EPI's PVC fabricated geomembrane liners are single-ply construction. Polyvinyl Chloride is the main polymer. EPI uses only first quality virgin resins and each material meets or surpasses the ASTM D 7176 minimum specifications* for materials and ASTM D 7408 minimum specifications for seam strength.**
PVC Liners are fabricated by EPI in panel sizes up to 40,000 square feet, accordion-folded in both directions, and packaged for shipment to your site—our process helps you get your liner installed quickly and easily to save you time and money.
EPI uses statistical process control (SPC) to ensure the quality and integrity of each panel we produce. EPI is the only fabricator to remove samples from actual factory seams during the welding process for a rigorous, proven testing procedure that assures you of the highest quality factory-fabricated PVC geomembranes available.
