Poly Vinyl Chloride (PVC) is the most commonly specified lining material in the industry. Manufactured by the calendaring or extrusion process, it is a highly flexible, non-reinforced, cost-effective, waterproofing geomembrane with many uses and advantages for the user. PVC has high puncture strength and excellent abrasion resistance. It is resistant to a number of industrial chemicals. Because of 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.
PVC is available in a variety of formulations including fish grade and oil resistant. It is available in 20 mil, 30 mil, 40 mil and 60 mil.
