure reliable protection, wooden objects are dipped in liquid glass.

4. In addition, liquid glass allows waterproofing of any other surfaces. Since this material has anti -corrosion properties.

5. Before applying liquid glass, it is thoroughly mixed. For work, it is recommended to use a brush or roller. The instructions for liquid glass clearly indicate the proportion of its breeding, in accordance with a particular sphere of use.

6. Before applying the composition, you should clean the surface of dust, dirt, mold or fungus, if any. To prepare wooden structures for applying the composition, sandpaper is used.

7. Another method of waterproofing the basement with liquid glass, involves the dilution of liquid glass with a cement mortar, until a homogeneous consistency. After drying, you get an excellent protection of the basement from moisture.

8. The proportion of mixing liquid glass and concrete solution is one to ten. Keep in mind that all work is carried out quickly enough, since the composition has a high setting speed.
