The cause of increased dampness is poor waterproofing of the basement or foundation, the flow of pipes or poor ventilation. In this case, its traces will appear at the bottom of the wall and on the floor next to it, there may even be whitish traces. Then the waterproofing must be strengthened, and maybe put it again. But this is a way out for those who live in a private house, residents of high -rise buildings should turn to their housing and communal services.
