Road base is the workhorse that sits under driveways, slabs, paths and pavements. The most common type is DGB20, and at Elite Sand & Soil we supply it in natural, recycled and cement-stabilised forms. Here’s how to pick the right one.
What is DGB20 road base?
DGB20 (dense-graded base, 20mm) is a graded mix of crushed stone and fines that compacts into a strong, stable layer. Its angular particles interlock to form a solid, long-lasting base — which is why it’s the standard material under driveways, slabs, paths and pavements.
Natural vs recycled — the main choice
Natural DGB20 is virgin quarry-sourced road base that meets RMS specifications, with consistent grading and strong compaction. It’s the pick for:
- Commercial site base prep
- Slab and pavement works
- Council and government jobs
Recycled DGB20 is a cost-effective, environmentally friendly base made from crushed, screened recycled concrete. It delivers excellent compaction and stability while reducing landfill waste — ideal for:
- Driveways and slab preparation
- Temporary roads and access paths
- General pavement base under bitumen, asphalt or turf
Need extra strength? Stabilised road base
For engineered, load-bearing bases we also blend road base with cement:
- Stabilised Natural Roadbase — virgin DGB20 stabilised with cement for engineered-grade pavement and slab base: council-specified roadworks, commercial slab or kerb prep, and carpark bases.
- Stabilised Recycled Roadbase — recycled road base blended with 2–5% cement for enhanced structural support: slab prep, footings and pads in soft soil, and low-cost road and driveway base.
Which should I use?
- Natural DGB20 — council, commercial and government jobs that need spec compliance.
- Recycled DGB20 — driveways, paths and general base; the economical, eco-friendly choice.
- Stabilised (natural or recycled) — when you need extra strength, an engineered base, or you’re building over soft soil.
