Robotic Cutting

1 min read Updated 6 Jul 2026 DrainSpy Brisbane
In short Using remote-controlled cutting robots inside a drain to grind away obstructions — protruding junctions, hard scale, concrete, failed liners or intruding connections.

Cutting robots carry air- or electric-powered grinding heads through the pipe under camera guidance. They remove obstacles that jetters and eels cannot: concrete slurry that entered during building works, protruding junction pipes, hardened scale and botched previous repairs.

Robotic work is precise but slow, and is typically priced by time and complexity — a good reason to confirm the obstruction on CCTV first.

What Is It For?

Removes hard obstructions and prepares pipes for relining without excavation.

Where You'll Find It

Deployed in drains from around 100 mm upward, via standard access points.

Common Problems

  • Slow progress through very hard concrete
  • Limited manoeuvrability in small or tightly bent house drains
  • Requires skilled operators to avoid pipe damage

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.
