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
- Match the breaker to your machine, e.g. breaker for R22, breaker for R18 or the R32 breaker hammer.
- Breakers need auxiliary hydraulics. Machines with higher flow, like the R18 PRO (41.4 L/min piston pump), run them strongly.
Technique
- Work from the edge. Start near an edge or crack rather than the middle of a slab.
- Keep the tool square. Hold the breaker at 90° to the surface and apply steady down-pressure.
- Short bursts. Break in short bursts, moving if the material doesn't crack within a few seconds.
- Don't pry with the tool. Levering with the chisel damages it.
- 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.
