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 Crawl Space Vapor Barrier

    Posted by Anthony L Bowers on May 5th 2021

    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.

    12-Mil Crawl Space Vapor Barrier

    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.

    A little dissapointed

    Posted by Winston on Mar 16th 2021

    I needed up ordering from Crawlspace Ninja because after doing tons of research o wanted to use a thicker 10-12m material. I had already previously ordered some sheeting that was clear but really wanted WHITE. The pictures show it being completely white. The description says it's white. But it is more of a translucent white/clear. You can see through it, but not easily and it more of a "frosted glass" effect than it is white. So they white tape stands out like a sore thumb. I paid more for the product for the "White" and it just wasn't. Otherwise very thick plastic. I went ahead and used it cause I had to get done.

    Best product ever

    I only wish I had done it sooner! My crawlspace is very short, and this product was surprisingly easy to work with while lying flat on my stomach. Humidity dropped within a day. VERY HAPPY!!

    A high quality product

    I looked locally for something which could compete with this product with no success. It makes me want to go into my crawl space and vacuum the floor!
