NO-DIG
Hydrostatic pipebursting machinery for in-place underground pipe replacements without need for digging along the length of the pipe.
Proper maintenance of water pipes is key to avoiding leaks and loss of non-revenue water. NO-DIG has developed a hydrostatic pipe bursting machinery for underground pipe replacement. The machine replaces the existing pipeline by first pushing a solid steel rod through the pipe via two excavation points. Once the rod has been inserted along the length of pipe between the two excavation points, a bursting head is lowered into one end and connected to the steel rod. A replacement pipe made of polyethylene is then connected to the bursting head. Using static force, the bursting head and new pipe are pulled through the existing pipe, thereby displacing it. This process eliminates the need to dig up the ground along the entire pipe system.
