Plastatech® Tech 7®

Reinforced Geomembrane

Plastatech Tech 7 geomembrane is our toughest membrane yet, designed to remain strong in even the harshest environments and helping to contain a variety of chemicals and pollutants commonly found in water treatment operations. Reinforced with a high-tenacity, anti-wicking, polyester scrim that provides exceptional dimensional stability, puncture strength and durability, this geomembrane delivers a cohesive bond between the high-thread-count scrim and film, creating a non-separable, long-lasting adhesion.

Tech 7 is available in black 40 mil thickness.
