Slip Lining is a trenchless technique used to construct a new pipeline of smaller diameter within an existing pipeline.
Sliplining is similar to pipebursting, except a pipeline smaller than the existing the host pipe.
This method is carried out by the installation of a new pipe, into a larger host pipe. Depending on the application, it may be necessary to grout the annulus gap between the new pipe and the host pipe.
Sliplining can be used to prevent infiltration and rehabilitate structural soundness of a damaged pipe. Sizes of the pipes in which sliplining is applied ranging in sizes of 60mm up to 3.5 metres.
