How do I prevent moisture in my basement floor?
Plastic drainage mats, or dimple mats, allow air to circulate under the flooring and provide a moisture barrier.
They also provide an insulating layer of air that separates the floor from cold concrete, reducing the potential for moisture damage from condensation or water vapor migrating through the concrete..
Why do they put plastic under concrete?
The sand layer cannot dry downwards by vapor diffusion because of the plastic sheet—it is a vapor barrier after all. In fact that’s why we have it under the slab. … ** We want to prevent water vapor from coming up from the ground into the concrete slab.
Can I pour concrete directly on dirt?

Can mold grow under vinyl flooring on concrete?

Why is my concrete floor wet?

Spread out each plastic square flat over a dry area of concrete. Tape along all four edges of the square with duct tape or other waterproof tape. Firmly press the tape to create a moisture-tight seal with the plastic and concrete. Use as many squares as needed to test all the main areas that may get flooring.
Will a dehumidifier in the basement help the whole house?
