Radon Mitigation Photo Album: Basement Mitigation in Boise, ID

After recently moving into their Boise home, the homeowners wanted to address a radon issue identified during the inspection period. Testing showed an average basement radon level of 8.5 pCi/L. After reviewing the installation process and answering their questions, Idaho Radon designed an active sub-slab depressurization system with the suction point positioned near a center basement wall to maximize pressure field extension. The fan was installed on the exterior with the system vented above the roofline.   This 1940 home presented some interesting challenges, including limited fresh-air ventilation, a basement floor that appeared to have been placed in two separate concrete pours, and uncertainty about the material beneath the slab. Despite these conditions, the completed system produced excellent results, reducing the average radon level from 8.5 pCi/L to just 0.9 pCi/L.
