This was my first time using and doing a project like this! make sure to measure and cut before you bring into the crawlspace fold it up and go into space and unfold TAN SIDE DOWN, when you cut the next piece I suggest you over lap pieces by at least 3" , I was so impressed with the quality,make sure you have sharp razors to cut because there is some poly type string that runs thru it for durability a good razor will be no problem, now I know the true test will be in the coming cold months and the years as they pass to see how it truly holds up but thus far Im very pleased with this material and its purpose. I dont often write reviews but I felt compelled to let homeowners and contractors know you will not be disappointed, unless of course you cut corners and do a cheap lazy job that will be on you and not the product. I will buy again at another location and I will highly suggest to friends and family to buy!

I bought two rolls of the 12mil anti microbial Liner. I did a 1500sq ft. crawl space and I had plenty for the job. I will use the leftover pieces to put under the tubs I will be using for storage. I will also use a piece to put down when I work under the house doing plumbing, electrical, and AC work. I am very impressed with the quality of the American made products! I have just ordered my Santa Fe dehumidifier and I am excited to see my humidity drop!

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

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.

Good quality for the money...
