Pipe Bursting

The Problem:

As cast iron gas mains age corrosion deteriorates the pipe wall, additionally the old cast-iron lines become brittle and can crack, especially in the winter when the earth thaws and refreezes, allowing pipelines to shift up and down. Gas main failures can be catastrophic resulting in loss of life, property damage, and disruption to the public right of way.


Pipe bursting is a trenchless method that replaces an existing pipe with a new pipe of the same or larger inner diameter without the need to excavate a trench. Fracturing the old cast iron pipes and installing a new thermally fused plastic pipe can be accomplished easily and reduce excavation by over 90% on average.
