Crawl Space Liner- 8 Mil DiamondBack

This crawl space liner is American Made. It is a string reinforced polyethylene vapor barrier that is white on one side and black on the other. This product has no warranty. 

Facts about this product

  • Roll size 13'4" x 75'
  • It is a nominal 8 Mil product which means it is not actual thickness at the plastic, its measured at the string just like ALL the other 8 Mil liners on the market today
  • Made in the USA
  • Bright white face and a black back
  • Shipping is included in the price when you purchase $200 or more! Some restrictions apply see checkout page for details
Due to the expanding and rising UPS handling and shipping fees we are forced to add $9.28 at checkout for each roll.

Rating Top Quality & Quick Shipping
The shipping was very quick and the material was packaged very good. I haven't finished yet, but the material is top quality and very easy to work with. I saved thousands of dollars by doing it myself. I would recommend CrawlSpace Repair to any one.

I was given a quote of $4500. to install a vapor barrier in a 35ft.x45ft. crawlspace, so I decided to try to do it myself. I found crawlspace repair .com on the internet. I decided to use the 12mil. vapor barrier instead of the 6mil. that the quote was for. It was not hard to install, if fact it only took a few days by myself. The end result looks very professional and total cost was less than $1000. This is an excellent product and I would recommend it to all.

I should not have waited so long. Used 6mill on side walls and 20 mill on floor. Very bright and a pleasure to go under house now. Easy to install and Larry at Crawl space repair was very helpful. Great product and $5000 dollars less than a local company wanted for lesser product.

Rating Vapor barrier.
I wasn't sure about buying because of the expense, but it's an excellent product. It's much stronger than a simple sheet of plastic. It arrived quickly, it's easy to cut and handle. Being white, it also brightens up the space, so I can better see what I've stored there. I'm very happy with it. The end result looks very professional.

Rating Love the outcome
I have to say, I was a little anxious to tackle this type of job for the first time. Once the products arrived, I had to sit and visualize the proper way to unroll the wrap, to ensure I wouldn't have to try swapping ends and such with it unrolled. Once I had my plan, the instal went pretty well. Luckily, my crawlspace has enough room for me to just have to squat or sit at the smallest section, so getting around to do the work was not so bad. The tape allowed me to do it myself, and control the layout. All in all, I am very pleased with the quality of the wrap, the tape, and the seam tape. The end result is almost like having a new house! It looks clean, bright, and invites gawks and stares from family and friends. Thanks for the helpful vids too. One suggestion would be to have a video that has hints on: best way to start; which way it will unroll; doing the corners; etc... for newbies like me!
