SDS Sheet Paraseal® LG is a sheet waterproofing membrane consisting of 20 mils of HDPE, expandable, granular bentonite and a protective layer of spun polypropylene. The composite weight of the material is up to 1.0 lb/sq. ft., creating a dual waterproofing membrane.
The nature of Paraseal® waterproofing system allows for installation over damp or green 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.
Paraseal LG is designed for use over lagging on blindside walls, under slab, and buried forms such as elevator pits. It may be used on backfilled walls.
