Lateral liners, like mainline CIPP, can be used with hydrophilic materials to prevent ground water from infiltrating into the lateral pipe. Lateral CIPP also requires the same quality installation and a trained inspector to observe, verify, inspect, document and test the installation of a lateral rehabilitation liner.
Cured-in-Place Pipe (CIPP) lateral lining is a technology that rehabilitates existing lateral pipes while minimizing disruption to yards, sidewalks and driveways. CIPP lateral lining is appropriate when the host pipe has experienced cracks, fractures or holes but has generally maintained its original shape.
Repair by lining a portion of the lateral pipe or the entire lateral pipe and also lining the main/lateral connection
Repair by sealing the main/lateral connection by use of hydrophilic gasket or paste materials.
Trenchless cleanouts are an alternative to digging, shoring, and using trench boxes for installing a lateral cleanout. Cleanouts typically can be installed in two hours with a small footprint and restoration is performed in the same day.
The method consists of locating a lateral pipe and utilizing a vacuum excavator to make a 20-inch hole exposing the lateral pipe. A tapping saddle and riser pipe are remotely attached using a water activated adhesive as the saddle is inserted into the bore-hole and snapped onto the lateral pipe. A leakage test is typically performed before the lateral pipe is cored to complete the installation.

The RehabZone would not be possible without the generous contributions of industry leaders, companies and organizations that share UIC’s vision to set standards for the assessment, maintenance and rehabilitation of underground infrastructure and to assure the continued acceptance and growth of trenchless technologies.
