DragoSeal Tape

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.
