Basement & Radon Solutions installed a Sub-Membrane Exterior mitigation system for Cori. A 4″ radon depressurization suction line was installed in the crawl space, then our radon vapor barrier covers the crawl space floor and was mechanically fastened to the foundation walls. The suction line was then extended to the right exterior of the home. The radon fan was installed on the exterior of the home. The radon fan vent pipe from the fan was then extended to just above the roofline to help expel the radon 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 Radon System Alarm. Radon System Alarms are now required on all newly installed 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 2.6 pCi/l!
It was a pleasure helping Cori make her home happy, healthy, & safe again!
