Main/Lateral Connection Liner with Resin Putty Mainline Portion

摘要

An apparatus for repairing a junction between a main sewer pipe and a lateral sewer pipe comprises a tubular portion having opposite first and second ends. A collar extends outwardly from one of the first and second ends of the tubular portion. The tubular portion and the collar are formed of a curable, waterproof putty, such as an epoxy or silicate putty. The putty may also be a resin, such as a thermoset or other curable resin. The apparatus is positioned at the pipe juncture to prevent the migration of water through a damaged section of the pipe.
