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

How Pipe Bursting Works

Pipe bursting uses a bursting head and pulling equipment to open a path through an old sewer line. The head fractures the existing pipe and moves forward through the soil. A new pipe attaches behind the head, so the replacement follows the old route.

Access points allow the equipment to reach the buried line. The work team checks the line's route, pipe condition, depth, and connections before choosing this method. Sewer Camera Inspection can show breaks, roots, or crushed sections that affect the repair plan.
Pipe bursting can limit damage to lawns, driveways, and other surfaces. The method still needs suitable soil, access, and a clear path. A blocked route, unstable ground, or nearby utility can change the repair approach.

Expert Note
When we assess Pipe Bursting, we inspect the sewer route and check each connection point. We look for access limits, nearby utilities, and conditions that could stop the new pipe from following the old path. Our team also checks the finished line for proper flow and secure connections.
Pipe Bursting in Practice: A Real-World Example
A homeowner has a cracked sewer line beneath a paved driveway. Pipe bursting may allow the old line to be replaced through access points, which can reduce the amount of driveway excavation.
