The Basement Premises and the Choices on Wet Basement Repair

How to be if you already need to enter the premises in operation? There is an exit. This is the use of sanitizing plasters. They are also otherwise called restoration, salt accumulation, dewatering, and renovation. The term “rehabilitation” means in Latin treatment, restoration. The main producers are German enterprises, which in 1985 developed and successfully introduced them. They were intended for the restoration of architectural structures, later their range of application was significantly expanded. For the Wet basement repair this is essential.

The principal distinguishing feature of these plasters is a high porosity (about 45%) and excellent water vapor permeability. They work as follows. The first thin and non-continuous adhesive layer serves as a strong adhesion between the base layer and the wall surface. The main layer (usually 15–25 mm) performs work on the evaporation of water and the accumulation in its pores of salt crystals, which are always contained in water. Sometimes another layer is used leveling. Moisture from the wall does not reach the surface, which means that wet spots will not show up or efflorescence can be seen. The wall will continue to dry without external moisture. It remains to remember to remove the evaporated moisture by organizing ventilation or airing. Premises can begin to use as intended.

Waterproofing of the basement with sanitizing plasters

The surface plastered in this way can be painted, but the requirements for compatibility and high vapor permeability are imposed on paints. Silicate paints, for example, meet these requirements. In any case, it is necessary to carefully study the instructions for the use of sanitizing plasters and not to violate its recommendations. It is allowed to use such plasters without waiting for the walls of the basements to be drained, and this is the main, but not the only advantage. Some manufacturers still limit the amount of permissible wall moisture.

  • The disadvantages include the relatively high price of sanitizing plasters. Do not forget that such plasters are cumulative. This means that their lifespan is limited by the volume of pores that can accumulate salt crystals. In turn, the rate of salt accumulation depends on the degree of mineralization of surface groundwater and the volume of evaporated moisture. If the entry of new capillary moisture into the walls is not blocked, sooner or later we should expect the return of the old problem of “wet walls”.

Water in the basement will appear if you do not waterproof the foundation in time and correctly. It may be a little, only that the walls are damp, and maybe so that the puddles on the floor. It depends on how much moisture “overboard”. Regarding the Leaky basement repair this is essential.
