About the Radon Mitigation Process

Radon Mitigation Process - The most common approach is a “Sub Slab Depressurization” or Active Soil Depressurization (ASD) system, which uses a fan and PVC pipe to draw soil gasses from below the basement floor and then release it above the roof. The radon fan creates a vacuum under the basement floor drawing soil gasses out before the get into the house.

When a stable slab is not present we encapsulate the soils with a robust vapor barrier. A 6 mil cross-scrimmed poly is secured to all exterior walls creating a sealed environment that we then deploy our conventional fan/pipe system. (Radon Mitigation Process)

When option #1 & #2 are not viable utilizing a Heat Recovery Ventilator (HRV) can address the problem. HRV’s remove radon ladened air and introduce fresh outdoor air. “The solution is dilution”. On a cold winter day the heated indoor air is run through the unit transferring the heat energy into a radiator core. At the same time the cold outdoor air runs through the radiator and is warned. The result is fresh cooler air being introduced into the home. HRV’s are not a “first-Tier” solution because they are expensive and have both heating and cooling impacts on the indoor air environment. Warmer-Summer & Cooler-Winter. (Radon Mitigation Process)
