PIPE BURSTING is the ideal technique to use for the rehabilitation and replacement of utility lines such as gas, water, sewer, telephone, and power. PIPE BURSTING efficiently bursts clay, concrete, cast iron, and PVC pipe. PIPE BURSTING is the ideal technique to use for the rehabilitation of ageing utility systems located in congested areas such as municipalities, city centers, and manufacturing or industrial plants for several reasons. The process involves very little disturbance caused by open trench excavation. A constant-tension winch guides the pipe bursting tool through the host pipe. The rear expander displaces host pipe fragments into the surrounding soil, while the tool pulls in the new polyethylene pipe. In addition, this process generally costs less than the conventional replacement through the open cut method.
