Paul got his radon gas levels checked in his home and it was elevated and would fluctuate from 5.5pCi/L to 9pCi/L. His home is also on a 1/2 basement & 1/2 crawl space.
Solutions provided:
Basement & Radon Solutions installed a Sub-Slab & Sub-Membrane radon mitigation systems for Paul. The radon suction line was installed in the basement slab from the crawl space. After diagnostics for systems performance, a 5 diameter hole was drilled through the foundation wall below the concrete slab to the earth. This is where a suction pit was then created. A 4″ schedule 40 PVC suction line was installed in the slab and sealed. Then the suction line was extend to the crawl space. A radon suction line was installed on the ground in the crawl space. Our radon barrier- 9-mil white 100% woven reinforced ground liner- was installed over all of the earth in the crawl space. The ground liner was mechanically fastened to the foundation walls and piers. Then, all of the lap joints were sealed with tape manufactured specifically for our liner to prevent moisture and retard soil gas penetration. Then the suction line was connected to the basement suction line and was extend to the right exterior of the home. The radon fan was mounted on the exterior of the home with the vent pipe extending to above the roof line to expel the radon gas safely. A Manometer gauge (homeowner radon fan monitoring vacuum gauge) was also installed on the suction line pipe in the crawl space. A varmint and rain guard PVC exhaust caps were installed on the exterior radon systems. These caps prevent rain, debris, small animals, and birds from entering the vent pipe. Which is guarding and extending the life of Paul’s radon system. If desired the exterior system can be painted in the future for added aesthetics. By adding those radon mitigation systems we got Paul’s radon down to 0.8pCi/L! It was a pleasure helping Paul make his home safe, happy, and healthy!  “
