Protect concrete pipes, tunnels, wet wells, and lift stations from corrosion by specifying they be made with T-Lock. During casting, concrete flows around the polyvinyl chloride sheeting's full-length, molded-in T-ribs to permanently lock the liner into place as part of the substrate. Arrow-Lock, T-Hab, and Wrap & Cap are for rehabilitating previously unprotected or corroded concrete.
