Waterproof, mainly to prevent water from permeating the floor or walls of the room.Basement waterproof, the key is to choose good waterproof materials in the early decoration, and pay attention to the quality assurance of construction, from the external wall, internal wall to the ground, waterproof treatment in all directions, to avoid water penetration.

In fact, waterproof is not equal to moistureproof, basement humidity is more important because the moisture of the ambient air is too high, moistureproof is mainly aimed at the air humidity.
The water evaporates into the air, which increases the humidity.The ventilation system of the basement is generally poor, and there is no sunshine, so the moisture stays in the basement and continues to increase, leading to the high relative humidity of the space.Under the action of the moisture pressure for a long time, it will lead to the foaming of the waterproof coating layer, falling off, causing structural damage and aggravating the humidity of the space.
