The Enviro Liner® 6000 series is ideal for applications such as water and waste water, secondary containment, soil remediation, and pond and canal liners. The Enviro Liner® 6000 formulation includes a proprietary UV inhibitor/antioxidant additive package which makes Enviro Liner® 6000 the most durable thin film geomembrane available on the market for exposed service applications. The Enviro Liner® 6000 series has been tested extensively using accelerated weathering equipment, and the black styles have been shown to provide the same exposed service life at 30 mil as can be expected from 60 mil HDPE. In fact for the black styles of the Enviro Liner® 6000 series (at 30 and 40 mil) an extended 20 year exposed service weathering warranty is available.
