Waterproofing of basement walls

Usually the problem of waterproofing becomes relevant in the off-season, 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 the diagnosis of the reasons why the water is there. The main causes of dampness can be: the wrong past waterproofing or complete absence of it, the wrong technology of using materials or insufficient level of their quality.

A damp basement causes the loss of a very functional 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 to apply the appropriate materials that will help to save the room from water penetration.

If the waterproofing of the walls of the basement is broken, then there may appear dampness. The room may be located above or below groundwater level, respectively, the repair work must be carried out depending on it. 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 walls of the basement should be carried out in full, 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 cracks in the floor and walls, in this situation we are talking about a fairly high groundwater pressure. Work should be conducted with the correct selection of relevant materials. Waterproofing of cellar walls 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 this, it is required to lay drainage along the outer perimeter of the basement, it will allow quickly to 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 itself there are several weak points - 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 basement walls means the restoration of vertical and horizontal waterproofing. The first type of work should be carried out using penetrating and lubricating insulating materials. Horizontal waterproofing is performed above the water level using 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.

Proper execution of all necessary works in the basement guarantees to 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.
