An Overview of Slip Lining
Slip lining, also referred to as Cured in Place Pipe (CIPP) is one of the earliest methods of trenchless pipe rehabilitation used to fix pipes that have already been installed. The method involves the insertion of a slightly smaller diameter pipe (carrier pipe) into an existing pipe (host pipe) before mechanically reconnecting services.
What Does the Process Involve?
Typically, we excavate insertion pits that are strategically located and use high-tech equipment to insert a new, factory-made pipe into the host pipe. Depending on the situation, we often install the new pipe without diverting live flow or bypass pumping.
Several different materials can be used for slip lining, but it usually involves a felt-like material that’s impregnated (soaked) with a 2-part epoxy/resin mixture. The new pipe can be installed in two main ways:
- Pull in Place
When the process is complete, we grout the space between the old and new pipe to secure the new pipeline in place. Our experts are well versed in the different installation methods and pipe materials to tailor solutions to your specific conditions.

Why Choose Slip Lining Pipe Rehabilitation?
Slip lining is done for the same reasons most pipeline rehabilitation is performed, stopping corrosion, elimination of infiltration and restoring hydraulics. Slip lining pipes are typically made of materials that are corrosion resistant and can provide leak-free joints. Although the slip line pipe used is typically smaller in diameter, the hydraulics of the system are restored or even improved once the process is complete.
Ideal for sites that are difficult to dig or congested areas, slip lining saves money and provides a strong, new pipeline without the need to replace your entire system.
