Waterproofing of basement walls
Usually the problem of waterproofing becomesrelevant in the offseason, when the water table reaches the highest level, which can become a very unpleasant surprise for many house owners in the form of water in the basement. The waterproofing of the walls of the cellar traditionally begins with a diagnosis of the reasons why the water is there. The main causes of dampness can be: wrong past waterproofing or complete absence of it, incorrect technology of materials application or insufficient level of their quality.
A damp basement causesfunctional room. There is always a high level of humidity, condensation and mold on the walls, as well as unpleasant smells of mold and dampness. In the damp cellar, products are not stored, since they are affected by mold. Is it possible to turn it into a functional premise again, which the owner will use for his needs? Can. It is important to determine the reasons for the appearance of dampness, as well as apply the appropriate materials that will help to clear the room from water penetration.
If the waterproofing of the basement walls is broken, then theremay appear damp. The room may be located above or below groundwater level, respectively, the repair work should be carried out depending on this. The methods of waterproofing can differ only by the choice of materials that are offered in the market, and also by their quality. And the correct technology is only one.
Waterproofing of the basement walls should be done infull, if its floor is located below the water level. If this level is high, then in the basement can simply stand water. It appears through the cracks in the floor and walls, in this situation we are talking about a fairly high groundwater pressure. Work should be carried out with the correct selection of appropriate materials. Waterproofing of walls of cellars in this case should be carried out by qualified specialists. The technological chain of work includes such important stages:
- Carrying out land works to excavate the soil along the perimeter of the basement, which needs waterproofing (outside);
- cleaning of external walls from dirt;
- carrying out of repair works of external basement walls, thus vertical and horizontal waterproofing of walls should be restored.
After that it is required to lay drainage onthe outer perimeter of the basement, it will allow you to rapidly remove thawed and storm water from the walls. Drainage systems should be laid along the entire perimeter of the building, which will ensure a better result.
In the basement there are several of the weakestplaces - corner joints of the floor and walls. In most cases, just through these places, the penetration of groundwater is noticeable. Before starting the internal waterproofing, it is necessary to pump the water out of the basement, if it is there.
Waterproofing of the walls of the cellar impliesrestoration of vertical and horizontal waterproofing. The first type of work should be carried out using penetrating and lubricating insulating materials. Horizontal waterproofing is carried out above the level of water with the use of penetrating materials pumped into walls under pressure through pits drilled in a certain order. This type of work requires a high qualification of a specialist, since it requires the use of special equipment. Horizontal waterproofing is rightfully considered the most difficult stage of work.
Correct execution of all necessary work in theThe basement guarantees you that there will no longer appear dampness and water. Otherwise it will be necessary to conduct the whole complex of works again, which is not only tedious, but also very costly.
