Crawl Space Seam Tape
A polyethylene film, single coated with a synthetic rubber pressure sensitive adhesive. This is not your average crawl space vapor barrier seam tape. This 4” 9-mil thick seam tape comes in 180’ (60 yd) long rolls. The color is bright white and is sure to help brighten your crawl space jobs. Our crawl space seam tape is polyethylene backed and single sided. It is great for any crawl space encapsulation or basement waterproofing project.
Waterproof Seam Tape for Crawl Spaces
Crawl Space Ninja Seam Tape is polyethylene film tape manufactured with a superior adhesive compound and intended for use in many applications; such as crawl space encapsulation, basement waterproofing, splicing, color coding, marking and sealing. This tape also offers noticeably better water and weather resistance than traditional crawl space seam tapes. This poly tape is commonly used in the marine, service, and construction industries among others. Poly tapes are frequently used in shrink film and zipper door applications.
Q: How Much Crawl Space Seam Tape Do I Need?
Typically, we recommend 1 roll (4"x180') for every 250 square feet of crawl space. Additionally, if you have support pillars, add 1 additional roll for every four pillars.

Great stuff. Hard to unroll. Maybe that's why it works so well.

I expected it to work better...I think if you were to use this tape on a new/barely seasoned crawl space, it would work better. My house was built in the late 90's and the crawl space wasn't much taken care of. Took it upon myself to do a DIY fixer up with new vents and new barrier. I purchased a brush to clean the walls but even after laboring against the walls, the tape wouldn't stick in majority places. I noticed it stayed on areas that were extremely clean and hadn't been exposed to much of the elements. But that was very few for me. I used it mostly to attach the barrier to other barrier. That worked just fine. I only wound up using half of what I bought, wasting about $100 and it was outside of the period to return. Plus it doesn't seem to make sense based on the costs to return. All that to say, consider what type of crawl space you have and how its' been taken care of before you go taping the barrier to the wall.

High Quality Seam Tape
This seam tape was very easy to work with in the crawlspace and seems very strong. I expect it to provide a good seal for the life of the vapor barrier. I will order this product again if needed.
