Pipe bursting for sewer line replacement
Pipe bursting pulls a new pipe, usually high-density polyethylene, through the old sewer line while a bursting head breaks the old pipe outward. It replaces the line through two small pits and works where lining can't, such as collapsed or undersized pipe.
Pipe bursting is the trenchless option when the old pipe is too damaged to line. Because it doesn't rely on the old pipe's shape, it can handle collapsed sections and can upsize the line.
It needs a pit at each end, a clear route without other utilities crossing close to the sewer, and soil that allows the old pipe fragments to be pushed aside.
Signs you need pipe bursting
- A camera shows collapse or severe deformation
- Repeat backups in pipe too damaged to line
- Orangeburg or badly broken clay pipe

Pipe bursting: common questions
Pipe bursting or lining: which is better?
Lining suits cracked or root-damaged pipe that still holds its shape; bursting suits collapsed, deformed or undersized pipe.
Can pipe bursting fix a sag?
Sometimes. Unlike lining, bursting can modify the grade in some conditions; severe sags may still need excavation.
What rules pipe bursting out?
Other utilities too close to the sewer, some soil conditions, and lines without practical access at both ends.
