Moisture will also often get through the foundation. If in the compounds of the foundation with the wall poor waterproofing, then along the same cracks the water will get inside the wall. The walls and the foundation are protected from the outside. Penetrating materials are used for this. This type of waterproofing acts inside the walls, clogging cracks and channels. Moisture access is thus stopped, and the wall will be clean and dry all year round.
