We Value Quality Over Quantity
EPI's Quality Control Manual has been carefully designed to surpass both industry requirements and customer expectations. Our PVC Liners are fabricated in panel sizes up to 40,000 square feet, conveniently accordion-folded in both directions, and packaged for shipment to your project site for efficient and convenient installation that saves you time and money. EPI utilizes statistical process control (SPC) to ensure the quality and exceptional integrity of every panel we provide. We are the ONLY Fabricator in North America that doesn't just test on "representative" samples — we remove actual test samples from factory seams during the welding process to rigorously and accurately test our high-quality product. This effective testing has proven time and time again that we create the highest quality factory-fabricated PVC geomembranes available in the industry.
