Question 1

Do I need council approval for a concrete driveway in Adelaide?

Accepted Answer

In most cases, yes — particularly where the driveway crosses the footpath or kerb to connect to the road. This section is called the crossover and it's owned by your local council, which means any work on it requires a permit and must meet council specifications. The portion of the driveway within your own property line generally doesn't require approval, but check with your specific council before starting, as requirements vary. We handle the application process for many of our clients and can guide you through what's needed.

Question 2

How thick should a concrete driveway be in Adelaide?

Accepted Answer

For a standard residential driveway carrying passenger vehicles, 100mm (4 inches) of concrete with steel mesh reinforcement is the minimum we recommend. For driveways that will see heavier vehicles — caravans, boats, trailers, 4WDs, or work vehicles — we increase the thickness to 125–150mm with stronger reinforcement. Going thinner than 100mm is a false economy; cracks and failures become almost inevitable within a few years, especially given Adelaide's expansive clay soils and temperature swings.

Question 3

How much does a concrete driveway cost in Adelaide?

Accepted Answer

Costs vary based on size, finish, site access, and ground conditions. As a rough guide: plain concrete driveways start around $85–$120 per square metre, exposed aggregate sits around $130–$180 per square metre, and stamped or stencilled finishes typically run $150–$220 per square metre. Sites with poor access, sloping blocks, demolition of existing driveways, or extensive earthworks will add to that. We provide detailed itemised quotes so you know exactly what you're paying for.

Question 4

How long does it take to install a concrete driveway?

Accepted Answer

Most residential driveways are completed in 3–7 working days from start to finish, depending on size and complexity. The timeline typically breaks down as: 1 day for demolition and excavation, 1–2 days for formwork and reinforcement, 1 day for the pour and initial finishing, and 2–4 days of curing time before you can walk on it. Vehicles should stay off the concrete for a full 7 days minimum, ideally 14 days for heavier vehicles.

Question 5

Can I get a concrete driveway poured in winter in Adelaide?

Accepted Answer

Yes, Adelaide's mild winters are generally fine for concrete work, though we adjust our scheduling around weather forecasts. The two conditions we avoid are pouring during heavy rain (which damages the surface finish) and pouring when overnight temperatures are forecast below 5°C (which slows curing significantly). Summer pours can also be challenging in extreme heat — we often schedule early morning starts during heatwaves to give the concrete the best curing conditions.

Question 6

What's the best finish for a concrete driveway in Adelaide?

Accepted Answer

Exposed aggregate is consistently the most popular choice for Adelaide driveways — it's slip-resistant, hides stains well, handles heat and UV beautifully, and looks premium. Stamped and stencilled concrete are also excellent for homeowners wanting a paver or stone look, while plain broom finish remains a budget-friendly classic. We help every client choose a finish based on their home's style, the driveway's slope, and how much they want to invest.

Question 7

Will my concrete driveway crack?

Accepted Answer

All concrete cracks to some degree — it's the nature of the material as it cures and responds to ground movement, temperature, and load. The goal isn't to prevent cracks entirely; it's to control where they happen. We use proper steel mesh reinforcement, correctly placed control joints, and quality concrete mixes to keep cracking minimal and controlled. Driveways poured without proper reinforcement and joint planning are where you see ugly random cracking within a year or two.

Question 8

Do I need to seal my concrete driveway?

Accepted Answer

Sealing isn't strictly required, but it's strongly recommended — particularly for decorative finishes like exposed aggregate, stamped, or coloured concrete. A quality sealer protects against oil stains, UV fade, tyre marks, moss growth, and the absorption of moisture into the slab. We seal every driveway as part of the project and recommend resealing every 3–5 years to maintain protection.

Question 9

Can you pour a new concrete driveway over my existing one?

Accepted Answer

Sometimes, but usually not. Pouring fresh concrete directly over an old driveway rarely produces a good result — the new slab can't bond properly to the old one, control joints won't align, and any existing cracks or movement will telegraph through to the new surface within months. A much better option for tired old driveways is concrete resurfacing or spraycrete overlay, which is specifically designed to bond to existing concrete. Otherwise, full removal and replacement is the right answer.

Question 10

What's the maximum slope for a concrete driveway in Adelaide?

Accepted Answer

Adelaide councils generally allow driveway gradients up to 25% (1 in 4), though anything steeper than 15% (1 in 6) becomes uncomfortable for low-clearance vehicles. For steep driveways, we recommend a textured or exposed aggregate finish for traction, especially in wet conditions. If your block is particularly sloped, we can design transitions, retaining walls, or stepped sections to make the driveway functional and safe.
