Stego Wrap 20 Mil Vapor Barrier | 14' x 105'

Engineered for commercial slab installations and residential basement floors where moisture migration control is critical. This 20-mil vapor barrier from Stego Industries delivers heavy-duty protection against ground moisture and soil gases that can compromise concrete integrity and flooring systems. The 14' x 105' roll provides 1,470 square feet of coverage, reducing the number of seams on larger pours. Manufactured to meet ASTM E1745 Class A specifications for under-slab vapor retarders, this material installs between the subgrade and concrete to prevent water vapor transmission that leads to adhesive failure, mold growth, and coating delamination. The 20-mil thickness resists punctures during placement and concrete placement operations. Built for commercial contractors, residential builders, and specialty flooring installers working on projects that require verified moisture protection under concrete slabs.
