What Is Pipe Bursting?
Pipe Bursting is a trenchless sewer repair method that breaks an old buried pipe apart while pulling a new pipe through the same path. A bursting head travels through the existing line and pushes broken pieces into the surrounding soil. The method can replace a damaged sewer line with limited surface digging.

How Pipe Bursting Works

Pipe bursting uses a pulling machine, a bursting head, and a new replacement pipe. The crew creates access points at selected parts of the sewer path. A cable or rod pulls the bursting head through the old pipe. The head cracks the old material and presses the pieces into nearby soil.

The new pipe connects behind the bursting head, so the replacement follows the old route. The method works best when the existing path has a suitable layout and the surrounding soil can accept the broken pipe pieces. A sewer camera inspection helps show pipe condition, alignment, and connection points before work begins.

Expert Note
When we assess Pipe Bursting, we review the sewer camera findings, access points, and pipe path. We also check nearby connections and soil conditions because those details affect whether the new pipe can follow the existing route. Our team records these findings before selecting a trenchless repair approach.
Pipe Bursting in Practice: A Real-World Example
A homeowner has a cracked sewer line running beneath a landscaped yard. Pipe bursting can open access points near the line, break the old pipe underground, and pull a new pipe along the existing path.
