Radon Mitigation in Fresno, CA

Radon Mitigation in Fresno: local conditions

Fresno, CA sits on widespread expansive clay soils and has a varied climate with wet winters and dry summers across much of the state. The local water table is variable by region, with minimal winter freeze–thaw cycling in most areas, and slab-on-grade dominates and basements are uncommon. In practical terms, expansive clay and seismic movement are the main foundation concerns — which is exactly why radon mitigation is a common need here.
