How to deal with the resurgence of a cement floor in rainy season

There are two reasons why the cement floor is wet. 1 is that before the cement is poured, the waterproof layer of the floor is not ready or not ready, and there are cracks. This kind of cement floor with poor drainage layer is particularly susceptible to moisture, and there is no good way to solve it. 2. In rainy season, it rains and the sun comes out again. The air humidity is high and the outdoor temperature is relatively high, but the indoor temperature is low and the cement floor temperature is low, which will cause water vapor to condense on the cement floor and cause the cement floor to be wet. The solution to this problem is to open as few doors and windows as possible in rainy season, open the dehumidifying gear of air conditioner, and reduce the humidity of indoor air, thus reducing the humidity of cement floor.
