Sliplining involves lining with PE pipes in existing pipelines. Aarsleff applies sliplining for all types of pipe. Whether it is sewer, water, gas or process pipes is not important, as long as a reduction of the cross section is acceptable.

Prior to implementing the rehabilitation we excavate launch and exit pits. In addition we excavate all laterals, valves and the like. 

When all excavations are finished and the points of junction have been exposed, we either push or pull the long fuse-joined PE pipes into the host pipe.

We then execute all connections and restores all excavations.

The cavity space between the new and the old pipe is injected so that the new PE pipe is firmly secured.
