This is great quality 12mil vapor barrier, it is durable and works perfectly.if i had the money i would buy the 20 mil you could probably have a track meet on that stuff because the 12 mil was great!

We had an extremely wet spring this year and I had a strong musty odor coming up from the air returns into my home. The inside humidity rose to 81%. I contacted a contractor who happened to do work in a house with an encapsulated crawl space and thought it would be a good solution for me. Since encapsulating my crawl space and installing a dehumidifier and one fan, the humidity in my crawl space has dropped to a perfect 45% and the temperature is staying about 70 degrees. After just about one month, this seems to be a very good solution. The humidity inside my home is back to normal and the musty odor is completely gone.

Very good product, only thing it should be shipped in cardboard had a couple holes in lost 3 feet, from ship other than that good stuff

I sealed my partial crawl space with this 12 mil liner along with the felt underlayment, foundation seal tape and seam tape. Delivery was prompt and the products easy to work with. No pvc smell at all. I should have done this years ago! I had extra so I added a second layer where I store tote bins. The seal is so tight that the liner puffed up due to air infiltration.

HORRIBLE JOB!! But, that's certainly not the fault of Crawl Space Repair. Their products are very well suited for their intended use. I used 6 mil on the walls and 12 on the floor. i worked about 2-3 hours a day, 4 days a week on this project, and IT IS FINALLY DONE. The difference in humidity is unmistakable. You won't realize how damp your crawlspace is until you've sealed it. I still have some work to do, but the plastic is all down and the atmosphere under my house is greatly improved. Good products, FAST shipping.
