Home › Guides › Concrete vs Pavers
Whether pavers or poured concrete suit your Townsville driveway comes down to the ground you are on. On the reactive Ross River clay and flood-affected blocks, pavers on a flexible bed ride ground movement and can be lifted and relaid if a section settles, while a properly built, cyclone-appropriate concrete slab spans soft ground better and will not wash out or lift in a big wet. Near the coast, both need the steel or sub-base protected from salt. Here is how to weigh them up.
A concrete driveway is one rigid, bonded surface. Once it is poured, reinforced and jointed, it acts as a single slab that bridges over soft spots in the ground beneath it. Pavers are the opposite: many small units laid on a compacted sub-base and a flexible sand bed, locked together by their edges and the sand in the joints. The whole idea is that the surface can flex a little without failing.
That single distinction, rigid slab versus flexible field of units, drives almost every trade-off below, and it matters more in Townsville than in a place with stable, well-drained ground.
Reactive Ross River clay. Through the older flats and the low ground near the river, the black-soil clay swells when the wet season soaks it and shrinks back hard through the dry. That movement is what lifts and cracks slabs that were not built for it. Pavers are more forgiving here, because each unit can shift a fraction on its sand bed without cracking, and a settled patch can be lifted and relaid at a fraction of the cost of a slab repair. A concrete slab handles the same clay a different way, through an engineered base, steel and control joints that keep the movement under control. Both work when they are built for the ground.
Flood-prone, low blocks. On the flood-affected ground the 2019 monsoon reminded everyone about, a well-built concrete slab has the edge in a big wet. It is one bonded surface that will not wash out or have its bedding sand scoured away the way a flooded, poorly bedded paver drive can. The catch is that the slab has to be set at the right flood-aware height with proper falls and drainage, so it sheds water rather than sitting in it. Get the level right and concrete is the more flood-resilient of the two.
Cyclone country and salt. The whole city sits in cyclonic wind Region C, and near the water at North Ward and Bushland Beach the salt air is relentless. A concrete slab that abuts a structure needs edge and tie-down detailing to suit cyclonic loads. And whichever surface you choose, salt is the long-term enemy: a concrete slab needs enough cover over the steel and a coastal-suitable mix, while pavers need a sub-base and edge restraints that will not corrode away. Salt zones need protection either way.

It depends on the ground. On reactive Ross River clay and flood-affected blocks, pavers on a flexible bed can ride the ground movement and be lifted and relaid if a section settles. A properly built, cyclone-appropriate concrete slab spans soft ground better and will not wash out or lift in a big wet. Near the coast, both need the steel or sub-base protected from salt.
Pavers are more forgiving of small ground movements because each unit sits on a flexible sand bed and can shift slightly without cracking, and a settled area can be lifted and relaid. A concrete slab is rigid, so on reactive clay it relies on an engineered base, steel and control joints to manage the same movement. Both work when built for the ground, they just handle it differently.
A well-built concrete slab has the edge in a big wet, because it is one bonded surface that will not wash out or float pavers off their bed the way a flooded, poorly bedded paver drive can. The trade-off is that the slab must be set at the right flood-aware height with proper falls and drainage, which is exactly what a local concreter designs for.
A correctly built concrete driveway is close to maintenance-free for decades apart from the odd seal. Pavers can last a long time too, but they need occasional attention: weeds and ants in the joints, re-sanding, and lifting the odd settled unit. Concrete is the lower-fuss surface, pavers are the more repairable one.
