Fold and Form PVC Pipe Lining

Fold and Form PVC Liner is a completely trenchless form of restoration and is used to rehabilitate pipe sections between manholes. The liner is heated, pulled into the host pipe, and reformed with steam and air. Service laterals are reinstated robotically with cutters and a camera. Although the diameter of the line is reduced by the thickness of the liner, the smooth seamless pipe has less friction loss which more than compensates for the diameter change.
