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?

Right amount of stickiness, matches barrier for solid, continuous look, seals extremely well, does not tear. Excellent product.
Sticks and holds seams together wonderfully!
Works great! No complaints
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.
Order a few more rolls to complete a Radon system in my crawlspace.
Great product. Holds and seals tight.
Sticks much better than a competitor that I started with on my vapor barrier.
This product nicely compliments the 12 mil vapor barrier. This roll goes a long way. I highly recommend.
