When building a basement, you must make a waterproofing. Humidity adversely affects both the design and the foundation, and the products that are stored in the basement in winter. In such conditions, mold and other microorganisms grow. It is better to conduct waterproofing works in the process of building construction, but also the finished premise can be reliably protected from moisture.
There are several reasons for the occurrence of high humidity in the basement, such as the proximity of groundwater and the formation of condensation due to poor ventilation. To protect the structure it is possible to make internal and external waterproofing. Materials for external and internal works are resistant to different weather conditions.
For waterproofing indoors, membrane and penetrating formulations are often used. It is possible to make such protection independently, it is only necessary to prepare the surface in order to achieve good adhesion.
Penetrating compounds go deep into the surface of the walls and form a protective layer. This coating is reliable and durable, and the quality of the composition is determined by the depth of penetration of the mixture. The protective mixture displaces moisture from the pores of the surface and firmly adheres to it. The treatment with this component increases the strength of the material and forms a reliable waterproofing layer.
The membrane composition is a mixture which when applied to the surface forms a water repellent protective barrier. The coating repels moisture, but it is necessary to apply the compound on the prepared surface, the damaged wall needs to be reworked.
If it is necessary to protect the structures from groundwater, the depth of the source of moisture must first be determined. When finding a source at a depth of more than 3 meters, you can do with insignificant methods of protection.
The proximity of the water requires additional strengthening of the structure. The first layer consists of slurry, after which it is necessary to use mastic based on bitumen. The sludge must be applied in three protective layers, which will make it possible to exclude the penetration of water into the basement more reliably.
To protect the basement from rain, it is necessary to make a non-pressure waterproofing. The surface must be covered with a special mastic based on bitumen and polymer. This will be enough to create a water-repellent protective layer. To exclude the penetration of moisture through the capillaries, it is better to introduce a special solution by injection.
Thus, the passage through which water penetrates is clogged. This will also strengthen the material, but special equipment and skills are needed to carry out such work. Doing it yourself is very difficult.
The reliability of the waterproofing depends on all the factors considered and the sources of moisture. Sometimes it is enough to insulate pipes that form condensate and are the main cause of dampness. The approach of all communications must be reliably protected.
It is necessary to ensure good ventilation, which will significantly reduce the moisture content. Often, water leaks from the street, which occurs in the absence of or incorrect design of the sink. Rain water can wash away the foundation and penetrate into the basement. For reliability, external waterproofing will not hurt. Proper drainage and foundation coating with a bitumen-based mixture will reduce the risk of flooding.
It is possible to make waterproofing by oneself, modern waterproofing materials do not require special skills for their application. The main thing is to determine the source of moisture.
