Concrete Driveways near you

Queensland's guide sets the requirement plainly: the ground clearance for driveways and the like shall be in accordance with AS/NZS 2890.1 Parking Facilities, Off-Street Parking, Appendix C, with the template car being the B85 for domestic properties. Appendix C is the check that a car can traverse changes of grade without grounding on its front overhang, rear overhang or belly.

That check matters at three places on a typical Australian driveway: at the kerb crossing, where the road-level grade meets the driveway; at any crest partway up a steep block; and at the transition into the garage, where a falling driveway has to flatten out before the roller door. Steep blocks in Sydney, Brisbane and hilly parts of Melbourne and Hobart make this a real and frequent problem, and the fix is transition zones of intermediate grade rather than a single change of slope.

It is worth asking a contractor directly whether they have checked the profile against the template, and worth asking before the formwork goes in rather than after. Once the concrete is poured, correcting a grounding point means cutting out and re-pouring a section, and the new section will never match the old one in colour. This is the single most expensive mistake available on a driveway.

The subgrade is prepared and compacted, a base course is placed and compacted, and only then is the reinforcement set and the concrete poured. The QBCC's own article on driveways and paths identifies soft or uneven foundations as reducing path performance, and it identifies a specific failure worth watching for: mesh dropping to the bottom of the slab instead of maintaining proper cover, which leaves the reinforcement in the wrong place to do its job.

Reinforcement position is one of those things you can only verify on the day. Bar chairs hold the mesh at the right height, and someone walking across the mesh during the pour can push it down. If you are around when the concrete goes in, that is the thing to look at. A driveway with its mesh sitting on the ground is a driveway with no useful reinforcement at all.

Joints come next, and the same QBCC article names missing isolation joints at walls and other rigid structures as allowing movement to transfer into the concrete. Contraction joints control where shrinkage cracks appear, isolation joints separate the driveway from the house, the garage slab, a retaining wall or a service pit, and both must be placed before the pour is planned rather than sawn as an afterthought. Queensland's tolerances guide reinforces the point: cracking where the builder did not make allowance for shrinkage or general movement — isolation joints around penetrations such as verandah posts and pipes, expansion joints, control joints and contraction joints — is assessed against the acceptance criteria and is defective where the limits are exceeded.

The part of your driveway between the property boundary and the road is not yours, and the council controls it. That crossing is dealt with in the driveway repair guide, and the short version is to settle it with the council before you commit to a pour, because the levels at the boundary are usually fixed by the council's crossing detail and everything up the driveway has to work back from them.

On the property side, whether a development approval is needed depends on the state, the council and the site — sloping sites, heritage areas, bushfire and flood overlays and rules capping the hard paved area of a lot all change the answer. The one that catches people most often is the impervious area cap, because a driveway is usually the largest single area of new hard surface on a residential block.

Licensing is a state matter. Queensland's QBCC has a concreting licence class whose published scope is concreting including installing formwork, reinforcement and concrete, with incidental work of another class allowed under a small value cap. New South Wales offers a licence check through Service NSW covering residential building work and the occupational trades. In every state, ask for the number, check it yourself and confirm public liability cover, because a driveway pour involves a truck, a pump and a lot of traffic across a footpath.

A driveway is the only surface on a block asked to carry a car and to be walked on, and in a new house it is the second job that is regulated. Our concrete walkways guide covers the step-free path rule itself; what lands on the driveway is the thing at the end of that path — the parking space, which the ABCB Livable Housing Design Standard gives dimensions and a maximum fall.

Where a car parking space is connected to or forms part of that required access path, the standard requires at least one space with a minimum unobstructed area of 3200 mm wide by 5400 mm long, and a gradient not more than 1:33 for bitumen or 1:40 for any other surface material. For concrete, that is 1:40 — a very flat parking space, and a genuine design constraint on a sloping block.

Even on an existing house that is not covered by the standard, those numbers are a useful sanity check. A parking area falling more steeply than about 1:40 is uncomfortable to stand a trolley, a pram or a wheelchair on, and a driveway that will be walked down as often as it is driven down is worth designing with that in mind rather than purely for the car.

Ask every quote for the same seven things: the subgrade and base preparation, the slab thickness, the reinforcement type and how it will be held at the right height, the joint layout drawn on a sketch, the falls and where the water goes, the finish and whether it is sealed, and confirmation that the profile has been checked for ground clearance against AS/NZS 2890.1 Appendix C using the B85 template car. Quotes that differ wildly on price usually differ on the first three.

Curing is the item most often dropped and the one that decides surface durability. Ask how the slab will be cured and for how long, and ask when a vehicle can be driven on it. Then keep to it. Queensland's guide sets an acceptance criterion of 15 mm for variation between the actual surface profile and the design profile, and 5 mm of stepping between adjacent paving elements, but none of those numbers help a surface that dried out in its first week.

The Australian Consumer Law guarantees apply — acceptable care and skill, fitness for any stated purpose, supply within a reasonable time — and Queensland's guide gives a longer view for safety-related defects, treating cracking in driveways and paving assessed against the acceptance criteria as defective for six years and six months from completion where it constitutes a health and safety issue such as a trip hazard or renders the paving structurally unsound.
