The vapor barrier was Very strong and the shipping was very fast. Would highly recommend.

I used this material on the piers and walls. It wasn't easy to cut, which I was happy with because it showed the strength of the material. I had no issues with installing.

Not a professional and I was able install the Diamond Back barrier in my 1600 foot crawl space, mostly by myself, after watching a few videos provided by Crawl Space Repair. I'm not saying it was easy, it took me about 2 weeks and it's not as pretty or perfect as I'd like, but being a 59 year old woman with a few physical limitations I'd say that is a testament to ease of installment. The quality seems very good, but the judge of that will come after a few years. So far I'm happy with the result and I can now store a bunch of stuff under the house.

I decided to give a new company a try crawlspace repair was the best hands down. My material was delivered within 3 days of ordering! The material so far has held up great the only down side was my roll of liner was 13' by 100' which was great bigger the better in my eyes. But it was folded in half which made it to hard to roll out and un fold in the crawl i did it all out side. Other then that its been the best products I've used so far. I do a lot of crawl space work and plan to use this liner every time

I am very pleased with the product, purchase and service. You are a great place to do business.
