Pipe Bursting to Replace Damaged Sewer Lines.
Under the traditional dig-and-replace method of sewer rehabilitation, a replacement or additional parallel sewer line is constructed by digging along the entire length of the existing pipeline, removing the existing pipe, and replacing it with a new pipe.
In contrast to the traditional method, which requires unearthing and replacing the deficient pipe, trenchless sewer rehabilitation techniques do not require excavation of the existing piping. Instead, these methods use the existing collection system piping as a conduit or host for replacing or rehabilitating the system. In general, trenchless technologies can be implemented through existing openings to the sewer system (such as the manholes) or through smaller insertion pits rather than through excavation along the entire length of the pipe. Because these types of sewer replacement methods do not require extensive excavation, they provide a method of correcting pipe deficiencies with less disturbance, economic impact, and environmental degradation, and they require less restoration than the traditional dig-and-replace method.
General Rooter offers several services for replacing or repairing damaged sewer pipes. The method used depends on your particular circumstances.
We offer the traditional dig-and-replace, where we excavate a trench along the entire length of the existing pipeline. But when appropriate, we may recommend trenchless methods that do not require digging up your yard, driveway, garage floor, or more, requiring less restoration than the traditional dig-and-replace method.
Another technique we commonly use is pipelining, where the sewer pipe is relined with our Cured In Place Piping (CIPP) from your home to the city sewer main without excavation or digging up your basement, slab, floors, yard, landscaping, driveway, or roads.

Pipe bursting, also called in-line expansion, is another trenchless method of replacing damaged sewer pipes. It involves a cable and winch to pull a new pipe through an existing damaged pipe as it is shattered by a bursting head pushing it apart to create room for the new pipe as the surrounding soil is also pushed away.
Sewer pipe bursting is typically used for:
- Replacing pipes without tearing up your yard or home
- Breaking and expanding the existing buried sewer line
- Damaged pipes that are longer than 15 feet
Pipe bursting does not require the use of added chemicals or other contaminants.
