Radon Mitigation in Charleston, WV

Radon Mitigation in Charleston: local conditions

Charleston, WV sits on clay and shale on steep terrain and has a humid climate with about 44–48" of precipitation a year. The local water table is variable, with steep slopes concentrating runoff, with moderate-to-significant winter freeze–thaw cycling, and a mix of basements and hillside foundations. In practical terms, steep-slope runoff, landslide-prone ground and heavy rain stress foundations — which is exactly why radon mitigation is a common need here.
