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.

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 am completely out of my comfort zone at ordering these items..I was having someone with knowledge help me with my crawlspace repairs so we relied on the quality of product, the easy to read descriptions of the product and the fast delivery. I am so very pleased with all that I ordered and would recommend their products 100%.

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!

I purchased the 6 Mil Crawl Space Liner to create a vapor barrier on the dirt floor of my basement to help solve a moisture and mold problem I have. The product arrived promptly and was exactly as described. Installation was very straight-forward and the tape is the extremely sticky and durable. I'm currently putting pea stone on top of the liner and then I'm done. Dehumidifier is running in the basement and in only 2 days has dropped the humidity 20 points. I highly recommend this product.
