Used 10 mil plastic for barrier and tape held. Wasn’t quite as tight as I would have liked but still was great.

good quality product

We used this with the felt mat also available on this site. So far we have installed the barrier only on the floor and we plan to install rigid insulation on the walls next weekend. The musty smell in the basement is greatly reduced already and the whole house smells better even though we haven't finished the entire project yet.

I am very happy with this liner. Combined with the foundation seal tape and the seam tape I was able to encapsulate my crawl space for 1/10th the price I was quoted by a local company. I had to level some dirt myself, but once that was done, this liner was great to work with. I wish you could smell my crawlspace now- it smells like nothing! beautiful, fresh, nothing!

Super fast shipping order was correct every time i order
