Old slabs, paths, footings and limestone caprock are common obstacles on Perth jobs. A hydraulic breaker turns a mini excavator into a demolition tool.

Choosing a breaker

Technique

  1. Work from the edge. Start near an edge or crack rather than the middle of a slab.
  2. Keep the tool square. Hold the breaker at 90° to the surface and apply steady down-pressure.
  3. Short bursts. Break in short bursts, moving if the material doesn't crack within a few seconds.
  4. Don't pry with the tool. Levering with the chisel damages it.
  5. Clear as you go. Remove broken pieces with a bucket so you can see what you're doing.

Safety

  • Hearing and eye protection for everyone nearby — breakers are loud and throw chips.
  • Keep people well clear of the work area.
  • Check for reinforcement, services and conduits in slabs before breaking.
  • Some older buildings and materials may contain asbestos — get suspect materials tested and follow WA regulations.

Before you dig: lodge a free enquiry with Before You Dig Australia (byda.com.au) and locate underground services. See Before You Dig in WA.

Limestone caprock

For caprock, try a ripper first — it's quicker when the rock is layered. Use the breaker for solid pieces the ripper can't lift.
