Concrete Cost per m² Calculator (Australia)

Construction · Australia

Concrete cost per m² — slab pricing the honest way.

Size up a slab in metres, pick the grade and thickness, add the bits that actually cost money — reo mesh, formwork, labour, pump hire — and get a real cost per square metre, not a guess off a forum.

// note Estimate only. AU concrete prices vary by metro/regional location, batch plant distance, and access. Standard 6×2.4 m mesh sheets assumed (≈14.4 m² each, 10% lap waste). Confirm with your concreter and supplier — pump access, weekend pours and reo upgrades shift the number quickly.
