Impermeable Liners

A common thermoplastic resin, PVC (polyvinyl chloride) is used in wide array of manufactured products and is the most commonly specified lining material in the industry. It is a highly flexible, non-reinforced, cost-effective, waterproofing geomembrane with many uses and advantages for the user. PVC has excellent abrasion resistance and high puncture strength. It is resistant to a number of industrial chemicals, making it ideal for ponds, landfill caps, and wastewater facilities. Due to its high flexibility, PVC liners readily conform to sub grade contours and offer excellent interface friction without being textured. The use of a PVC liner prevents contaminants from entering groundwater sources or streams. In addition, it conserves potable water resources by preventing seepage loss.

A petroleum based material, HDPE (high-density polyethylene) geomembrane is commonly utilized for solid waste and water containment applications due to its exceptional resistance to sunlight exposure and wide variety of chemicals. Among the other types of geomembranes, HDPE liners offer the lowest permeability for minimal seepage loss. It also resists cracking and thermal stress making it a reliable choice for various lining requirements whether it be for landfills, canals, decorative ponds, or animal waste containment.
