Plastatech Tech 5® Geomembrane

Plastatech Tech 5 geomembrane helps contain harsh chemicals and other pollutants commonly found in landfills, reservoirs, chemical processing plants, refineries, manufacturing facilities and water treatment operations. It is reinforced with a high-tenacity, non-wicking, polyester scrim that provides exceptional dimensional stability, puncture strength and long-term durability. Our proprietary process delivers a cohesive bond between the high-thread-count scrim and the films, creating a non-separable, long-lasting adhesion that will not delaminate.

Tech 5 is available in 30-mil thickness.
