I used 1 roll of the 12 mil and larger roll of the 20mil. Both are fantastic. I had old clear 6 mil, which I went right over. Once I had the entire floor covered, even before taping the seams, I could feel and smell the difference in moisture reduction. I followed all of the videos and written process.

The 20 mil vapor barrier was great, easy to work with and my customer was well pleased. I will use again because it exceeded my expectations in every way.

First, Crawl Space Repair is a fantastic company to deal with. They keep you informed of your order every step of the way and provide free fast shipping (overnight in my case). Do not hesitate to order from crawlspacerepair.com.



I am extremely happy I went with this 20mil vapor barrier for my crawl space encapsulation. Very thick and durable. Note, It is a bit of a handful to handle by yourself. I chose the 13' folded, but if I was to do it again, I would've gone with the 6' non-folded to make the solo install easier. It is a bit tough to get into corners and around tight spaces, but very much worth the effort. No doubt this will hold up for the life of the house.

 

The liner was really strong and easy to work with because it was so durable. It is rigid enough to move all as one unit once you have it spread on the ground. The only issue was first getting started because the 1000 square foot roll weighs 100 pounds so its hard to manage at first.

Great product!! Would recommend.
