Most concrete driveways end up with one of four surfaces: broomed, exposed aggregate, coloured or stamped. They differ in price, in how they feel underfoot and in how they wear over time, but the slab underneath is the same. The finish is only the top few millimetres. Your driveway's lifespan is decided by the base, the reinforcement and the curing.
Below we compare all four and look at how each one handles life in Darwin: heavy wet-season rain, water running across flat driveways, the muggy build-up and that intense sun.
All four finishes side by side
In day-to-day terms, the real differences are cost, grip and how much looking after each one needs.
| Finish | Look | Cost | Grip when wet | Maintenance |
|---|---|---|---|---|
| Broom | Plain, practical grey | Lowest | Good | Minimal |
| Exposed aggregate | Natural stone texture | Middle to higher | Excellent | Reseal every few years |
| Coloured | Tinted to suit your home | A little more | Depends on the texture underneath | Sealer protects the colour |
| Stamped | Slate, stone or paver patterns | Highest | Depends on the sealer | Ongoing resealing |
In short, the further down the table you go, the more eye-catching the result and the more maintenance you take on.
Broom finish
Before the concrete hardens, we pull a stiff broom over the surface to leave fine ridges. It's the most common driveway finish in Australia and, for most homes, the sensible starting point. It's the cheapest, it stays grippy when wet and it hides dirt reasonably well. Run the ridges across the slope rather than along it and it'll handle a Darwin downpour without fuss.
- Cost: the lowest of the four, thanks to a standard mix and quick finishing.
- Grip: reliable in the wet, and best when the ridges run across the fall.
- Appearance: neat and practical, not a showpiece.
Exposed aggregate
While the concrete is still green, we wash away the surface layer of cement paste so the stones in the mix show through. The result is a textured, attractive surface with excellent grip. It's the decorative finish we pour most often across Darwin, and people pick it for safety just as much as looks. You'll find examples on our exposed aggregate page.
- Grip: the stones hold tyres much better than a smooth surface, even on a shady drive that stays damp and mossy all wet season.
- Hides wear: tyre marks, leaf stains and everyday weathering disappear into the texture.
- Cost: more than broom, and worth it on a shaded or regularly wet driveway.
Coloured concrete
We either add oxide pigment to the mix or work a colour hardener into the surface while finishing, and there's a wide range of shades. Colour doesn't change the texture, so you can pair it with any of the other three finishes. Before you commit, it's worth asking yourself a few things:
- Are you happy to keep it sealed? Our tropical sun fades unsealed colour faster than most people expect.
- How visible is it? A driveway out the front deserves more than a side track down to the shed.
- What's the priority? The base and reinforcement always come before the finish.
Stamped concrete
We press textured mats into the wet surface so it looks like slate, flagstone, brick or timber. You get the most control over the look, and it costs the most, both in materials and in the skilled labour needed to stamp the whole area before it goes off. In Darwin's heat that window can be tight, particularly on a hot, windy day, so we usually start decorative pours at dawn. Our stamped concrete service has more detail.
- Sealer: both appearance and slip resistance depend on it, so make sure anti-slip grit is added.
- Choosing a pattern: a deeply textured stamp holds better in the wet than a flat slate design.
- Maintenance: plan for regular resealing from day one.
Choosing a finish for your block
Start with your property, not the sample board. On a Darwin driveway, particularly one that stays wet through the monsoon, grip matters most and appearance comes second.
- How does water move across it? If storm runoff flows over the drive, put more weight on grip.
- Is it shaded? Drives under mango trees or tall palms stay damp through the wet and go green, so aggregate or broom is the safer bet.
- How much sun does it get? Darker colours get hot underfoot and fade quicker under high UV.
- Keep the wheel paths grippy: on a damp drive, use decorative finishes along the edges instead.
- Look at colours next to your house: shades look different in real light, so view samples on site.
Combining finishes
On a large driveway, two finishes often look better than one, and you get to spend where guests will see it. We'll agree on the layout before the pour, because the joins have to be planned in advance.
- Exposed aggregate with a coloured border: good grip where the wheels run and a clean, defined edge.
- Broomed driveway with a stamped entrance: keeps most of the area affordable and adds a feature at the front.
- Coloured exposed aggregate: pigment through the mix with the stone showing on top.
- Different finishes for the drive and the path: a walkway can be smoother than where cars drive.
Need help choosing?
The right finish depends on your drainage, how much shade, rain and sun the drive gets, and how much maintenance you're willing to do. Tell us about your place and we'll recommend a finish that puts safe footing first, then bring samples so you can see them in your own light.
