PARASEAL GM LG -20 MIL - 4' X 24' ROLL (96SF / RL)

Paraseal® GM is a composite-sheet waterproofing membrane that combines a thick layer of high-density polyethylene (HDPE) with expandable quality granular bentonite. Paraseal GM is manufactured to controlled thicknesses of 150-200 mils (3.75-5.0mm) and is installed as a system with Para JT Tape to form a superior dual membrane barrier to both water and aliphatic gases. It is not a containment membrane.

• Paraseal GM is used with Para JT Tape to waterproof and/or gas-proof structures below grade.
• Is installed within the Paraseal GM membrane sheet overlaps where it remains protected while providing a flexible, gas-proof and waterproof seal.
• Is excellent for use on poured concrete or block masonry foundation walls and it may be installed prior to the concrete pour such as on lagging, under floor slabs, in elevator pits, etc.
• Can be used in conjunction with TREMDrain® Series Drainage Mats.
