Radon gas mitigation

A mitigation system is the best way to reduce excessive radon concentrations in a building.

Active soil depressurization is the most effective mitigation technique. The most common method for a building with a concrete slab on a subbase of gravel involves installing a pipe crossing the slab in the basement and attaching a fan to it to evacuate the radon outside. 

For a crawl space the possible techniques vary depending on the presence or not of compacted earth or a concrete slab with or without a gravel subbase, but essentially the corrective involves a negative pressure system. A secondary benefit when treating a crawl space for radon is to provide an effective solution to moisture problems that may be affecting the space, thereby improving the health of the building and its occupants.
