This heavy-duty vapor barrier seaming tape gives concrete crews a fast, reliable way to close seams, patches, and penetrations on sub-slab membranes. Built for professional use, it maintains a tight seal so the barrier performs as intended through placement and trades traffic.

• Seal overlaps, seams, and terminations on sub-slab vapor barriers for continuous protection under the slab.
• Bond aggressively to clean polyethylene, concrete, and penetrations to reduce blowouts and rework during placement.
• Detail pipe, conduit, and footing interfaces quickly to keep inspections moving and schedules on track.
• Withstand jobsite traffic, folding, and drag without lifting, supporting long runs and large-area installs.
• Patch membrane damage fast so crews can pour without delays or callbacks.

Compatible with Drago Wrap and most polyethylene vapor barriers; achieve best results on clean, dry surfaces with firm roll-down.
