Exposed Aggregate & Decorative Driveways in Melton
Exposed aggregate is the most popular driveway finish in Melton's newer estates. There is one rule worth knowing before you plan it: it stops at your property boundary.
The rule nobody tells you until it is too late
You can have a decorative driveway. You cannot have a decorative crossover.
Melton City Council's standard drawing MCC 501 states it directly: **no pattern-paved finish or coloured concrete is to be used**. The Crossover Policy adds that where a footpath is present, or likely to be constructed in future, crossovers must be **plain concrete or match the existing footpath**, and that a crossover should be generally consistent with neighbourhood character.
So the arrangement that works, and the one you see across Melton's newer estates, is decorative concrete up to the property boundary and plain concrete across the crossover to the kerb.
Done carelessly that looks like a mistake. Done deliberately — with the transition falling on the boundary line, joints set out to suit and the plain section detailed properly — it reads as a considered edge rather than a compromise. We plan that junction as part of the design rather than discovering it on pour day.
The finishes
**Exposed aggregate.** The cement paste at the surface is washed back to reveal the stone in the mix. The look depends entirely on the aggregate chosen, so the choice of stone is the design decision, not an afterthought. Naturally slip resistant thanks to the exposed stone texture, and it hides dirt and tyre marks better than plain concrete — which matters on a driveway.
**Coloured concrete.** Oxide through the mix rather than on the surface, so the colour runs full depth and does not wear off. Best kept to muted, earthy tones — strong colours date quickly and are unforgiving of any patch repair.
**Honed concrete.** The surface is ground back to expose the aggregate and then polished to a smooth, refined finish. The most premium look of the three, and the most expensive. Because grinding makes the surface smoother, slip resistance deserves real attention where the driveway slopes or gets wet.
**Plain with feature banding.** Often the smartest value: a plain slab with exposed aggregate or contrasting bands set into the joint lines. A fraction of the cost of a fully decorative drive with much of the visual effect.
Slip resistance is not optional
Council requires finished surfaces on the crossover to comply with **AS 4586**, the slip resistance classification standard for new pedestrian surface materials. That applies to the crossover, but the same thinking should guide what you choose for the driveway.
A driveway is walked on in the rain, at night, by people carrying shopping. Honed finishes look superb and are the slipperiest of the options; exposed aggregate is the most naturally grippy. If your driveway has any real slope — and plenty in Melton's newer estates do — that should weigh in the decision.
What it costs, and why
We quote on site. What moves the number:
- **Which finish** — plain is the baseline, exposed aggregate a step up, coloured a further step, honed the most expensive because of the grinding and polishing labour - **The aggregate itself**, which varies substantially in price by stone type - **Area and complexity**, since curves, returns and multiple levels cost more per square metre than a simple rectangle - **Base and excavation**, which on reactive clay is not the place to save money - **Whether the crossover is included**, bringing council approval, consent and inspection into scope - **Removal of an existing driveway**
Ask any competing quote what it has allowed for the base and reinforcement, not just the finish. A beautiful surface on an inadequate base is a short-lived driveway, and it is where corners get cut invisibly.
Looking after it
Decorative concrete rewards a little maintenance. Sealing helps it resist staining and keeps colour looking fresh, and it needs redoing periodically. Oil drips lift more easily from a sealed surface. Avoid harsh acid cleaners, which can etch the surface and dull colour.
One honest caveat: any concrete can crack, decorative included, and a crack is more visible in a decorative finish than in plain broom. Proper base preparation, correct reinforcement and well-placed control joints are what keep that to a hairline — which is why the base matters more than the brochure.
Why choose us for exposed aggregate & decorative finishes
- Boundary transition designed in, so the plain crossover looks deliberate
- Aggregate selected as a design decision, not left to the supplier
- Slip resistance weighed properly on sloping driveways
- Base and reinforcement quoted explicitly, not hidden under the finish
- Feature banding offered where it gets the look for less
Exposed Aggregate & Decorative Finishes — common questions
Can I have exposed aggregate on my crossover?
No. Melton's standard drawing MCC 501 states no pattern-paved finish or coloured concrete is to be used on the crossover, and the policy requires plain concrete — or concrete matching the existing footpath — where a footpath exists or is likely later. Decorative finishes are for the driveway inside your property boundary. The standard arrangement is decorative to the boundary, plain across the crossover, with the transition designed to fall on the boundary line.
What is the difference between exposed aggregate and honed concrete?
Exposed aggregate is washed back while curing so the stone in the mix shows through, giving a textured, naturally slip-resistant surface. Honed concrete is ground back after curing and polished smooth, exposing the aggregate in a refined, flatter finish. Honed is the more premium look and the more expensive because of the grinding labour — and being smoother, it needs more thought about slip resistance on a sloping drive.
How much more does exposed aggregate cost than plain concrete?
It is a genuine step up, and honed more again, but the spread depends heavily on the aggregate you choose — stone types vary substantially in price — as well as area, complexity and base requirements. We quote on site rather than by the square metre. If budget is the constraint, plain concrete with exposed aggregate feature banding gets much of the look for a fraction of the cost.
Does exposed aggregate get slippery?
It is the most naturally slip-resistant of the decorative finishes, because the exposed stone gives the surface texture. Honed concrete is the slipperiest, being ground smooth. Council requires crossover surfaces to comply with AS 4586 for slip resistance, and the same thinking is worth applying to your driveway — particularly if it slopes, which many Melton estate driveways do.
Will coloured concrete fade?
Oxide colour is mixed through the concrete rather than applied to the surface, so it runs full depth and does not wear off with traffic. Some softening of tone with sun exposure over years is normal, and sealing helps keep it looking fresh. The bigger risk is choosing a strong colour that dates, or that makes any future patch repair obvious — muted, earthy tones age much better.
Does decorative concrete need sealing?
It benefits from it. Sealing helps resist staining, keeps colour looking fresh and makes oil drips much easier to lift. It needs redoing periodically rather than being a one-off. Avoid harsh acid-based cleaners, which can etch the surface and dull the colour. We will tell you what your particular finish wants and roughly how often.
Will my decorative driveway crack?
Any concrete can crack — it shrinks as it cures, so the aim is controlling where rather than preventing it entirely. The honest caveat with decorative work is that a crack shows more against exposed aggregate or colour than against plain broom finish. Proper base compaction, correct reinforcement placement and well-set-out control joints are what keep it to a hairline, which is exactly why the base matters more than the surface.
Can you match the decorative driveway to my house?
Usually yes — aggregate selection and oxide colour give a lot of latitude, and it is worth choosing against your brickwork, render or roof rather than from a sample in isolation. Bring us the house colours and we will bring samples to site, since concrete reads very differently outdoors in daylight than it does under shed lighting. Note that whatever you choose, the crossover section still has to be plain.
