Paraseal® GM/LG is a sheet waterproofing and methane-mitigating membrane consisting of 20 mils of HDPE, expandable, granular bentonite and a protective layer of spun-bonded polyester. The composite weight of the material is up to 1.0 lb/ft², creating a dual waterproofing system. The HDPE extends beyond the bentonite on the perimeter edges to create a clean surface for Para JT™ Tape and Parastick ‘n’ Dry® Tape installation. – 20mils – 4′ x 24′
Paraseal GM/LG is designed for use in post-installation submerged conditions, on blindside walls, and under slab where hydrostatic water head and/or methane conditions exist. It may also be used on backfilled walls.
