Abstract
A new apparatus for repairing a damaged portion of a pipe includes a liner having a tubular sleeve of resin absorbent material that includes a plastic film laminated to an exterior surface of the sleeve. The plastic film contains resinous material in the liner, and is modified to breech the integrity of the plastic film and expose the resinous material to a junction of a main and lateral pipe. A method of lining a junction of a main and lateral pipe using the liner is also provided.
