Neither option wins every time. Pavers cope with moving ground and you can use them straight away; a concrete slab copes with heavy parked vehicles and big, plain areas. For most Darwin homes, it comes down to three things: how soft or wet your soil gets, whether you can live without the driveway for about a week, and where the water goes when a monsoon storm hits.
We'll give you an honest side-by-side here, because we're happy to build either one. We lay concrete driveways and we lay paved driveways.
Stiff slab or flexible paving?
This is the heart of it: the two surfaces fail in completely different ways. Concrete is one solid, rigid sheet. It's strong and has no gaps, but if the ground beneath shifts enough, it splits. Paving is made of hundreds of separate units. Each one is weaker on its own, yet as a whole they bend with the ground, taking up movement by nudging slightly out of place.
| What you're weighing up | Concrete slab | Segmental pavers |
|---|---|---|
| Upfront cost | Normally lower per square metre on large, simple drives | Higher, because laying by hand is slow |
| Ground movement | Rigid, so movement can show as cracks | Shifts and settles, which helps on unstable soil |
| Repairs | Patches stand out against older concrete | Lift the broken paver and drop in a new one |
| Using it again | About a week off it, kept moist while it cures | Ready once the joints are sanded and compacted |
| Heavy vehicles left parked | Better, since the load spreads across the slab | Workable with the right design, but less forgiving |
| Services underneath | Cut through the concrete, then patch | Lift, dig, then relay the same pavers |
| Joints to look after | Just the control joints | Joint sand needs topping up, and weeds can sprout |
Nearly every other difference between the two traces back to that rigid-versus-flexible split.
When we'd recommend concrete
With concrete you get one continuous surface, so there's no joint sand to replace, no weeds pushing up through gaps and no pavers dipping at different rates. It carries parked weight better too. The steel inside shares the load over the whole slab instead of pushing it into the bedding under one spot, which is handy if you keep a boat, caravan or work ute at home. On a large, regular shape it's usually the cheaper option per square metre, and you can dress it up with exposed aggregate, stamping or colour. A textured slab also holds traction well in a wet-season downpour, with no jointing sand for the rain to wash out. The trade-offs? You'll park on the street for about a week while it cures, repairs tend to show, and getting to anything buried underneath means cutting through it.
When we'd recommend pavers
Pavers move with the ground instead of cracking. On the clayey patches of Darwin soil that swell through the wet and shrink through the dry, that's a genuine advantage you'll notice over the years. You can drive on them as soon as the joints are finished, and replacing a damaged paver costs very little. Need a pipe or cable run under the drive later? We lift the pavers, dig the trench and lay them back down. On the downside, labour adds up on large areas, the joints need occasional care (heavy storms can scour out the sand, and our humidity suits moss and weeds), the edge restraints have to be built properly or the paving slowly spreads, and they're less tolerant of heavy vehicles parked for long periods.
Working out what suits your block
Run through these points with your own property in mind. Whichever way you go, lodge a request with Before You Dig Australia before any digging starts so underground services are marked.
- Moving ground: pavers flex and resettle, while a slab stays put until it cracks.
- Time off the drive: pavers can be used straight away; concrete needs roughly a week of moist curing in our heat.
- Repairs: a replaced paver is hard to spot, but patched concrete usually isn't.
- Heavy vehicles parked long-term: concrete spreads the load better.
- Large, simple shapes: concrete usually costs less.
- Appearance: pavers give you more shapes and laying patterns, while concrete gives you more finishes.
