Radon Mitigation Through Depressurization: An Overview

We’ve written numerous articles here about the harmful effects of radon on your health and why it’s vitally important to get your home tested. If your test results uncover high levels of radon, what courses of action can you take to make your home safe? Radon mitigation is best achieved through depressurization of the soil under your home’s foundation. There are two principal methods of depressurization.

Sub-slab depressurization is the most common approach. A suction pipe (PVC pipe) is implanted through the floor slab into the soil beneath.  Depending on the type of soil, Radon Crew will assess the type of fan you will need to create a proper vacuum effect. The fan is then installed on the piping, outside of the living quarters, to push the radon up and above the roofline, where it is harmlessly dissipated into the air.

If, however, a drain tiling system around the foundation is present, active drain tile depressurization may be necessary. Here, radon gases collect in the drain tile itself, in the sump basin, or both. In that event, the sump is covered, creating an airtight seal. Next, a hole is cut and a pipe is installed into the sump basin to allow for the actual mitigation of the gas. Then, as with sub-slab depressurization, a fan is installed on the piping and vented above the roofline.
