The Interfit cured-in-place (CIP) lateral sealing system rehabilitates and seals lateral connections to lined sewer mains, permanently eliminating infiltration and root intrusion. Depending on lateral defects and bends, the proprietary system extends from 1 in. to 20 in. into the lateral sealing three problem areas:A) the annular space between a main liner and the host pipe, B) the lateral connection, and C) the lateral's first joint.
