Aggregate Supplies for Long-Lasting Foundations

Every solid project starts with a strong base. Whether you’re putting in a new driveway, preparing a slab or working on a bigger construction job, the right aggregates make all the difference. At Coastal Sand Soil & Mulch, we supply aggregates across Hervey Bay and the Fraser Coast, including roadbase and crusher dust that compact down for strength and stability.


Some of our aggregates are made using crushed and recycled materials, helping reduce costs while cutting down on waste. That means you get a dependable product that also does its bit for the environment. Both pickup and delivery are available, so it’s easy to get what you need, when you need it.

Frequently Asked Questions

  • Can aggregates be delivered in bulk?

    Yes, both roadbase and crusher dust can be delivered in bulk straight to your site. Bulk delivery saves time on bigger jobs and ensures you’ve got enough material to work with. If you only need a smaller load, you can pick it up yourself with a ute, trailer or truck.

  • What is crusher dust used for?

    Crusher dust is a popular choice for slab prep, pathways, driveways and filling trenches. It compacts down tightly and provides a smooth surface to build on.


    Just avoid using it as a base for pavers. Roadbase or packing sand are better for that.

  • How do I know which aggregate I need?

    Think about what you’re building. For anything heavy-duty that needs long-term stability, roadbase is usually the right pick. For smoother jobs like slab preparation or trench backfilling, crusher dust works well.


    If you’re not sure, it’s worth asking. The right choice upfront makes the job quicker and prevents problems later.

Crusher Dust & Roadbase Aggregates

Not every job calls for the same material, and choosing the right one up front keeps projects running smoother.


  • Roadbase Aggregates: A mix of coarse and fine particles that bind together when compacted. Great for driveways, house pads, access roads and any area that needs a stable surface under heavy use.
  • Crusher Dust: Made entirely from fine rock particles, crusher dust compacts tightly and creates a smooth finish.


Crusher dust is ideal for slab preparation, pathway prep, driveway prep and trench filling. Crusher dust isn’t the best choice under pavers though (it can make them crack over time). For that, roadbase or packing sand works better. If you’re unsure, you can always drop by the yard or give us a call to talk through the options.
