Radon Mitigation in Fort Smith, AR

Radon Mitigation in Fort Smith: local conditions

Fort Smith, AR sits on clay soils, expansive in parts of the state and has a humid subtropical climate with about 50" of rain a year. The local water table is higher in the Delta and river bottoms, with mild-to-moderate winter freeze–thaw cycling, and slab and crawl-space foundations are common and basements less so. In practical terms, expansive clay and heavy rainfall drive foundation movement and moisture — which is exactly why radon mitigation is a common need here.
