Drago Wrap Soil Gas Barrier

Heavy‑duty under‑slab gas and vapor membrane for concrete contractors who need proven control of radon, methane, VOCs, and moisture. Suits medium to large pours, keeping schedules on track and floors protected from vapor intrusion over the long term. Block soil gases and water vapor beneath slabs to protect indoor air and flooring systems. Cover more area per roll to speed installation on large projects and reduce seam counts. Resist punctures and jobsite abuse to maintain barrier integrity during reinforcement and placement. Meet ASTM E1745 vapor retarder requirements to support code and spec compliance. Seal seams and penetrations reliably with system tapes and mastics for tested VI performance. Use with compatible tapes, mastics, boots, and term bars; install on prepared subgrade with sealed laps and detailed penetrations.
