WR Meadows Perminator 15 Mil Vapor Barrier 14' x 140' Roll (1940 sq ft)

Overview

PERMINATOR 15 MIL is a tough, flexible underslab vapor barrier designed to help block moisture, water vapor, and radon gas from entering concrete slabs. Made with advanced polyolefin resin technology, it delivers exceptional puncture resistance and one of the lowest permeance ratings in the industry—making it a smart choice for protecting floor coverings and reducing the risk of mold, mildew, and excess humidity beneath slabs. This durable 15-mil membrane installs quickly without the need for sand or gravel layers, and resists damage from jobsite conditions like foot traffic or equipment. It meets ASTM E1745 Class A/B/C and is suitable for slab-on-grade, crawlspace, and vertical wall protection applications. Made in the USA, PERMINATOR offers long-term vapor control to help keep interior environments dry and compliant with flooring manufacturer requirements.
