Instant concrete volume, bag count, and ready-mix estimates for Melbourne projects
Calculate concrete for slabs, driveways, footings, and columns using accurate 2026 Melbourne pricing. Free tool for homeowners, builders, and concreters across Greater Melbourne and all suburbs.
Accurate concrete calculations for residential and commercial projects across Greater Melbourne
Our Melbourne concrete calculator uses industry-standard formulas to compute concrete volume in cubic metres for slabs, driveways, footings, and columns. Whether you're pouring a backyard slab in Dandenong or a commercial floor in Port Melbourne, get the exact quantity you need every time.
Instantly estimate costs based on 2026 Melbourne ready-mix concrete prices. Our tool covers standard 20 MPa up to high-strength 40 MPa mixes and includes estimates for both premix bags and delivered ready-mix trucks from local Melbourne and metro suppliers.
Designed for owner-builders, licensed builders, and DIY homeowners across Melbourne's diverse suburbs — from bayside Brighton to outer growth corridors in Cranbourne and Melton. Supports slabs, driveways, strip footings, and circular piers with full wastage allowance.

Three main concrete pour types used in Melbourne residential construction — each calculated differently in the Melbourne concrete calculator above
The Melbourne concrete calculator computes the volume of concrete needed for any pour type using standard geometric volume formulas. All results are in cubic metres (m³) — the unit used when ordering ready-mix concrete from Melbourne suppliers like Hanson, Boral, and Holcim. For reference on admixture requirements for your mix design, visit our admixture dosage calculator.
Melbourne is classified as a high-reactivity soil zone across many suburbs, including areas of the inner north, western suburbs, and South-Eastern growth corridors. Always obtain a soil report (AS 2870 classification) before designing your footing. Building permits are required from your local council for most concrete works attached to habitable buildings. Visit the Victorian Building Authority for permit and registration requirements.
20 MPa: Garden paths, non-structural pads, blinding layers under slabs
25 MPa: Standard residential slabs, driveways — the most used grade in Melbourne
32 MPa: Structural elements, bayside suburbs with B1 coastal exposure
40 MPa: Commercial floors, tilt panels, structural columns in the CBD and industrial zones
75–100mm: Footpaths, garden paving, paths
100mm: Minimum NCC residential floor — most single storey homes
125mm: Garages and carports with light vehicles
150mm: Driveways subject to truck or caravan loads
200mm+: Commercial warehouse floors, tilt panel industrial sites
Hanson Concrete: Multiple Melbourne metro plants — North, South, East and West
Boral Concrete: Extensive Melbourne network with pump hire available
Holcim: Serves residential and commercial clients metro-wide
Minimum order: Most Melbourne suppliers require 1.0–3.0 m³ per delivery; short-load fees apply below minimums
Each pour type in the Melbourne concrete calculator uses a specific formula. Understanding these formulas helps you verify results and avoid costly over or under-ordering. For large Melbourne commercial pours, also consider our allowable bearing pressure calculator for foundation design checks.
Example — Melbourne backyard slab: 7m × 5m at 100mm thick
Example — Melbourne double-storey footing: 24m run, 500mm wide × 450mm deep
Example — Melbourne verandah piers: 6 posts, 300mm dia, 1.2m deep
Ready-mix concrete prices in Melbourne vary by grade, volume, and suburb. The table below reflects typical 2026 Melbourne market rates for budgeting. Delivery charges, pump hire, and short-load fees are additional. Request formal quotes from at least two Melbourne suppliers before ordering.
| Concrete Grade | Ready-Mix (per m³) | 20 kg Bags per m³ | Bag Price (Bunnings Melbourne) | Best For |
|---|---|---|---|---|
| 20 MPa | $185 – $220 | ~110 bags | $9.50 – $11.50 | Garden paths, pads, blinding |
| 25 MPa | $195 – $235 | ~110 bags | $10.50 – $12.50 | Residential slabs & driveways |
| 32 MPa | $215 – $260 | ~110 bags | $12.50 – $15.00 | Structural, coastal bayside suburbs |
| 40 MPa | $250 – $300 | ~110 bags | $15.00 – $18.00 | Commercial, CBD, industrial |
| Pump Hire | $450 – $900 per pour depending on boom reach — most Melbourne suppliers offer pump packages | |||
| Short Load Fee | $100 – $180 extra for loads under 3 m³ from most Melbourne metro batching plants | |||
All 2026 Melbourne concrete prices are indicative estimates for budgeting purposes only. Actual prices vary by supplier, suburb, delivery distance, volume ordered, and market conditions. Always obtain 2–3 formal quotes from licensed Melbourne concrete suppliers before placing any order.
Melbourne's four-seasons-in-one-day climate requires careful planning around concrete pours. Temperature swings, afternoon sea breezes, and the city's reactive clay soils all affect how concrete should be placed, finished, and cured for a long-lasting result.
Melbourne's summer temperatures can exceed 40°C, rapidly accelerating concrete setting and increasing the risk of plastic shrinkage cracking. Book early morning pours between October and March. Have wet hessian and plastic sheeting on-site ready to begin curing within 20–30 minutes of finishing. Avoid pouring between 11am and 3pm on days above 35°C. Request chilled mix water or ice from your Melbourne supplier if conditions are extreme.
Melbourne winters regularly see temperatures drop below 8°C overnight, slowing concrete hydration and strength gain. Protect fresh pours with insulating blankets when overnight temperatures are forecast below 5°C. Use accelerating admixtures in cold conditions and avoid pouring onto frozen or waterlogged sub-grade. In Melbourne's cooler months, allow an extra 20–30% curing time before loading or trafficking new slabs. Never pour on frost-affected ground.
Much of Melbourne is built on reactive basalt clay soils classified between Class M and Class H2 per AS 2870. Areas including Sunshine, Deer Park, Craigieburn, and Officer have highly reactive soils requiring engineer-designed raft or waffle pod slabs. Coastal bayside suburbs from Brighton to Frankston may have sandy soils requiring different sub-base preparation. Always obtain a soil report from a geotechnical engineer before designing any footing or slab system in the Melbourne metro area.
Victoria's NCC mandates a minimum F72 mesh for residential slabs in most Class M soil conditions. H1 and H2 reactive soil zones across Melbourne's growth corridors — Clyde, Tarneit, Mickleham — typically require F82 or F92 mesh and thickened edge beams. Driveways require SL72 mesh at mid-slab with 40mm cover. For double-storey homes or reactive Class H2 sites, always engage a structural engineer for an engineer-designed slab specification before ordering concrete.
Deciding between delivered ready-mix concrete and premix bags from a Melbourne hardware store depends on pour volume, site access, and time constraints. Both options are widely available across Melbourne's metro and suburban areas.
