Title: How Much Does a Concrete Driveway Cost in Adelaide? (2026 Guide)

---

If you've been quoted anywhere between $4,000 and $18,000 for a concrete driveway in Adelaide, you're not being misled — that range is real. The price depends on size, finish, site conditions, and whether your contractor is doing the work themselves or sending a subcontractor.

This guide breaks down exactly what you'll pay in 2026, what drives the cost up or down, and how to spot a quote that's too cheap to be genuine.

Quick Price Reference

Finish	Installed Price per m²
Plain grey broom finish	$65–$90/m²

Honed concrete	$100–$160/m²

Prices include concrete supply, labour, formwork, and basic ground prep. Excavation, tree root removal, and retaining walls are quoted separately.

Average Driveway Sizes and Total Costs

The most common residential driveway sizes in Adelaide metro:

Driveway Size	Area (approx)	Broom Finish	Exposed Aggregate
Single car (single garage)	20–30 m²	$1,300–$2,700	$1,800–$4,500
Double car (double garage)	40–55 m²	$2,600–$4,950	$3,600–$8,250
Long single (double-length)	50–70 m²	$3,250–$6,300	$4,500–$10,500
Double car + turning bay	70–100 m²	$4,550–$9,000	$6,300–$15,000

These are installed prices — material, labour, formwork, standard cut joints, and a clean finish. What's not included: Council permits (if required), tree root removal, retaining walls, drainage works.

What Drives the Cost Up

1. Finish type

Plain broom finish is the cheapest. Exposed aggregate costs 20–40% more because it requires a higher-grade concrete mix, careful washing at the right cure stage, and more labour per square metre. Honed concrete is the most labour-intensive — it's ground back smooth after curing, which adds time and tooling costs.

2. Site preparation

If your driveway site is at ground level with no existing concrete to remove, prep costs are minimal. But if you need to:

• Remove existing concrete or pavers (+$30–$60/m²)
• Excavate and cut levels (+$20–$50/m²)
• Remove tree roots or stumps (+$300–$1,200 depending on size)
• Install drainage or ag-pipe (+$40–$80/m²)

…the per-square-metre price climbs fast.

3. Soil conditions

This is the one most Adelaide homeowners don't expect. SA has significant reactive clay soils, particularly in the northern suburbs (Salisbury, Elizabeth, Para Hills, Gawler) and southern suburbs (Morphett Vale, Reynella). Reactive clay expands and contracts with moisture, which can crack a driveway poured without proper reinforcement.

On reactive soils (Class M, H1, or H2 under AS 2870), a good contractor will:

• Increase slab thickness (100mm → 125mm or 150mm)
• Use F72 mesh or fibre reinforcement
• Install a thicker sand or FCR base

That adds cost — but it's the difference between a driveway that lasts 20 years and one that cracks in five.

4. Access and truck pour logistics

Concrete is pumped or poured directly from the truck. If the site has restricted access — a narrow side gate, a long carry, or overhead power lines — a concrete pump is required (+$500–$900). Some inner-Adelaide properties with no rear lane access always require pumping.

5. Kerb cuts (footpath opening)

If your new driveway needs a new or widened kerb cut, you'll need Council approval and a licensed contractor to cut the kerb. This typically costs $400–$900 and requires a DA or minor works permit in most Adelaide councils.

---

What Keeps the Cost Down

• Broom finish: Standard, durable, and the most budget-friendly option. Still looks great when done well.
• Flat site, easy access: Minimal prep and no pump required.
• Getting 2–3 quotes from owner-operator businesses: You pay for the actual crew doing the work, not a margin on top of a subcontractor.
• Scheduling flexibility: If you can book mid-week or during a quieter period (winter months in SA), some contractors offer better pricing.

Red Flags in a Cheap Quote

If a quote comes in 30% below every other price, ask:

• Is GST included? (All quotes should be GST-inclusive)
• What thickness of concrete? (100mm is minimum; 125mm for a vehicle surface on reactive soil)
• Is reinforcement included? (Mesh or fibre — not optional on clay soils)
• Will you be pouring yourself or using a subcontractor?
• Is the quote fixed price or hourly?

Cheap quotes often come from operators who cut corners on thickness, skip reinforcement, or use a lower-grade concrete mix (20 MPa instead of 25 MPa). You won't notice until 3–5 years later when the cracks appear.

How Adelaide Suburbs Affect Your Price

Your location affects cost in two ways: soil conditions (explained above) and travel/logistics.

Suburb Zone	Soil Class (typical)	Notes
Salisbury, Elizabeth, Gawler	H1/H2 reactive	Heavier reinforcement required
Para Hills, Ingle Farm, Davoren Park	H1 reactive	Extra prep recommended
Modbury, Tea Tree Gully, Campbelltown	Class M	Standard reinforcement
Mitcham, Unley, Norwood	Class M	Standard reinforcement
Morphett Vale, Hallett Cove, Reynella	H1 reactive	Heavier reinforcement required
Glenelg, Henley Beach, Semaphore	Class A–S	Minimal reactive risk
Port Adelaide, Woodville, Findon	Class S	Standard to moderate
Windsor Gardens, Prospect, Croydon Park	Class M	Standard reinforcement

If you're in a reactive clay area and your quote doesn't mention soil class, thickening, or reinforcement — ask about it.

Is a Concrete Driveway Worth It vs Pavers?

We're often asked whether concrete or pavers is better value. Here's the honest comparison:

Factor	Concrete	Pavers
Installed cost	$65–$150/m²	$100–$200/m²
Lifespan	25–40 years	20–30 years (with resets)
Maintenance	Seal every 5–8 years	Weed, reset, re-sand periodically
Crack risk	Low–medium (with good install)	Individual pavers can be replaced
Appearance options	Exposed, coloured, honed, broom	Many patterns and colours
Council permits	Usually no (driveway only)	Usually no

For most Adelaide homes, concrete offers better value per year of lifespan, especially when exposed aggregate is chosen — it's decorative, durable, and low maintenance.

Frequently Asked Questions

How long does a concrete driveway take to cure?

Concrete reaches initial set within 24–48 hours — enough to walk on. But full strength (28-day cure) takes about a month. We recommend keeping vehicles off for at least 7 days and avoiding heavy vehicles for 28 days.

Do I need a Council permit for a concrete driveway in Adelaide?

For most standard driveways replacing an existing one, no permit is required. If you're creating a new crossover (kerb cut), you'll need approval from your local council. We can advise on this during the free site visit.

What concrete mix do you use for driveways?

We use 25 MPa concrete as standard, with 32 MPa available for heavy-vehicle areas. All driveways include F72 steel mesh reinforcement. On reactive clay soils, we increase slab thickness and may recommend fibre reinforcement as well.

Can I get exposed aggregate on a sloped driveway?

Yes — exposed aggregate works well on slopes. We adjust the mix slightly and use a retarder spray to ensure consistent washing depth across the surface. Slopes also need careful joint placement to manage water runoff.
