Basement & Radon Solutions installed a Sub-Slab/Sub-Membrane mitigation system in for David. The radon suction line proposed was installed in 1st crawl space to the existing radon pipe and connected to a suction point outside the crawl space door into the concrete slab. The 2nd crawl space was installed to the radon suction pipe and connected to a suction in the concrete slab inside the crawl space. After diagnostics for system performance, a 5″ diameter hole was drilled through the concrete slab to the earth below. This is where the suction pit was then created. A 4″ schedule 40 PVC suction line was installed in the slab and sealed. The suction line was then extend to the crawl space. A radon suction line was installed on the ground in the crawl space, our radon barrier covers the suction line and the earth in the crawl space. The suction line was connected to the basement suction line and was extended to the right front exterior of the home, for the 2nd crawl space and the 1st crawl space was extended to the rear left corner of the home. The radon fan was mounted on the exterior of the home with the vent pipe extending above the roofline to expel the radon gas safely. A manometer gauge (homeowner radon fan monitoring vacuum gauge)was installed on the suction line pipe in the basement for easy viewing. 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.
After that we preformed a post mitigation test for David that came back at 0.7 pCi/l!
It was a pleasure helping David make his home happy, healthy, & safe!
