Usually this is a great product for draping the crawlspace walls. I've used it multiple times and the only problem I've had was on a recent order. One roll had a really messed up end, as if the machine needed calibration. It was difficult to use but we got the job done. And one roll out of the many I've ordered over the years is no big deal. I still highly recommend this product.

I used this vapor barrier to fix an existing area under my home that was not done correctly when the house was built. I am extremely pleased with the strength and durability of this vapor barrier. I would definitely use this product again. It is well worth the price and regular poly sheeting doesn't even come close to delivering the same performance.

Excellent product, easy to work with including the Waterproof Seam Tape™ for Crawl Space Vapor Barrier.

Customer service beyond compare.

Product shipped on time and arrived in great condition. Superior packaging.

Knowledgeable, friendly phone assistance for all my questions.

I will use this company for all my future needs and highly recommend it's products both for quality and price.

Product is great, I have gravel for my soil so I was forced to use their under barrier protection otherwise the product would of kept getting holes punched through it. But the reinforcing helped a lot. The 6 mil thickness made it easy to work with in tight spaces.

What a great company you have. Professional, polite, and on-time delivery. I had a 3300 sq.ft. of crawl space to encapsulate. I did it with the 6 Mil DiamondBack, taped the piers, and installed as instructed. Simply amazing. It was a lot of work, so I did it in phases. I recommend everyone use this material. We had a very good experience with your company. You sell top shelf supplies and at very reasonable prices. Thanks!
