Paraseal GMLG Multiple Component Membrane

Check up to five results to perform an action.

Paraseal GM LG is a multi-layer sheet membrane waterproofing system installed with Para JT Tape to form a superior membrane barrier to both water and aliphatic gases. It consists of a self-sealing, expandable layer of granular bentonite laminated at the rate of up to one pound per square foot to an impermeable, high density polyethylene (HDPE). The third component is a protective layer of spun polypropylene. Together, these three components with Para JT Tape form a tough, high performance waterproofing membrane manufactured in controlled thicknesses of 170 mils to 200 mils, specially designed for blindside installations such as lagging, under floor and elevator pits. Paraseal W/GM/LG also withstands applications where shotcrete is blown directly into the face of the membrane. This is not a containment membrane.

Basic Uses
Paraseal W/GM/LG is especially 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 W/GM/LG will also exhibit outstanding protection against water intrusion in areas of high water heads. Paraseal W/GM/LG is also used with Para JT Tape to waterproof and/or gasproof structures below grade with integrally bonded seams. The Para JT Tape is installed within the Paraseal W/GM/ LG membrane sheet overlaps where it remains protected while providing a flexible, waterproof and gasproof seal.
If groundwater is brackish, consult Tremco. Do not apply in standing water or over snow. Paraseal products require compaction/ confinement to be effective. A minimum 24 psf confinement is required. Contact your local representative or Technical Services for more information.
