20mm Crushed Rock Road Base - Brown

Our 20mm Crushed Rock Road Base is a brown, general-purpose crushed rock with fines, designed to compact firmly and provide a strong, economical base for driveways, rural access areas and landscaping projects.

This product is a 20mm NDCR (Non-Descript Crushed Rock). It is not manufactured to a Class 3 specification, which helps make it a more affordable choice for everyday applications where a specified Premium Class 3 material is not required.

The blend of 20mm crushed rock and fines helps the material bind together when correctly laid, moisture-conditioned and compacted, creating a firm and durable surface.

Why choose 20mm Road Base?

It is our best-value everyday crushed rock for most general driveway and base applications. Its natural brown colour suits rural and landscape settings and provides excellent value where colour matching to an existing blue-grey driveway is not important.

Ideal for:

• Driveway construction and repairs
• Resurfacing brown or natural-coloured driveways
• Rural access areas
• Shed and slab base preparation
• Paths and landscaping
• General compactable base work

Need a heavier foundation?

For new driveways, deeper bases, soft ground, gateways and farm tracks, our 40mm Crushed Rock Road Base provides a coarser foundation layer. It can then be topped with 20mm road base to create a finer finished surface.

Want a premium blue-grey finish or Class 3 specification?

Choose our 20mm Premium Class 3 - Blue Crushed Rock. It is a classified blue-grey crushed rock produced to controlled grading requirements and is the better option for matching existing blue-grey driveways or where a project specifically requires Class 3 material.

Which crushed rock should I choose?

20mm Brown Road Base
Best-value general-purpose option for most driveway and base jobs.

40mm Brown Road Base
Best for deeper foundations, soft ground, farm tracks and heavy-use areas.

20mm Premium Class 3 Blue/Grey
Best for matching existing blue-grey driveways, customers wanting a more refined finish, or jobs specifically requiring Class 3 material.

Please note: Crushed rock is a natural quarry product, so colour and appearance can vary slightly between loads. NDCR products are general-purpose quarry materials and are not Class 3 specification products. Class 3 contains fines by design to assist compaction. Where material is required for an engineered, council or other specified project, customers should confirm the required material specification before ordering.
