How it works
The existing pipeline is located and two excavations are dug out. One for the pipeburster unit, and one for inserting the new replacement pipe.
The existing pipeline is removed from the two excavations and the pipebursting equipment is positioned as shown on the sketch.

By hydraulic force, solid steel rods are pushed, one by one, up through the existing pipeline. Upon arrival at the second excavation, the solid steel rods are connected to the bursting head and new replacement pipe.
Thereafter the pipeburster will pull the bursting head into the existing pipeline. The existing pipe, is split and pushed into the surrounding soil, and simultaneously replaced by the new replacement pipe.
When the bursting head arrives at the first excavation, the job is completed.
