Material and installed cost ranges for gravel driveways, plus the layer system that makes them last.
Long driveways with good access cost less per square metre than short, tight ones with lots of handwork.
Skimping on the base is the #1 reason gravel driveways rut — the base does the work, the top is just the finish.
A 30m × 4m driveway (120 m²) with three 100mm layers — about 36 m³ of material, roughly 57 tonnes:
Use the Cubic Yard Calculator or Gravel Calculator to turn your driveway dimensions into tonnes before talking to suppliers — it makes quotes comparable and prevents over-ordering.
A two-car driveway with three 100mm layers needs roughly 40–60 tonnes depending on length and width. Use the gravel calculator with your exact dimensions.
Plan on a screening top-up every 1–3 years depending on traffic, plus occasional regrading. A good base reduces how often you need to add material.
Gravel is a fraction of the upfront cost, but asphalt lasts longer with less annual maintenance. Gravel is the right choice for a budget build or long rural driveway; asphalt wins for frequent use.
