Basement & Radon Solutions installed a Sub-Slab Exterior mitigation system for Stephan. The radon suction line proposed was installed in the right end basement 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 then extended to the right exterior of the home. The radon fan was mounted on the right exterior of the home. Then, the radon vent pipe was extended above the roofline to expel the radon gas safely. Then, a manometer gauge (homeowner radon fan monitoring vacuum gauge) was installed on the suction line pipe in the basement. We also installed a Radon System Alarm. Radon System Alarms 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 test for Stephan that came back at 1.3 pCi/l!
It was a pleasure helping Stephan make his home happy, healthy, & safe again!
