Pipe Bursting

1 min read Updated 6 Jul 2026 DrainSpy Brisbane
In short A trenchless replacement method where a bursting head is pulled through the old pipe, shattering it outward while dragging a brand-new pipe into the same alignment.

Pipe bursting needs only small entry and exit pits. A cone-shaped bursting head, winched or hammered through the old pipe, fractures it into the surrounding soil while towing new HDPE or similar pipe behind it.

It suits pipes too collapsed or deformed to reline, and can even upsize the pipe diameter. It is less practical where many junctions connect along the run, since each must be excavated and reconnected.

What Is It For?

Replaces failed pipes along the same alignment with minimal excavation.

Where You'll Find It

Between two access pits on runs without frequent branch connections.

Common Problems

  • Every junction on the run needs excavation to reconnect
  • Ground displacement can affect nearby services
  • Not suited to collapsed pipes with lost alignment

How DrainSpy Brisbane Deals With It

A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
