Liner Systems

Justrite high-strength industrial coatings bond to any substrate, including geomembrane and high-density polyethylene (HDPE) containment liners, to provide virtually maintenance-free containment that will not leak.

Ethylene Polymer PVC with Elvaloy® Technology Quick Overview

  • Excellent stability, with low thermal expansion-contraction properties
  • High-strength, chemical-resistant grade for maximum protection to high temperatures and a broad range of chemicals including acids, oils and methane
  • Formulated for long-term outdoor exposure to UV rays
  • Florida Department of Environmental Protection Agency approved for secondary containment

PolySeam® Liner Attachment System (Patent No. 8,361,261 B2)

System Highlights

Exclusive PolySeam liner attachment system offers a faster, cost-effective alternative to traditional batten bar attachment. When used in conjunction with our Ethylene Polymer PVC with Elvaloy® Technology Geomembrane or HDPE Containment Liners, the patented PolySeam system replaces the maintenance and repairs needed to maintain integrity of the batten bar method of attachment—for a virtually maintenance-free system! Installs faster and is more durable than containment liners alone, saving thousands of dollars in installation costs, and it installs in the most extreme conditions.

  • Delivered to your site and then cut to desired length for seaming application.
  • Sections are seamed into place using traditional welding methods.
  • Attachments are made from HDPE or Ethylene Polymer PVC with Elvaloy® Technology Geomembrane to tank ring walls, wall, pipe supports or any other penetration.
  • Once liner transition strip is in place, the existing containment liner system is attached using our spray applied coating system to the containment penetrations.
  • Note: All bonding surfaces will need to be cleaned, potentially blasted and primed prior to application.

Tank Farm Containment Liner Systems

Ethylene Polymer PVC with Elvaloy® Technology Geomembrane liner material is well-suited for large installations, i.e. covering approximately 215,000 square feet, such as a tank farm with 2 tanks holding 3-million gallons of diesel fuel.
