Crusher dust: the finishing layer that makes the job easy
Fine crushed rock that screeds flat, compacts tight and drains well. The go-to bedding layer for pavers, tanks and synthetic turf.
What is crusher dust?
Crusher dust (also called cracker dust or blue metal dust) is the fine material screened out when rock is crushed, from about 5 mm down to dust. It spreads and levels easily, compacts into a firm surface and still lets water through, which is exactly what you want directly under pavers, slabs and tanks.
Common uses
- Bedding layer under pavers and stepping stones
- Pads under water tanks and pool shells
- Base for synthetic turf installs
- Backfilling trenches, pipes and cable runs
- Binding layer over road base for a tight finish
Crusher dust or sand for paving?
Both work as bedding, but crusher dust locks up firmer under compaction and is less attractive to ants. Most landscapers around Sydney bed pavers on 20 to 30 mm of screeded crusher dust over a compacted road base.
How much do I need?
Allow about 1.6 tonnes per cubic metre. A 25 mm bedding layer uses roughly 40 kg per square metre, so a 20 m2 paved area needs around 0.8 tonnes.
Order a little over rather than under: leftover crusher dust always finds a use, and short loads cost more per tonne. Call 1300 935 483 to check quantities.
