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?

    12 mil vapor barrier

    Just getting started but we are happy with how easy the 12 mil vapor barrier is to work with. We've put a few holes in it but we take responsibility as part of our learning curve against the raw concrete edges at the joints. Thankful for the ninja videos! Now we need to refind the one that shows how to do corners!

    12 Mil Crawl Space Vapor Barrier

    Does the job and does it well. It thick enough and is white so it 'brightens' up my crawlspace. Does not tear, which is very important. Tape adheres well to it and stays adhered. The aspect that keeps it from getting 5 stars is that the end of the roll has a lot of ripples in it. To the extent that sometimes the last 5 feet are unusable. The ripples make is near impossible to cut straight, but also prevent the product from laying flat and straight. And, it's impossible to get a good seal when taping the ripples. So, as mentioned, a rippled section is discarded.

    Great product! Unrolled nicely and then unfolded nicely.

    Had I purchased enough the first time around, I would have been able to encapsulate the entire crawl space in 7 hours. I would recommend!

    I was a little worried about thickness of 12 mil liner but after watching videos of reinforced liners getting cat smell i decided to go with your liner, very happy I did very nice product and thicker then I thought.

    Wow, do I love this product. I installed it in a really, really damp crawl space and within 24 hours the humidity dropped from 90+ to below 70, and that’s before I was able to tape the seems and cover the walls. The fabric is incredibly strong, a beautiful brilliant white, and easy to cut and install. I highly recommend this product.
