Radon Mitigation in Birmingham, AL

Radon Mitigation in Birmingham: local conditions

Birmingham, AL sits on red clay and expansive Black Belt clay and has a humid subtropical climate with about 56" of rain a year. The local water table is high in low-lying and coastal areas, with mild winter freeze–thaw cycling, and slab and crawl-space foundations dominate and basements are rare. In practical terms, expansive clay and very high rainfall drive foundation movement and crawl-space moisture — which is exactly why radon mitigation is a common need here.
