Description:

GTM-20 is a high performance waterproofing protection sheet and slab vapor retarder developed for GEL-TECH SYSTEMS. It is also used to control radon, methane, sulphates and other soil contaminants. GTM-20 Protection Sheet is a high density, cross-laminated polyethylene with a geotextile fabric reinforcement layer that resists punctures and tears. The sheet is UV stabilized to withstand prolonged exposure to sunlight and also meets ASTM standard D3083 Soil Burial test performance requirements. GTM-20 mil reinforced protection sheet is not prone to environmental stress cracking (ESC) so it can endure repeated thermal expansion and contraction cycles.

GTM-20 Protection Sheet is used in GEL-TECH SYSTEMS GTS-350 positive side and GTS-500 blind side waterproofing systems for above and below grade construction. GTM-20 is ideal for use in harsh environments along with GTS Poly-Rubber Gel to create an effective, permanent waterproofing system.

GTM-20 Protection Sheet is applied in both above grade and below grade applications. GTM-20 is suitable for new construction and repair. Applications include the following types of waterproofing: horizontal positive side waterproofing (GTS-350); vertical wall positive side waterproofing (GTS-350); and blind side waterproofing (GTS-500). Areas of application include: plaza decks; elevator pits; poured wall foundations; block wall foundations; brick wall foundations; granite/limestone foundations; split slab construction; diaphragm wall (blind side); and green roofs.
