Radon Mitigation Photo Album: Sub Slab Depressurization in McCall, ID
This home was constructed using Insulated Concrete Form (ICF) blocks. The homeowner incorporated a 12-inch base of 3/4” aggregate beneath the slab, which significantly enhanced sub-slab air communication. As a result, our radon mitigation system performed exceptionally well, reducing indoor radon levels to 0.3 pCi/L.
