Applications

A heavy duty yet lightweight sheeting material perfect for both primary and secondary containment applications.

XR-5® is a coated polyester reinforced membrane developed to contain and protect against acids, oils and methane. XR-5 is used as both a primary containment and secondary containment lining material. It offers excellent chemical resistance, superior UV resistance, and better tensile and puncture resistance compared to HDPE membranes.

XR-5 is also available in a formulation that is NSF-61 approved for potable water. This high strength, and highly puncture and tear resistant material offers more flexibility and performs better than any other membrane in potable water applications.

Superior
Strength

Scrim reinforcement makes XR-5 stronger than HDPE film that is twice as thick.

Anti
wicking

XR-5 doesn't have wicking issues like other reinforced membranes.

UV
Resistance

Superior UV resistance over HDPE.

NSF-61
Certified

Certified for use in potable water applications.

Since 1972 we have been the industry leader in providing flexible PVC corrosion resistant liners. Flexible liners are a cost effective alternative to bonded Linings and coatings. Flexible PVC liners are used in plating tanks, chemical tanks, storage tanks, waste water treatment pits, secondary containment, cooling towers, pits, sumps, solar heated water storage tanks, or anywhere liquid containment or corrosion protection is desired.

Industries served include metal finishing, plating, anodizing, aerospace, oil and gas, mining, municipal water treatment, and food and agriculture. Witt offers a variety of materials such as Koroseal®, Spectra Blue® and Exceline®. Witt Lining Systems also offers alternatives to PVC, custom fabricating Teflon®, Kynar® PVDF, and XR-5® liners.
