Concrete Driveway Calculator — m, m³, cost
How to use this calculator
Choose a driveway shape — straight rectangle, flared (wider at street), curved (approximate), or custom area — then set the concrete thickness (10–15 cm typical) and waste. Enable optional sections for gravel subbase, rebar/mesh, control joints, and cost breakdown.
Thickness — 10 cm minimum for cars, 12–15 cm for trucks. Subbase — 10 cm compacted gravel. Joints — every 3 m to prevent cracking. Finish — broom (standard), exposed aggregate, or stamped.

How to Calculate Concrete for a Driveway (Metric)
This calculator estimates concrete volume in m³, gravel subbase, reinforcement, control joints, and total cost for driveways. Choose from straight, flared, curved, or custom area shapes. Standard thickness is 10–15 cm per Eurocode 2.
Formulas
Concrete volume = Area × Thickness. Gravel volume = Area × Gravel depth. Control joint length = transverse cuts × width + longitudinal cuts × length. Joint spacing: max 3 m for residential driveways.
Reinforcement Options
Welded wire mesh (2.4×6 m sheets, 14.4 m² each): standard for driveways. Rebar Ø8 or Ø10 mm at 200 mm spacing both ways. Fiber mesh: ~0.9 kg/m³ added to mix.
FAQ
How thick? 10 cm minimum for cars, 12–15 cm for heavy vehicles. Gravel? 10 cm compacted gravel for drainage. Joints? Cut every 2.5–3 m. Depth = ¼ of slab thickness.
