About This Product

Details

Paraseal GM is a sheet waterproofing and methane-mitigating membrane. It consists of 20 mils of HDPE and expandability granular bentonite. 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.

  • The Paraseal GM/LG – 20 mil system combines the dual waterproofing system, Para JT Tape seam tape and Parastick ‘n’ Dry Tape to create a robust yet flexible, waterproof and methane-mitigating membrane
  • The nature of the Paraseal waterproofing system also allows for installation over green or damp surfaces accelerating the construction process
  • The bentonite can expand up to 8 times its original thickness to stop water that may make it past the HDPE layer, providing a second layer of protection

Applications

Paraseal GM/LG – 20 mil is designed for use in post-installation submerged conditions, on blindside walls, shotcrete walls and under slab where hydrostatic water head and/or methane conditions exist. It may also be used on backfilled walls.
