The lateral connection is the point where a lateral sewer line from a home or business meets the main sewer line. Lateral connection rehabilitation is accomplished using techniques like grouting and cured-in-place pipe (CIPP). Following an inspection, the cause of the fault can be identified, and the most effective lateral rehabilitation technique can be chosen. A bad lateral connection may cause the joint to open, allowing soil and tree root intrusion as well as infiltration and exfiltration.
