FAQ

Concrete slab cost questions

  • How much does a concrete slab cost in Australia?

    A plain reinforced slab or driveway runs roughly $65 to $120 per square metre supplied and poured for basic work, climbing with decorative finishes, pump hire and base prep. A typical 40 to 60m² slab lands around $2,800 to $9,500 all up.

  • What thickness should my slab be?

    Paths and patios are usually 100mm, driveways 100 to 125mm, and shed or heavy-load slabs 125mm or more. Thicker slabs use more concrete and mesh, which lifts the price. Always follow your engineer's spec for structural work.

  • Does the price include excavation?

    The base estimate assumes a reasonably level, prepared site. If you need a site cut, base rock or thickened edges, the real cost rises - a concreter will confirm after a site look.

  • How do I get an exact concreting quote?

    This is a ballpark band. For a fixed quote with your real measurements, a local concreter running Karven can send a branded, itemised quote quickly. Tap Get an exact quote.
