Put the 12 mil barrier under my 10 yr old house. Stopped the dirt smell and the humidity problem. Awesome product. Easy to install. Recommend getting the tape that's used to secure the barrier to the wall.

This is three times heavier than anything I can find locally. I precut into sheets in the yard, I think dealing with the roll under the house would be quite hard. It's a bit stiff to get into the crawl space and unfold. As with another reviewer, I'm glad that day is behind me. I was sooo sore! It cuts like plastic with sizzors. The rocks and bits of broken concrete left from construction only put dents in this product, no holes. I am impressed with its strength.

Perfect product for my crawlspace. I am 75 years old and installed it myself in one week-end. Received the order promptly in three days. Excellent service and good experience all around.

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.
