Basement & Radon Solutions added a radon fan to the Passive system to make it Active. We installed an HP220 radon fan R3. This fan comes with a 5 year manufacturers warranty. We extended the radon pipe that is connected to the radon fan, up and above the roof line to expel the radon gas safely. We also added out 9 mil white 100% woven reinforced ground liner over all earth in the crawl space. The ground liner was mechanically fastened to foundation walls and piers. All lap joints were then sealed with tape manufactured specifically for our liner to prevent moisture and retard soil gas penetration. By making Gale’s Passive system Active we were able to bring down the radon levels to 0.4 pCi/L! It was a pleasure making Gale’s new home healthy, safe, & happy!
