GPS HDPE Root Barriers are smooth, high quality, high density polyethylene (HDPE) geomembranes produced from specially formulated virgin polyethylene resin. This polyethylene resin is designed specifically for flexible geomembrane applications. It contains approximately 97.4% polyethylene, 2.5% carbon black and trace amounts of antioxidants and heat stabilizers; no other additives, fillers or extenders are used. GPS HDPE Root Barriers have outstanding chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability and thermal aging characteristics. GPS HDPE Root Barriers have excellent resistance to UV radiation and are suitable for exposed conditions. These product specifications meet or exceed GRI GM 13.
Popular uses include:
- Pond liners (safe for fish and plants)
- Root Barriers
- Canal Liners
- Tank Liners
- Many Landscaping applications including root barrier, under cart paths, edging golf courses.
- Excellent chemical resistance
- Outstanding stress crack resistance
- Lowest permeability
- History of proven performance Meet or exceed all aspects of GRI GM 13
