Slip Lining

Application
A trenchless method of installing new factory-manufactured pipe and service connections inside existing sewer, water and commercial lines. Accomplished by pulling a new liner pipe into the existing pipe, creating a slight decrease in the inside diameter. Best for pipes ranging from 8 to 96 inches in diameter.

Advantages
Sliplining can be performed rapidly, without disturbing adjacent services or requiring bypass pumping. It makes it possible to repair long lengths of pipe with minimal disruption. Because the liner is structurally sound, it solves problems related to leakage and structural deterioration.

In the sliplining process, a winch cable is inserted through the existing line and then attached to the front of the new liner. The new liner pipe is then pulled into the existing pipe, and the new liner pipe reconnected to the system. If needed, the void between the new and old pipes can be filled by grouting.

Products and services may be limited by geographic region and project
scope.
