Basement & Radon Solutions installed a Sub-Membrane Exterior radon mitigation system for Bill. A 4″ radon depressurization suction line was installed in the crawl space. Then we installed our 9 mil vapor barrier that will cover the crawl space floor and be mechanically fastened to the foundation walls &/or sod pinned to the ground. The suction line then extended to the exterior of the home. The radon fan was installed on the right exterior of the home. The radon fan vent pipe from the fan extended to just above the roofline to expel the gas safely. Varmint and rain guard PVC exhaust caps are installed on all Basement & Radon Solutions exterior radon systems that prevent rain, debris, small animals and birds from entering the vent pipe, guarding and extending the life of your radon system. If desired the exterior system can be painted in the future for added aesthetics. This 4″ piping system will reduce radon levels in the home up to 33% opposed to using a 3″ suction line line. Then, we installed a Manometer – Vacuum gauge – installed on radon vent pipe for easy viewing. A homeowner monitoring gauge to insure radon fan is operational. Also a Radon System Alarms. which 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 0.6 pCi/l!
It was such a pleasure helping Bill make his home happy, healthy, & safe!
