Concrete Slab Cost per Square Metre and per Cubic Metre in Melbourne
The cost of a slab can be calculated on a per square metre (m2) or per cubic metre (m3) basis. Understanding the distinction helps homeowners and builders budget accurately:
- Concrete slab cost per m2 reflects the surface area to be covered, incorporating thickness and finishing.
- Concrete slab cost per m3 accounts for volume—thickness multiplied by area—and is vital when ordering materials.
| Slab Thickness | Cost per m2 (AUD) | Cost per m3 (AUD) | Typical Applications |
|---|---|---|---|
| 75 mm (0.075m) | 90 – 110 | 1200 – 1400 | Lightweight garden slabs, small sheds |
| 100 mm (0.1m) | 110 – 140 | 1100 – 1300 | Garage slabs, general purpose pads |
| 150 mm (0.15m) | 150 – 190 | 1000 – 1200 | Structural slabs, pillars |
The cost variability by slab thickness and grade is a key factor. Thicker slabs use more cement, aggregate, and reinforcement, raising the material cost per square metre but often lowering per cubic metre costs due to economies of scale. Additionally, slab grade specifying desired compressive strength (e.g., 20 MPa vs 32 MPa) influences material selection and price.
When comparing regional pricing adjustments for Melbourne vs other Australian cities, Melbourne slab costs sit towards the mid to higher range due to urban demand and labour rates, surpassing many regional centres but generally lower than Sydney’s peak market. For precise budgeting, understanding how many bags of concrete per cubic metre are required is fundamental, as detailed in our guide on calculating bags of concrete per cubic metre.
These sizing and cost metrics provide a robust framework for projecting Melbourne slab expenses.
Specific Slab Use Cases and Their Cost Implications
Different slab applications incur varying costs — knowing this helps tailor budgets to project scope. Here’s a detailed look at common Melbourne slab types:
Garden Shed Concrete Slab Cost and Size Considerations
Sheds usually require slabs between 75mm and 100mm thick, with minimal reinforcement unless housing heavy equipment. The garden shed concrete slab cost per m2 in Melbourne’s northern suburbs averages AUD 90-130. A smaller 3 x 3 m shed slab might cost around AUD 900 to 1,170 in total. Factors such as slab finish and local soil bearing capacity influence these figures.

Concrete Pad for Garage — Cost Factors and Typical Estimates
Garage slabs require heavier duty construction with thicker concrete (100mm to 150mm) and steel mesh or rebar reinforcement to accommodate vehicle loads. Melbourne concrete slab for garage costs range from AUD 110 to 160 per m2. A typical double garage pad (6 x 6 m) can cost between AUD 3,960 and 5,760.
Load capacity, access for machinery, and concrete finish types (e.g., broom finish vs smooth) further differentiate pricing.
Slab Cost Pillar — Specialized Pricing for Structural Supports
Slab cost pillar pricing refers to slabs designed for vertical structural supports, where higher strength concrete, increased thickness, and specialized formwork escalate costs. These slabs often exceed AUD 180 per m2 in Melbourne. Labour-intensive formwork and reinforcement installation add to the labour component.
These costs require accounting for specialised expertise and sometimes permits that add to the total building slab cost. Beyond standard slabs, this category accounts for critical structural integrity in residential and commercial builds.
While structural slab costs are crucial, concrete slabs in decorative applications like coloured driveways offer a contrasting cost and aesthetic perspective.
