Stego® Crete Claw® Tape 6"

Mechanically Seal Membrane To Cast Concrete Slab

Stego Crete Claw Tape is a multi-layered tape that is used to seal Stego Wrap to the underside of the slab while the concrete is placed. Stego Crete Claw Tape allows wet concrete to cast into the textured top surface to form a mechanical bond/seal. This is useful in void/carton form applications and/or when soil movement may later occur.

Its many features include:

  • Dimensions: 6" x 180'
  • Comprised of a polyethylene film, aperture film, and an acrylic, pressure-sensitive adhesive
  • When applied to seams and along the perimeter, bonds the vapor barrier to the under-side of the slab and holds it there after soil or void/carton form movement.
  • Made in the USA with US and global materials
