Most concreters get the basics down but lose money on two things: underestimating waste and forgetting to charge for difficult site access. A cheap job can turn expensive fast if you need a concrete pump because the truck can't get close, or if you have to cart away an extra half-dozen barrows of soil by hand. This template helps you price for the job as it is, not as you hope it will be.
How to Price Your Slab: M3, Labour, and Waste
Your main cost is the concrete itself, priced per cubic metre (m3). An N25 mix from a supplier like Boral or Hanson will run you about $300-$350 per m3 delivered. Always add a waste factor of 5-10% to your total volume to account for uneven ground and spillage. For labour, you can charge a day rate per person or a square metre rate for the whole job, from prep to finish. A typical rate for a simple slab finish is $50-$85 per square metre, including labour and materials. Always factor in reo mesh like SL72 from Bunnings Trade at around $100 per sheet.
What Gets Left Off a Concrete Slab Quote
The biggest mistake is forgetting pump hire. If the truck can't reach the pour area, you'll need a line or boom pump, costing anywhere from $500 to over $1,000. Another forgotten cost is soil and rock disposal. Tip fees are high, so calculate the volume of spoil accurately and charge for it. Always check if a council permit is needed, as this adds time and cost. Finally, make sure your work meets the standard. All residential slabs must comply with AS 2870, which dictates things like slab thickness and reinforcement placement. Quoting to standard protects you and the client.

Frequently Asked Questions
You need to overlap reinforcement mesh by at least two full squares to ensure structural integrity and prevent cracks. For SL72 mesh, with its 200mm grid, that means a 400mm overlap. Factor this into your total sheet count when ordering from a supplier like CSR, otherwise you'll come up short on the day.
Use N20 (20MPa) for footpaths and basic shed slabs. For anything structural like a house slab or a driveway that needs to support vehicles, you must use N25 (25MPa) or stronger. The price difference is minimal for the extra strength required. Most engineers will specify N25 as the minimum for residential slabs under AS 2870.
Yes, always. Control joints manage natural cracking as the concrete cures. For a basic broom-finish slab, saw cuts are the cheapest method. They should be cut within 24 hours of the pour to a depth of about one-quarter of the slab's thickness. Omitting them from the quote means you'll either wear the cost or have to ask the client for more money later.
