All Aggregates
From roadbase and blue metal to scoria and recycled materials, our aggregates range covers every base — literally. Whether you're preparing a driveway, laying drainage, constructing under-slab fill, or building up a pathway, Melbourne Garden Supplies stocks the crushed rock and aggregate products Melbourne landscapers, builders, and DIYers rely on. All sold by the cubic metre and available for bulk delivery across Melbourne.
Aggregates cover everything that goes under, around, or through a landscaping or building job — roadbase for driveways and slabs, scoria for drainage and garden beds, recycled options where budget or sustainability matters.
We deliver aggregates across Melbourne by the cubic metre from our Altona yard, sourced across Victoria rather than from a single quarry, so we can match the material to the job.
Roadbase vs recycled roadbase
20mm Roadbase is virgin crushed rock blended with fines for strong compaction — the standard choice for driveways and under-slab prep. Recycled 20mm Roadbase is made from crushed recycled concrete and masonry and compacts just as reliably, at a lower price point.
Scoria
20mm and 7mm Scoria are lightweight, porous red volcanic rock — not crushed rock, but a common companion to it in drainage trenches, French drains and garden bed drainage where permeability matters more than compaction strength.

Crushed rock Class 3 20mm is a versatile roadbase product suited to general sub-base and fill applications, offering a more economical alternative to Class 2 where engineered load-bearing strength isn't required.

Crushed rock Class 2 20mm is a high-quality roadbase engineered to Australian standard specifications for pavement and sub-base construction, offering superior compaction and load-bearing strength.

20mm Aggregate is a coarse, crushed blue metal stone suited to larger drainage projects, concrete work, and heavy-duty ground cover where strength and durability are priorities.

14mm Aggregate is a mid-size crushed blue metal stone used widely in construction for concrete production, drainage works, and as a durable decorative ground cover.

7mm Aggregate is a clean, crushed blue metal stone with consistent particle size, commonly used in concrete mixes, drainage applications, and as a decorative or functional ground cover.

20mm Scoria is a coarser grade of lightweight red volcanic rock, well suited to larger-scale drainage work and decorative garden applications where a chunkier texture is preferred.

7mm Scoria is a lightweight, porous red volcanic rock, prized in garden beds and drainage applications for its excellent water permeability and natural colour.
5mm Dust is a fine crushed rock product used as a top dressing, paver bedding layer, or binding material in pathway and paving construction.

Recycled 20mm Roadbase is a crushed rock alternative made from recycled concrete and masonry, offering the same reliable compaction performance as virgin crushed rock at a lower cost.

20mm Roadbase is a crushed rock product blended with fines for excellent compaction, making it the standard choice for driveways, under-slab preparation and sub-base work across Melbourne properties.
