Ameron’s T-Hab system is a trenchless sewer rehabilitation process that uses proven T-Lock PVC liner—the most effective way to fight the corrosive effects of sewer gases.

T-Lock is placed over a collapsible form that travels inside the corroded pipe or tunnel. The form is then expanded, pushing the T-Lock against the surface of the host pipe. A specially engineered grout is then pumped into the annular space between the T-Lock lining and the concrete surface. projecting T-shaped ribs in the liner "lock" into the grout, rehabilitating the sewer line for many years of service.
