Basement & Radon Solutions installed a Sub-Membrane Exterior radon system for Steve. A 4″ radon depressurization suction line was installed in the crawl space. We installed a 9-mil white 100% woven reinforced ground liner over all the earth in the crawl space. The ground liner was mechanically fastened to foundation walls and piers, all lap joints were sealed with tape manufactured specifically for our liner to prevent moisture and soil gas penetration. Our woven liners are guaranteed to not “off gas” (cat urine odor).The suction line was extended to the left exterior of the home where the radon fan was installed. The radon fan vent pipe from the fan extended to just above the roofline to 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. 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 mitigation test for Steve that came back at 0.9 pCi/l!
It was a pleasure helping Steve make his home happy, healthy, & safe!
