🧮 Pavement Calculator

Estimate materials for concrete, asphalt, pavers, or gravel — including depth, base layer, waste, and (for pavers) piece count.

Typical thickness: patio/path 2–4 in, driveway 4–6 in (concrete/asphalt). For pavers, enter paver thickness.

Common: 4–6 in for walkways/patios; 6–8+ in for driveways (gravel/road base).

Pavement Calculator – Concrete, Asphalt, Pavers & Gravel

Plan your patio, pathway, or driveway with confidence. Enter your dimensions, pick a pavement type, set thicknesses for the surface and base, and apply a waste factor. The tool returns volumes for surface and base layers (in both metric and imperial), and for pavers it also estimates the number of pieces needed.

FAQs

Do I need a base layer?
Yes—base layers improve drainage and reduce settlement. Thicker bases are recommended for driveways and poor soil.

How much waste should I add?
10% is common for cutting and irregular edges; use 5% for simple rectangles and 15% for complex shapes.

Can I switch units?
Absolutely—toggle between imperial and metric. Labels will update to the correct units.
