    • Spec Sheet

    Our crawl space vapor barrier material is great for crawl space encapsulation, basement waterproofing and many other projects around the home. With all the hype about reinforced vapor barriers, homeowners should know that reinforced crawl space vapor barrier material may cause odor issues once installed.

    Using Reinforced Vapor Barrier in Crawl Spaces

    • Just about every waterproofing company is pushing reinforced crawl space vapor barrier material.
    • Reinforced vapor barrier material can separate over time because the cord is installed by gluing two pieces of plastic together.
    • The lack of separation in vapor barrier is only as good as the glue used.
    • When the reinforcement cord is exposed and becomes wet it can give off an odor similar to cat urine.
    • Why risk a potential odor problem by using a reinforced crawl space vapor barrier material?

      Vapor Barrier

      Posted by Rich on Apr 25th 2025

      This plastic is very strong. I was a bit worried since there was some concrete slag under a spot that I crawled over on the vapor barrier. I thought it might poke through, but it held up! I would recommend this product!

      12 mil vapor barrier

      Posted by Rick on Apr 16th 2025

      This 12 mil vapor barrier is highly quality plastic to seal your crawl space. I opened the boxes when I first got it to verify what I was getting and believe me it’s pretty tough plastic for crawl space. Remember to rake or clean area before installing to keep it from getting punctured

      Ninja 12 MIL Vapor Barrier

      Posted by Scott on Apr 3rd 2025

      I was surprised at the number of punctures in the material. Repairable with tape, but added time to the job.

      Great Vapor Barrier

      Posted by Brian Sommer on Dec 17th 2024

      Really like this Vapor barrier. Comes folded up and on a roll. Was easy to cut outside the crawlspace in the yard to length, re-roll, and then take it into the crawlspace. In the crawlspace getting it to fold out all the way flat was a bit of a chore but not too bad. I felt good knowing I was getting a thick, durable vapor barrier that would not degrade into the cat pee odor.

      Great Product

      Posted by Dan Kothlow on Nov 29th 2024

      This vapor barrier is thick, yet easy to cut with sharp scissors or a utility knife. It unfolds in a logical manner, making it easy to move into position and unfold, even when installing it by yourself. Combined with the butyl tape, it is very easy to attach to the foundation walls. Excellent product, and a good price.
