Product Details

This vapor barrier seam tape gives slab crews a practical way to seal overlaps, repairs, and detail areas during under-slab moisture protection work. It helps maintain continuity across Stego Wrap installations, reducing rework risk before reinforcement and concrete placement.

  • Seal vapor barrier seams to support a continuous below-slab moisture protection layer.
  • Patch tears, punctures, and jobsite damage before the slab pour.
  • Bond detailing areas around penetrations, edges, and overlaps with clean manual application.
  • Keep installation crews moving with a tape format suited to medium and large slab jobs.

Use this tape for vapor barrier detailing only; it does not replace structural adhesives or mechanical fastening.
