Concreting FAQs

As a rule of thumb, you can walk on new concrete after 24–48 hours and drive a normal car onto a residential driveway after about 7 days. Heavy vehicles should wait around 28 days, which is when concrete reaches most of its design strength. These are guides — we give you exact timings for your specific pour, weather and mix.

Concrete doesn't simply "dry" — it cures through a chemical reaction (hydration) that keeps hardening for weeks. The surface firms up within hours, it's walkable in 1–2 days, and it reaches roughly 70% of strength in about 7 days and near full strength at 28 days. Keeping it moist in the first days actually makes it stronger, not weaker.

A standard residential concrete driveway for cars is generally 100mm (4 inches) thick over a well-prepared base, with steel mesh reinforcement. Where heavier vehicles, trucks, caravans or boats will use it, 125–150mm is common. The right thickness depends on the ground and the loads — we set it out to suit your site.

Plain concrete doesn't have to be sealed to function, but sealing is strongly recommended for driveways and decorative finishes. A good sealer resists oil and stains, reduces surface dusting, helps colour and exposed aggregate last, and makes the surface much easier to clean. Decorative, coloured and exposed aggregate concrete in particular benefits from sealing.

As a general guide, reseal exposed aggregate and decorative concrete every 2–4 years, and plain sealed concrete every 3–5 years, depending on wear, sun exposure and traffic. Driveways in full sun or heavy use need it more often. It's a low-cost job that noticeably extends the life and looks of your concrete.

The concrete driveway on your own property usually doesn't need approval, but the crossover — the section from the road to your property boundary — is council-controlled and typically requires a permit from the City of Mount Gambier or the relevant district council (such as Grant, Wattle Range or Naracoorte Lucindale). We can talk you through the crossover process and work in with council requirements.

Concrete cracks mainly from shrinkage as it cures, ground movement, poor base preparation, or missing/late control joints. It can't be guaranteed 100% crack-free, but the risk is dramatically reduced with proper base compaction, correct thickness and reinforcement, control joints cut in the right places and spacing, and good curing. That preparation is exactly where we focus.

It depends on the job — size, thickness, finish, site prep and access all affect the price. Plain concrete is the most affordable, with exposed aggregate, coloured, stamped and polished finishes costing more. Rather than a vague ballpark, we give you a written fixed-price quote for your specific job. Our cost guides explain the typical per-square-metre ranges.

A properly prepared and poured concrete driveway can last 30–50 years or more with minimal maintenance. Sealing it and keeping the drainage clear helps it reach the top of that range. Good preparation is the single biggest factor in how long concrete lasts.

Yes — concrete is poured year-round on the Limestone Coast, but weather matters. We avoid pouring in heavy rain or frost and plan around the forecast, because pouring conditions and curing conditions affect the final result. We'll always give you honest advice on timing rather than rushing a pour in the wrong weather.

Yes. Where you're replacing an existing driveway, path or slab, we can break out and remove the old concrete, prepare the base, and pour the new surface. Removal and cartage is included in your quote so there are no surprises.

Absolutely. Alongside residential driveways and slabs, we do rural work across the Limestone Coast — shed floors, machinery slabs, footings, cattle yards, dairy and farm concreting, plus commercial floors, car parks and concrete pumping.
