Pipe Bursting to Repair Sewer Lines
Pipe Bursting is the ideal technique to use for the rehabilitation and replacement of utility lines such as gas lines, water lines, sewer lines, telephone lines, and power lines.

Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional construction trench. “Launching and receiving pits” replace the trench needed by conventional pipe-laying.
Pipebursting may also be used to expand pipeline carrying capacity by replacing smaller pipes with larger ones, or “upsizing.” Extensive proving work by the gas and water industries has demonstrated the feasibility of upsizing gas mains, water mains and sewers. Upsizing from 100mm to 225mm diameter is now well established, and pipes of up to 36 inch  diameter and greater have been replaced.
Pipe Bursting is an effective and affordable way to replace your complete sewer line for a fraction of the cost of a full excavation.
It is possible that some excavation will be needed to access the existing sewer line which also allows our team of Technicians install the outside cleanouts required by city building codes.
Pipe Bursting efficiently bursts clay, concrete, cast iron, and PVC pipe. Pipe Bursting is the ideal technique to use for the rehabilitation of aging utility systems located in congested areas such as municipalities, city centers, and manufacturing or industrial plants for several reasons. The process involves very little of the 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.
