Our Solution to Moisture, Dampness, and Odor Problems
According to the University of Minnesota … “An active sub-slab depressurization system including a washed-rock layer below the slab is recommended. This draws moist air from beneath the slab and may help to reduce the amount of moisture vapor that enters the home through openings in the slab. It also assists in controlling radon and other soil gases. Sumps and other open connections to the soil outside the foundation and below the slab should be blocked and sealed.” (full article here)
Subslab soil exhaust systems installed by Standard Water Control tie into the existing drain tile system, then exhaust beyond the roof with an inline fan which draws the moisture and soil gases out from underneath your home. The Standard Water Control subslab soil exhaust system includes installing seals on the sump pump basket system cover; a known entry point for moisture and such.
