Stego Wrap Vapor Barrier/Retarder

Stego Wrap Vapor Barrier/Retarder

Stego Wrap Vapor Barrier/Retarder is a high-performance below-slab vapor protection system designed to resist moisture intrusion and soil gas migration in residential, commercial, and industrial concrete applications. Made from a proprietary blend of prime virgin polyolefin resins and additives, it provides long-term durability and protection beneath concrete slabs-on-grade.

This vapor barrier helps prevent costly flooring failures and reduces the migration of harmful soil gases such as radon and methane. The 10-MIL version is a cost-effective vapor retarder that exceeds ASTM E1745 Class A requirements—ideal for projects with moderate protection needs. The 15-MIL version offers enhanced puncture resistance, extremely low permeability, and comes with a Life of the Building Warranty, making it the flagship product for critical slab protection.

Both versions are manufactured in the USA and exceed ASTM E1745 Class A, B, and C standards. They resist deterioration, are simple to install, and are backed by years of proven field performance. Whether you're working on a standard build or a high-spec project, Stego Wrap delivers a reliable solution for under-slab vapor and gas control.
