Radon Mitigation in Hattiesburg, MS

Radon Mitigation in Hattiesburg: local conditions

Hattiesburg, MS sits on highly expansive Yazoo clay and has a humid subtropical climate with about 56" of rain a year. The local water table is high in the Delta and low-lying areas, with mild winter freeze–thaw cycling, and slab and crawl-space foundations dominate and basements are rare. In practical terms, Yazoo expansive clay is a notorious cause of foundation movement here — which is exactly why radon mitigation is a common need here.
