ABSTRACT:
A conduit lining system and a method for lining conduits, particularly conduits in need of repair. The system includes a longitudinally extending liner, initially transversely curled in a pre-installation position but being capable of becoming uncurled in an installation position to form a longitudinally extending generally cylindrically shaped liner for placement adjacent an interior surface of a conduit to be lined or repaired. The liner has longitudinally extending locking edges which become mutually engaged as a torpedo-shaped member is inserted within the liner, while in the curled pre-installation position, and the member is moved longitudinally therethrough.
