If the house is built on wet lands, where groundwater is coming close to the surface of the earth, it is necessary to use the waterproofing of the basement. If this is not done, groundwater will rise and gather in the basement, creating an unnecessary pool. Water will rise in the form of condensate throughout the structure, increasing humidity and destroying the buildings, as well as interfering with the repair of communications that pass through the basement. An integral part of all this process will be the formation of mold and fungi. Correcting this state of affairs is very difficult, problematic and entails high cost of repair work. It is better to provide waterproofing for the basement immediately, starting construction. In new buildings, the basement waterproofing is carried out on the outer walls, and in old buildings, the waterproofing of the walls is made from the inside.
The first step in the diving of water from the site may be hydromeliorate work. Next, waterproofing of the basement of the basement with roll materials, penetrating or coating mixtures, is used. Coating mixture for waterproofing can be prepared for use or dry. It is applied to clean, even and slightly wet walls of the basement. The moisture content of the basement walls is needed so that the mixture does not immediately penetrate the concrete, and, drying, does not crack. There are mixtures that have a better chemical reaction with a mixture with water. For waterproofing the basement of the basement, the coating mixture is applied to 4 times. And each layer is applied to the dried layer of the previous layer.
Penetrating waterproofing is also applied in the same way, but in this case the basement walls should be well dried and cleaned of dust. Penetrating waterproofing should get as deep as possible into the basement walls, to form a protective layer. In the reaction with the surface, the smallest crystals are formed, which protect the basement walls from groundwater. The surface of such waterproofing withstands the constant pressure of groundwater.
Roll waterproofing is used less often. It is applied on the outside of the walls of the basement in two layers. At the same time, it must be heated by burners, and it is extremely neat, that not damage the protective layer of waterproofing.
Horizontal waterproofing is the waterproofing of the basement floors. It is also performed using penetrating mixtures. You can also apply cast waterproofing for the basement floor. This is more complicated, requires experience in work. Since this technology uses bitumen materials. And for applying bitumen, it must be heated to a temperature of 100-120 ° C.. We need special devices, and accuracy in work. But this is the most durable and reliable waterproofing. Its service life, subject to manufacturing technology, is equal to the service life of the construction itself.
But not only underground waters threaten the basement, it can be meltwater, rainwater, and pipelines. To do this, you need to make drainage and drainage systems. Monitor their condition and carry out repairs in time. Otherwise, work on re -waterproofing will require huge costs, and the opening of the soil around the buildings.
