Love this tape. Easy to use and sticks to the liner very well. Does not allow for moisture penetration. Wish it tore a little easier for quicker use.

The Waterproof seam tape was very sticky and did a great job of joining the overlapping barrier material. My only problem is I ended up running out and had to order additional rolls. I underestimated how much I needed to seal the cuts around columns and some of the additional cuts I needed to close a partially excavated crawlspace. I probably used more than necessary but I wanted a good seal and only wanted to do this one time,

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.
