Pipe bursting is a form of trenchless pipe replacement in which an existing underground pipe is replaced with a completely new pipe but without the disturbance and cost of excavating a trench from the surface. The process typically involves the insertion of a tool into the existing pipe that has a maximum diameter that is slightly larger than the existing pipe. This tool is used to break the existing pipe into pieces and to displace the pieces and neighboring soil outward into the surrounding ground while a new pipe is installed behind the tool.
