Crusher Dust is a compact, fine rock particle aggregate.

Crusher Dust can be used as a topsoil to improve water retention, a foundation for pavers and driveways, and a filler for fence posts and trenches, among numerous other things. It is a compact, ultra fine rock particle aggregate that’s been excavated and refined in a quarry using crushing and screening machinery.

While this product boasts similar properties to gravel, they’re not one and the same. It has been put through an artificial refinement process to crush—or break down—the larger chunks of rock.

The result is a grey, finely ground powder or dust-like aggregate. Each particle may be as small as 1mm in diameter, hence the inclusion of the word ‘dust’. On average diameters range from 1mm to 5mm.

Is cracker dust the same as crusher dust?

Yes, cracker dust is the same as crusher dust. Cracker dust is a term often used by builders or operators in the civil construction industry.

Can you use it in your garden bed?

Yes, it can be used in your garden bed. It can be used on all garden plants and will act as a fantastic fertiliser and soil improver because it increases the mineral content of the soil.

How to Lay Crusher Dust?

Laying down crusher dust is a fairly straightforward task:

• Use a rake or push broom to spread the aggregate over the desired area evenly
  • Ensure you fill the low-lying areas and don’t leave any section exposed
  • Rake in the same direction as the topsoil (if present).
• Lightly wet the crusher dust to allow it to compact and prevent it from blowing away
  • Avoid applying crusher dust on a windy day if possible
• Use a vibrating plate or smooth drum roller to compact the aggregate

Typically trucked in bulk, it can be bought by the loader.

Loading Weights

A full load weighing 12 tons is equivalent to about 6 cubic metres which could cover 60 square meters at 10cm deep. The truck will dump it on site in a pile. It can be applied by hand or machine.
