Launching and receiving pits replace the trench needed by conventional pipe-laying.

Pipe Bursting

Pipe bursting is defined as a trenchless replacement method for renewal of deteriorated and undersized pipelines in which the existing pipe is broken, either by brittle fracture or by splitting, using an internal mechanically applied force applied by a bursting tool. At the same time, a new pipe of the same or larger diameter is pulled in replacing the existing pipe.
