What a slab costs, and why we put the price on screen.
Concreting is one of the most estimable trades there is: area in m², by the spec, by the finish. So instead of making you wait for a measure to learn a single number, we put an honest by-the-m² range on the screen first. Here is roughly where the numbers sit, what moves them, and how we keep our quote something you can actually compare.
An honest by-the-m² range, in under a minute.
Tell us what you are pouring, the m² and the finish, and see a real supplied-and-laid band. It is a guide range, not a quote: the free measure pins your exact number on site, and it never folds excavation, the crossover or the structural design into a round figure.
Price my slab
An honest by-the-m² range in under a minute, supplied and laid. Every job is quoted exactly on site after a free measure, not over the phone.
Your estimate appears here.
Step through the questions on the left. As soon as you answer the last one, we point you to the honest scope and a realistic range for a job your size.
Supplied and laid, by the m², 2026.
| Cheap quote (no thickness or mesh named, poured over fill) | $45 to $60/m² |
| Plain / broom finish (the grey workhorse, compacted base, control joints) | $65 to $95/m² |
| Exposed aggregate (decorative stone, washed back and sealed) | $100 to $150/m² |
| Coloured / stencil (colour or pattern, sealed, paver look without the joints) | $100 to $160/m² |
| Honed / decorative (ground, polished and sealed, the top of the range) | $130 to $200/m² |
Six things that decide where your quote lands.
Most of them are in the base, the reo and the finish you choose, not in the look of the finished surface. All of them decide what you pay, and how long the slab stays flat and crack-free.
The finish
The single biggest lever. Plain or broom finish sits at the bottom, then exposed aggregate, coloured or stencil, and honed or polished at the top. The finish is the surface and the sealing, and it is named on the quote, never left as just "concrete".
The area in m²
Cost is close to linear in area, so the size is the single biggest number on the quote. A small path and a full driveway are not the same job, which is why we price by the m² after a measure rather than off a photo.
Thickness, mesh and reo
The slab thickness and the mesh and reo, sized off the site classification, not a guess. A standard driveway is 100 mm with SL72 mesh, stepped up to 125 to 150 mm with SL82 or bars for reactive soil or heavier vehicles. This is the part a cheap quote quietly skimps.
Site prep and excavation
Excavation, the compacted base and any cut and fill are real costs and are itemised. Rock, spoil removal and imported fill can move the number, which is why we pin heavy excavation on the measure rather than fold it into a round figure.
Access for the truck or pump
Easy access for the concrete truck or the pump keeps the cost down. A long barrow run or a pump line to a tight backyard adds labour, and we cost it on the quote once we see the site, never spring it on you at the end.
The site classification and design
A structural house or shed slab is designed to AS 2870 off a soil test, which sets the thickness, the footings and the reo. The structural design and the registered paperwork cost a little more than a guessed slab, and they are what stop it moving.
Every concrete quote splits into the same lines.
So the figure you are comparing is tied to a finish, a thickness and a mesh you can read, not a single round number with nothing behind it.
- 1 Square metres and thickness. The price broken down by the m² and the slab thickness, 100 mm for a standard driveway, stepped up for reactive soil or vehicles. Not one round number for "a slab".
- 2 The site classification (AS 2870). The site classification, Class A through E, that the slab and footings are designed to. This is the line a cheap quote skips, and it is what decides whether the slab cracks or holds.
- 3 The mesh and reo. The mesh and reo named and sized, SL72 or SL82 and any bars, set to the soil classification or the loads the slab carries, never a one-size slab over loose fill.
- 4 The MPa and slump (AS 3600 / AS 1379). The concrete strength in MPa and the slump, ordered to AS 1379 and placed to AS 3600. "Concrete" with no strength named is the warning sign, not the number.
- 5 Base prep and vapour barrier. The excavation, the compacted base, and the vapour barrier under a habitable slab, each itemised, never a pour straight onto loose fill that lets damp through later.
- 6 The finish and sealing. The finish named, broom, exposed aggregate, coloured or honed, and the sealing on a decorative slab, so you know exactly what surface you are getting and what it costs.
- 7 Control joints and the guarantee. The control joints cut at the right spacing so it cracks on the line, and the 10-year guarantee on the slab and footings in writing, with the AS 2870 paperwork where the slab is structural.
What you get from us
- ✓Thickness and mesh named, sized to the soil
- ✓A properly compacted base under the slab
- ✓Control joints cut at the right spacing
- ✓A named concrete strength, 25 to 32 MPa
- ✓A vapour barrier under a habitable slab
- ✓10-year slab and footings guarantee in writing
Cowboy tells
- ✕"A standard slab." No thickness, no mesh
- ✕Poured straight over loose fill or grass
- ✕No joints, so it cracks across the middle
- ✕A watered-down mix that dusts and cracks
- ✕No vapour barrier, so damp comes through
- ✕Cash job, no guarantee in writing
A fixed, itemised quote. No surprises mid-pour.
Every quote lists exactly what you get, line by line, before you commit to anything.
- Measured by the m²The area measured on site, priced by the square metre, never estimated off a photo.
- Thickness, mesh and MPa namedThe slab thickness, the mesh and reo, and the concrete strength on the page, sized to the soil, never just "a slab".
- Base, finish and control jointsThe compacted base, the finish you chose, and the control joints, each itemised in writing.
- Excavation and a fixed priceExcavation and spoil removal as their own line, then a single price locked before the pour.
Anything outside this scope, a structural redesign, rock in the excavation, extra fill, is quoted separately, in writing, before it happens.
Fixed price
Locked before the pour
A path, a driveway, or the whole new-build package. We will tell you the smaller job if that is the honest answer.
A path, crossover or small pour
A path, a crossover to the road, a small pad or a set of steps, poured on a compacted base with control joints cut, set out to fall for drainage.
Wrong when: a full driveway, a shed slab or a structural house slab.
A driveway or shed slab
A full driveway or a shed or garage slab, the mesh and thickness sized to the soil, the finish named, on a properly compacted base. The job we do most.
Wrong when: just a path, or a fully structural new-build house slab.
A new-build slab, driveway and paths
The house slab, the driveway and the paths poured as one package on a new build, sequenced with the build, every finish and spec named on the one quote.
Wrong when: a single driveway or path on an existing home.
A structural house or shed slab
A structural slab engineered to AS 2870 off a site classification, with the footings, the reo and the vapour barrier to the design, and the VBA-registered paperwork.
Wrong when: a plain driveway or path with no structural design.
