Radon Mitigation in Denver, CO

Radon Mitigation in Denver: local conditions

Denver, CO sits on highly expansive bentonite and clay soils and has a semi-arid climate with about 15–20" of precipitation a year. The local water table is generally low, but expansive soils move sharply with moisture, with significant winter freeze–thaw cycling, and full basements are standard along the Front Range. In practical terms, expansive bentonite clay is a notorious cause of heaving and foundation damage here — which is exactly why radon mitigation is a common need here.
