Full driveway material list — sub-base, sand and surface (gravel, block paving, concrete or tarmac) for your driveway size.
Enter the driveway length and width, pick the surface type, and set the sub-base depth (150 mm / 6 in is typical where cars park). The tool returns the compacted crushed-stone sub-base (called MOT Type 1 in the UK, “crusher run” or “GAB” in the US) in tons/tonnes, plus the surface material — loose gravel, asphalt (tarmac) or block pavers.
| Layer | Depth |
|---|---|
| Sub-base (crushed stone) | 150 mm / 6 in |
| Loose gravel surface | 50 mm / 2 in |
| Asphalt / tarmac | 50–75 mm / 2–3 in |
| Bedding sand under pavers | 30–50 mm / 1–2 in |
A 5 m × 3 m drive = 15 m². A 150 mm sub-base = 2.25 m³ ≈ 4.5 tonnes of MOT Type 1. A 50 mm gravel top = 0.75 m³ ≈ 1.2 tonnes.
Tip: compact the sub-base in layers with a plate compactor (“wacker plate”) and lay a weed membrane under gravel so the surface stays clean and stable.
For cars, 150 mm of compacted MOT Type 1 is the usual minimum. For heavier vehicles or soft ground, go to 200 mm or more.
Standard 200 × 100 mm blocks work out at about 50 per square metre. Always order a few percent extra for cuts.
Yes — block paving and gravel both need a solid edging to stop the surface spreading. Budget for edge kerbs or restraints separately.
In many areas a driveway using permeable materials, or one that drains to a soakaway, needs no permission, while non-permeable surfaces draining to the road often do. Always check your local rules first.
Sometimes, if the existing base is sound and levels allow, but it is usually better to excavate and lay a proper sub-base for a long-lasting result.
