Drainage Rock Gold Coast

What Are Drainage Aggregates?

Drainage aggregates are crushed stone products, sized and graded to let water move away from structures and planted areas. They are made from tough rock, and designed to resist clogging or settling. Think of them as a gravel freeway for water, keeping soil stable and preventing puddles where you don’t want them.

Why Are Drainage Aggregates Essential For Water Management And Stability?

Use the right drainage material and water flows where it should. Ignore it and you get erosion, waterlogged soil, and headaches for pipes and retaining walls. Proper drainage reduces repair bills, keeps landscapes healthy, and keeps civil structures behaving themselves. Short version, it saves time and money later. Long version, you’ll sleep better.

We offer a wide selection of drainage aggregates to suit different jobs. Particle sizes include 7 mm, 10 mm, and 20 mm. Pick finer material for bedding and filter tasks, larger stone where free flow and strength matter. We also have intermediary and custom blends available for specific site needs.

Meta-greywacke, often called blue metal, is a durable, angular rock. Its shape helps pieces lock together. That creates a stable but porous layer, great for heavy-duty drainage or structural fills. It’s the workhorse material when you need toughness and performance.

Crusher dust is a fine, compactable material. It’s ideal for pipe bedding and subsoil drainage. It compacts well, provides support, and still lets water through at a useful rate, while helping stop fine soil washing into pipes.

Choosing the right particle size is a key decision. 7 mm for finer bedding and filtration jobs. 10 mm where you need a balance of flow and compaction. 20 mm for rapid drainage applications like French drains and behind retaining walls. Sizes affect permeability and stability. Sounds obvious, but the wrong size can cause problems down the track.

Our aggregates are tested and graded to ensure they stand up to loads, while still letting water pass. They perform consistently, under heavy traffic or quiet garden spots. They last, plain and simple.

Nucrush products comply with the relevant Australian standards for civil construction. That means engineers can specify them with confidence, and projects meet regulatory expectations. No guesswork, just certified materials.

We source locally where practical, to reduce haul distances and environmental impact. Nucrush supports recycling initiatives and applies eco-minded practices across our operations. It’s not flashy, but it matters.
