The resins used are typically polyester for mainline lining and epoxy for lateral lines. Since all resins shrink (epoxy resins shrink far less than poly and vinyl ester versions) and because it is impossible to bond to a sewer line with fats, oils, and grease present, an annular space is always created around the new CIPP liner, between it and ...
