Product Overview

The patented Poly-Triplex® Liner System is a cured-in-place structural liner that is designed to provide one hundred years of structural integrity and a legacy of protection for your collection system.

Utility departments and engineering firms over the U.S. and Canada rely on our Poly-Triplex system to rehabilitate varying types of structures from sewer manholes and pump stations to catch basins and corrugated culvert pipe. The liner and installation process results in a cured-in-place structural liner that provides a water and chemical barrier to further deterioration and infiltration. The liner becomes an integrated composite bonded to the host structure. Because of the liner’s excellent structural properties it can be used in extremely deteriorated conditions. Because of its non-porous properties, it can be installed in structures with active infiltration.

Poly-Triplex is a three-layered fiberglass and epoxy system that contains a vital internal non-porous membrane. Once saturated at the jobsite, the liner is cured-in-place using our patented system of air pressure and steam, forming a unified composite bonded to the host structure. The process uses the existing structure as a mold and the liner is pressurized into the pores, cracks and crevices of the structure surface.

The resin bond prevents the liner from being pushed off from groundwater infiltration. The Internal non-porous membrane, encapsulated in the center of the composite, eliminates pinholes and provides a permanent barrier to gas penetration through the liner, halting chemical attack of the host structure, as well as providing a permanent barrier to prevent infiltration of groundwater into the collection system.

Cured in Place Structural Liner Components

Poly-Triplex® Liner design uses three layers of structural materials that are comprised of five separate components.

Layer #1 – Structural Fiberglass
This component is saturated with 100% solids epoxy resin and bonds to the host structure.

Layer #2 – Non-Porous Inner Membrane
This layer contains 3 critical components, one non-porous membrane with felt fibers embedded on both sides, creating a mechanical bonded between the membrane and the other materials. This layer is the most vital part of the rehabilitation process, eliminating any pinholes, thereby providing a permanent barrier to infiltration, ex-filtration and gas penetration.

Layer #3 – Structural Fiberglass
This component is saturated with epoxy resins and once cured, provides protection to the internal non-porous membrane and provides a smooth interior surface to the lined structure.
