One Of The Four Sources Of Humidity In The Home（4）
The room turns to look down for the reason
Wet rooms generally appear on the first floor without a basement, or a basement with a lower foundation, and the other is the basement of a leapfrog recessed room or villa.As the summer season is wet and rainy, the groundwater level rises, and the groundwater soakens the exterior wall or the indoor ground, causing the indoor wall root (usually in the load-bearing wall) and some part of the floor to be wet or even seepage.In addition, if their own or upstairs or downstairs underground pipeline problems, it is also easy to cause moisture.
Most of the houses built after the 1990s have basements and semi-basements. If the houses are damp back, it is mainly because the external water seeps into the room from the root of the wall. After external treatment, the problem is not big.
