I covered my dirt crawl space, bought a Fantech fan, built a 4” exhaust system and a 3” intake system servicing the crawl space, lower concrete slab and the garden level concrete slab. We dropped our radon reading from over 9 to a little over 1. We used your plastic system along with your tape. We are pleased with the results.

Great product. Strong and very easy to work with. Did a great job repairing torn seams.

excellent product. My contractor, said that I had chosen good.

strong and very sticky! - much better than duct tape, and worth the price

I was able to purchase all material with a dehumidifier and condensation pump for 3700 lower than the best estimate I got without one. Took me a few days to do this. It is awesome.
