Basement & Radon Solutions installed a Sub-Slab Exterior mitigation system for Stephanie. The radon suction line was installed in the left front end of the basement slab. After diagnostics for system performance, a 5″ diameter hole was drilled through the concrete slab to the earth below. This is where the suction pit was then created. A 4″ schedule 40 PVC suction line was then installed in the slab, sealed and was extended to the left exterior of the home. The radon fan was then mounted on the left exterior of the home. The radon vent pipe was extended above the roofline to expel the radon gas safely. The manometer gauge (homeowner radon fan monitoring vacuum gauge) was installed on the suction line pipe in the basement for easy viewing. Then, we installed a Radon System Alarm. They are now required on all new residential radon systems. This unit is a vacuum monitoring device utilizing piezo resistive pressure sensor (PPS) technology. This alarm will provide an audible and visual indication to alert the homeowner when the radon system is not moving sufficient air in the event of a power loss to the system. Lastly, we preformed a post mitigation test that came back at 2.8 pCi/l!
It was a pleasure helping Stephanie make her home happy, healthy, & safe!
