Pipe bursting is receiving more and more attention as a viable alternative to open trench replacement. Pipe bursting can be used for pipes ranging in size from 2 to 30 inches and new bursting tools and techniques are being developed that will increase the upper limit to four and even five feet.

The tool contains scoring wheels, a cutting blade and a spreader. The existing steel pipe is scored, cut and spread apart rather than shattered or otherwise destroyed.
