With rock hard chunks of clay and sharp pieces of concrete debris all around, anything less then 20mil would have been a disaster. If I had to do this job again, I would have gotten 2 six foot wide rolls rather then the 13 foot wide roll. The 13 foot width was very difficult for my brother and me to manage when your on your knees and belly.

Bought this to encapsulate my crawl space. Great product very pleased with it.

This stuff was easy to use and virtually indestructible. High quality product. Would highly recommend it.

Our contractor has completed installation of the vapor barrier in our crawl space.....he was very satisfied with the components we purchased from you. Your membrane was clearly superior to materials available locally.

I went with a 20mil silver back vapor barrier on the ground in my crawl space .Its durable easy to work with . I'm so pleased with my purchase . Thanks crawl space repair.
