Triplex Liners are manufactured by McNeil Technologies, provided and installed by Infrastructure Rehabilitation USA, Inc. Triplex Liners are composed of two layers of fiberglass and a non-porous membrane. This multi-layered system of materials supplies structural strength to the host structure and stops further infiltration. The rehabilitation process using the Triplex Liners is detailed and uniquely customized to fit each structure. Each individual structure is inspected by Infrastructure Rehabilitation USA, Inc. and exacting measurements are recorded along with thorough field notes. Our installation crew gains a complete understanding of each structure’s needs before the liner is put into production. A custom liner is then fabricated for each structure. At the job site, the structure is high pressure cleaned and etched. Pipes are trimmed and grouted as needed. Benches at the bottom of the structure are rebuilt as needed and a bridge platform is placed just over the invert channel allowing for uninterrupted flow during the installation. The liner is then completely saturated with epoxy resin and lowered into the structure. Once the liner is in place, it is promptly inflated via an internal inflation bladder using both steam and air pressure. The liner will bond to a wet or dry surface. After curing is complete, the inflation bladder is removed, laterals are reopened and the bridge over the invert channel is removed. The entire installation process takes approximately 4-6 hours from start-to-finish, and sewage flow continues uninterrupted.
