PVC Fabricated Geomembrane Liner Meets ASTM D7176 Specifications
EPI’s PVC fabricated liners are of single-ply construction, featuring Polyvinyl Chloride as the predominant polymer. Only first-quality virgin resins are used and every material used either meets or exceeds ASTM D7176 minimum specifications* for materials and ASTM D7408 minimum specifications for seam strength.**
​
The fabricated PVC geomembrane liners made by EPI are crafted in panel sizes of up to 40,000 square feet, conveniently accordion-folded in both directions. These PVC liner panels are then carefully packaged for shipment to your project site for simple installation that will save you both time and money.
​
EPI’s unique testing process (referred to as the Wolschon Test) involves removing samples from actual factory seams during the welding process for a meticulous, proven testing procedure that will make certain that each factory-fabricated PVC geomembrane liner we create is of the highest possible caliber.
​
The statistical process control (SPC) that we follow at EPI ensures the uncompromising quality and integrity of each PVC geotextile liner we create.
