Rock Graded at the Source
Our basalt is sourced and graded by us, which means consistent quality, reliable supply and no substitution. Whether you need a single load or bulk supply for a civil contract, call us to discuss sizing, quantities and delivery.
That direct control over the supply chain matters on a job site. You're not waiting on a third party to confirm availability or accept a substitute grade mid-project.
We supply basalt bush rock in multiple grades and sizing, sandstone from on-site stockpile and offer supply to trade and contractors with delivery available across the corridor. If you've been burned by inconsistent supply before, this is a different way of working.
Frequently Asked Questions
What sizes of basalt bush rock are available for supply?
Basalt bush rock is graded and supplied in a range of sizes, from smaller pieces used in garden beds and landscaping through to large boulders suited to structural retaining walls, erosion control and civil works. When enquiring, it's worth confirming whether the supplier grades on-site and what their standard size breaks are, as consistency across a load matters particularly for retaining wall construction.
Can basalt bush rock be delivered, or does it need to be collected?
Most suppliers offer tipper truck delivery, with loads measured in tonnes and costs calculated per load or distance. Minimum order sizes apply, so confirm these before enquiring. Site access is also worth considering — steep blocks, tight driveways or limited turning space can affect what truck size can be used and where rock can be dropped.
What's the difference between basalt bush rock and sandstone for retaining walls?
Basalt is a dense volcanic rock with high compressive strength, making it well-suited to structural retaining walls and heavy-duty applications. Sandstone is lighter in colour, easier to shape and better suited to decorative garden walls and lower-load landscaping. For walls that need to hold significant loads or resist hydrostatic pressure, basalt is generally the stronger choice.
