Basement & Radon Solutions, BRS Pros, did this by intalling a Sub-Slab Exterior Radon Mitigation System. This sysem will suck the radon gas from the slab under the basement before it reaches the home. We started by drilling a 5 diameter hole through the concrete slab to the earth below where the suction pit was created. A 4″ schedule 40 PVC suction line was installed in the slab, then sealed and will extend to the left exterior of the home. The radon fan was mounted on the left exterior, and the radon vent pipe was extend above the roof line to safely get rid of the radon gas. We also installed a manometer gauge (homeowner radon fan monitoring vacuum gauge) so the tenant can make sure the system is still working. By installing the mitigation system we brought the radon down to 0.8pCi/L! It was a pleasure to help Pro Guard Property Services to make this home happy, healthy, and safe!”
