HDPE geomembrane liners are the preferred product for lining projects. HDPE liners are resistant to many different solvents and are the most widely used geomembrane liner in the world. Although HDPE geomembrane is less flexible than LLDPE, it provides higher specific strength and can withstand higher temperatures. Its exceptional chemical and ultraviolet resistance properties make it an extremely cost-effective product. This high quality, high density polyethylene (HDPE) comes in the form of geomembranes with two co extruded, textured surface and consisting approximately 97.5% polyethylene, 2.5% carbone black and trace amounts of antioxidants and heat stabilizers; no other additives, filters or extenders are used.
In tanks, HDPE liners are used to form a protective internal barrier that ensures total sealing efficiency and protection from leakage, cracking and erosion. The use of Polyethylene Geomembrane (HDPE) greatly helps in preventing the corrosion and deterioration of water tanks, as the geomembranes are made of high quality, virgin polyethylene which demonstrates excellent chemical resistance i.e. to oily wastes, acids, and hydrocarbons. Under normal conditions aggressive organic solvents and inorganic acids do not cause any serious effects.
Protection aside, HDPE liners in water tanks also help to improve their lifespan. They're easy to install and weld, and are non-toxic materials that are certified safe by authorities worldwide.
They come in numerous versions including high temperature geomembranes - specially engineered HDPE geomembranes that are able to retain their mechanical and physical properties when exposed to temperatures up to 212F.
This versatile material can also be used to line anything from irrigation ponds, canals, ditches & water reservoirs to mining heap leach & slag tailing ponds, golf course & decorative ponds, landfill cells, covers, & caps, wastewater lagoons, and more.
