Paraseal® is a sheet waterproofing membrane consisting of 15 mils of HDPE and expandable, granular bentonite. The composite weight of the material is up to 1.0 lb/sq ft, creating a dual waterproofing system. 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.
Designed for use on backfilled walls.
Can be used on damp or green concrete.
Can be used in conjunction with TREMDrain® Series Drainage Mats.
Alternative versions of Paraseal are available for lagging, split slab, under slab and methane barrier conditions.
A protection course is not required, however, drainage is always encouraged.
