At Floorguard®, we understand the damage that excess moisture creates for concrete flooring. Floating floors are in our opinion the best and safest type of flooring to use in these types of situations. However, we also very strongly recommend installing a plastic vapor barrier on the walls and floors, as moisture can easily pass through the dirt and create a humid space. 2 Benefits of concrete placed directly on vapor retarder/barrier—Research has demonstrated that concrete specimens isolated from a moisture source at the bottom of the specimen dry faster than specimens exposed to water or water vapor at the bottom (Brewer 1965). vapor barrier under concrete slab My architect recommended a 10 mil sheet of poly under the slab as a vapor barrier. Your choice on the opposite end of the spectrum is to cover the concrete with the most open and permeable carpet and permeable underlayment.

Moisture builds up and has nowhere to go.
