Slip Lining

By inserting a smaller diameter pipe into an existing pipeline, this trenchless method provides a durable, watertight pipeline and increases the structural integrity of the pipe. The space between the host pipe and the new pipe is grouted to further ensure impermeability in large-diameter sewers. This method can usually be installed without bypassing flows and with minimal disruption.

Types of liners:

Segmental PVC or HDPE Slip Liner
A lightweight PVC pipe that combines a high-modular compound with an I-beam profile for a structurally sound pipe.

HDPE Fused Slip Liner
A lightweight, solid-wall, heat-fusible product that provides a durable liner pipe.
