The Humid-Evac addresses humidity and condensation by drying under the slab so that moisture cannot build up and enter the basement.
Independent research has shown that 80% of moisture in the basement originates from under the basement floor, and if the source of the dampness is addressed, 80% of the problem is eliminated. Drafting the air under the slab dehumidifies your basement in a far superior manner than any current method on the market. The Humid-Evac attacks dampness at the source.
