Radon Mitigation in Columbus, OH

Radon Mitigation in Columbus: local conditions

Columbus, OH sits on glacial till and expansive clay and has a humid continental climate with roughly 38–42" of precipitation a year. The local water table is moderate, and higher in low-lying and riverside neighborhoods, with significant winter freeze–thaw cycling, and a large share of homes have full basements. In practical terms, clay expansion and repeated winter freeze–thaw put steady lateral pressure on basement walls — which is exactly why radon mitigation is a common need here.
