The work specified under this document provides for the rehabilitation of existing sewer pipelines and culverts using PVC ‘Expand-in-Place’ trenchless technology. The process consists of installing a thermoformed PVC pipe liner inside an existing sewer or culvert (Host Pipe) from manhole to manhole or from one access point to the other. When installed, the liner will be a seamless, joint-less, solid wall PVC pipe lining that tightly conforms to the interior contours of the original host pipe.
