How Much Does a Concrete Slab Cost in Brisbane? (2025 Guide)
If you’re planning a new driveway, patio, or shed base, one of the first questions you’ll ask is how much does a concrete slab cost? In Brisbane, a standard concrete slab costs between $90 and $150 per square metre, depending on slab thickness, MPA strength, finish type, and site access. For most homes, the average spend ranges from $3,000 to $7,000, with decorative finishes like polished or exposed aggregate concrete on the higher end.
While it may be tempting to pour a slab yourself, concreting requires knowledge of soil conditions, reinforcement, drainage, and curing times. Mistakes can lead to cracking, uneven surfaces, and costly repairs. That’s why many Brisbane homeowners choose to hire local experts like West Brisbane Landscaping’s Concreting Services for durable, professional finishes.
Cost of Concrete Per Square Metre in Brisbane
So, how much does a concrete slab cost per square metre? On average, plain concrete costs $90 – $120 per m², coloured slabs fall around $100 – $130 per m², polished slabs typically run $120 – $150 per m², and exposed aggregate concrete ranges from $120 – $180 per m².
Here’s a quick breakdown:
Plain concrete: Budget-friendly, durable, starting at $90/m²
Coloured concrete: Adds style without breaking the bank
Polished concrete: Sleek and long-lasting, ideal for patios
Exposed aggregate concrete: Premium finish, excellent for driveways
This is why when people ask “how much is concrete per square metre” or “how much does concrete cost per square metre,” the answer depends heavily on the finish chosen.
What Does MPA Mean in Concrete Pricing?
Another factor influencing how much a concrete slab costs is MPA strength. MPA (megapascals) measures compressive strength. A 20 MPA mix might be used for garden paths, while 25 – 32 MPA is typical for driveways and heavy load areas. Higher MPA means higher cost per cubic metre, but also greater durability.
For example:
20 MPA concrete: $200 – $220 per m³ (light duty)
25 MPA concrete: $220 – $250 per m³ (standard residential)
32 MPA+ concrete: $250+ per m³ (heavy vehicles, commercial use)
Understanding MPA helps you compare quotes. At West Brisbane Landscaping, we guide clients through these choices, ensuring the slab matches the project’s needs. Whether that’s a driveway, shed, or retaining wall base.
How Much Does It Cost to Concrete a Driveway?
One of the most common homeowner questions is how much does it cost to concrete a driveway? In Brisbane, expect to pay between $3,000 and $7,000 depending on size, access, and finish. A single-car driveway might cost $3,000 – $4,000, while a double driveway with exposed aggregate could be closer to $6,000 – $7,000.
Factors that affect driveway costs:
Size and thickness (100mm vs 150mm slabs)
Reinforcement type (mesh, rebar)
Site excavation and earthmoving needs
Finish type (plain vs exposed aggregate)
Driveways are a long-term investment, and a well laid slab can last over 30 years with minimal maintenance.
How Much Is Exposed Aggregate Concrete?
Many Brisbane homeowners upgrade to exposed aggregate. So, how much is exposed aggregate concrete? On average, $120 – $180 per m². While this is more expensive than plain concrete, exposed aggregate adds visual appeal, better slip resistance, and long term durability.
Clients often choose it for high traffic areas like driveways, patios, and pool surrounds. Recently, we completed an exposed aggregate driveway in Kenmore, The client invested more upfront but added significant street appeal to their property.
How Much Does Polished Concrete Cost?
Another variation people ask about is how much does polished concrete cost? Polished concrete runs about $120 – $150 per m². It requires grinding, sealing, and polishing but offers a modern finish perfect for indoor outdoor living areas.
Compared to tiles or pavers, polished concrete is often more durable and easier to maintain. For large entertainment areas, polished slabs give a seamless, stylish look. See our Paving & Tiling Services for related solutions.
