Worst Contributors of Infiltration and Root Intrusion
No Homeowner Involvement
INTERfit USA is a full main wrap (360°) Cured-In-Place (CIP) lateral connection seal installed from the sewer main during live flow using the nearest manhole. Developed in 2003, INTERfit forms smooth, lipless transitions with the existing pipe or liners, leaving a minimal reduction in cross sectional area. INTERfit can be used in the widest range of junction configurations, and is ASTM 1216 compliant.
