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.

This is the best tape to utilize with the 12 mill vapor barrier.

Great Tape
This tape is great tape. I have not only used it to hold the vapor barrier but it is being used for many other projects that I needed a super bonding tape. It’s almost strong enough to pull the hair off your arms.

Tape Works
This is my first experience with crawl space tape. But, I can say this tape works well. I laid approx 100’ of it today between the strips of 12 mil in my crawl. This tape is slightly tough to cut with a sharp razor knife. If you stab it in the middle, you can cut half way through and then cut the other half. It appears to stick well to 12 mil but I wonder if it will pull up. I was able to pull it and reset it a few times. I did not waste any in the process. If you’re patient, you can lay straight wrinkle free lines. 4” is nice, it allows 2” on each side of a seam. You could not pull and tear this if you wanted, its that tough.
