Overview of Lateral and Main/Lateral Connection Lining and Sealing Technologies

The intent of this document is to provide information to the public on lateral rehabilitation and sealing options. In some areas, the use of lateral lining and sealing technologies are not specified in plumbing codes. These codes did not anticipate the use of lining or grouting for lateral pipes, resulting in the only alternative being costly excavations and disruption to private property and the public.
