The Paraseal LG is a multi-layer sheet membrane waterproofing system with a protective polypropylene third layer to keep the membrane intact during the concrete pour or shotcrete application. The tough, durable HDPE layer provides high puncture resistance, eliminating the extra protection course for most applications. The bentonite can expand up to 8 times its original thickness to stop water that may make it past the HDPE layer to provide a second layer of protection. Its special weather treatmeant allows Paraseal LG to be installed for relatively long periods of time before the walls are poured.
Designed for use over lagging on blindside walls, under slab, to cover earth design cuts which are to serve as the external side of a vertical wall form and buried forms such as elevator pits. It may be used on backfilled walls.
Effective when waterproofing from the blindside (lagging etc) where the waterproofing membrane is applied before the walls or floor are poured.
It is designed to resist damage from multiple exposure to inclement weather, extremely abrasive concrete pours or direct installation of shotcrete.
Paraseal LG will also exhibit outstanding protection against water intrusion in areas of high water heads.
