Extremely tough, well made material. My son and I installed this in our crawl space after watching the helpful videos on this website. Shipping was very quick and the product seems very well made. For a permanent moisture barrier, this is worlds above anything I could find in local stores, and after seeing how well it is made, it's actually a very fair price for the quality of the product.

Made in USA

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.

Need better shipping cover
