PVC (POLYVINYL CHLORIDE) Geomembrane Liners

A proven history of performance since the 1950's when PVC was first introduced to the synthetic liner industry, PVC has become the standard material for many kinds of waste containment projects by both industries and municipalities. Government agencies like the U.S. Department of Interior routinely use PVC liners for the containment of precious water resources and for the protection of the environment throughout the United States.

Request a QuoteSeam Integrity gives you the reliability you need in every factory-manufactured panel of PVC. Factory seams are produced in controlled environments for maximum bonding, utilizing methods such as thermal and dielectric sealing. All factory seams meet the required values established by the National Sanitation Foundation(NSF). Quality control tests are continually run on these seams, including destructive seam testing. This all adds up to a PVC seam that gives you the strength and reliability you need.

Customized Panels mean lower installed costs. ETP PVC panel can be made in the factory in sizes ranging up to 30,000 square feet. Customized panels are particularly helpful in irregularly shaped installations, cutting material waste and reducing the number of field seams.

Field Seam Reliability is another way you can count on ETP's PVC because you can easily test all field seams on site to ensure their integrity. Using formulated solvents, crews can install up to 200,000 square feet a day without elaborate tools or equipment. All of the field seams can then be checked with a simple air lance test.

Puncture and Impact Resistance starts in the PVC's molecular structure. PVC has an amorphous molecular structure which allows PVC liners to conform to ground settling and irregular subgrades without yielding. Because it is not a crystalline structure like the other harder plastics, PVC has a low modulus of elasticity and no yield point. That means substantial dividends in three ways. First, environmental stress cracking is completely avoided when using PVC. Second, the build up of stress on the liner membrane and its seams can eventually cause a yield failure even at low elongations. Since PVC does not have a yield point, failure will not occur in this situation. Third, and regardless of thickness, PVC demonstrates 3-dimensional elongation properties(tri-axial deformation) making it more resistant to puncture and impact damage during both installation and during the design life of the liner system. Conclusive tests have proven what environmental engineers, installers, and project managers have known for years. PVC gives them the standard of reliability over time.
