Basement & Radon Solutions installed a Sub-Slab mitigation system for Betsy & Russel in the basement. The radon suction line was installed in the left rear unfinished slab. After diagnostics for system performance, a 5 diameter hole was drilled through the concrete slab to the earth below. This is where a suction pit was then created. A 4″ schedule 40 PVC suction line was installed in the slab, sealed and will extend to the left rear exterior of the home. Then the radon fan was mounted on the left rear exterior of the home. The radon vent pipe was extended above the roof line to expel the gas safely. Then the Manometer gauge (homeowner radon fan monitoring vacuum gauge) was installed on the suction line pipe in the unfinished basement. After we installed the mitigation system the radon came down to 1.5pCi/L! It was a pleasure to help Betsy & Russel get their home ready for a new own and make it happy, healthy, and safe!”
