Home › Guides › Exposed Aggregate vs Plain Concrete
For most exposed driveways, pool surrounds and paths in Townsville, exposed aggregate is the better all-rounder, because it grips underfoot in the wet season, tolerates salt air near the coast and a lighter stone stays cooler underfoot in the tropical heat. Plain grey concrete is still the right call where cost matters most and the surface is sheltered and flat. Here is how the two compare so you can pick the finish that suits your block.
Both start as the same slab, poured on the same base with the same steel. The difference is only the top few millimetres. Plain grey concrete is trowelled or broomed to a smooth or lightly textured finish and left as it comes. It is the default, and it does the job on a sheltered driveway or a shed apron.
Exposed aggregate uses a mix with decorative stone through it. Once the slab has set enough, the top layer of cement paste is washed back to reveal the pebbles underneath, leaving a textured, stony surface. You choose the stone, so the colour and look can be tuned to the house. It costs more because of the extra process and the care it takes on the day, but around Townsville it earns that cost back in three ways that matter in this climate.
Three local realities push a lot of Townsville jobs towards exposed aggregate.
Grip in the wet season. From December to March the monsoon can drop serious rain in a short burst, and a smooth, hard-trowelled plain slab gets slick when it is running with water. Exposed aggregate has texture built into the surface, so it holds grip on a sloped driveway and around a wet pool edge when a plain finish would be slippery. That is exactly why it is the standard choice around Townsville pools.
Salt tolerance near the coast. Homes near the water at North Ward, Bushland Beach and along the Strand sit in salt-laden air. The stony exposed surface copes with that salt exposure well, and a seal helps further. It is a finish that ages gracefully in a coastal setting rather than showing every mark.
Cooler underfoot. In the build-up and through summer, surface temperature matters when you are walking to the pool barefoot. A lighter-coloured aggregate reflects more heat than a dark plain slab and stays cooler underfoot, which is a genuine comfort difference in the tropics. Choose a pale stone and a pool surround becomes usable in the middle of the day.
Exposed aggregate is not automatically the answer. Plain grey concrete wins when:
Whichever surface you choose, near the coast the steel underneath still needs enough concrete cover and a salt-suitable mix. Salt attacks the reinforcement, not the finish, so the protection that counts happens below the surface either way.

The finish is a conversation worth having on site, where a concreter can see the slope, the sun and how close you are to the water. Call 0482 392 415 or send the details through the contact page and we will match you with a local crew.

Plain grey is still the sensible choice where cost is the priority and the surface is sheltered and flat.
No, that is one of its main advantages here. Washing back the surface to expose the stone gives a textured, non-slip finish that holds grip during the heavy wet-season downpours and around wet pool edges, where a smooth trowelled plain slab can get slick.
The exposed stone surface copes well with the salt-laden air near North Ward, Bushland Beach and the Strand, and sealing helps further. Whichever finish you choose near the coast, the steel underneath still needs enough concrete cover and a salt-suitable mix, because salt attacks the reinforcement, not the surface texture.
Plain grey concrete is the cheapest finish. Exposed aggregate costs more because of the washing-back process, the stone selection and the extra care on the day. As an indicative figure, plain sits around $80 to $120 per square metre supplied and laid and exposed aggregate around $120 to $170, though every job needs a site visit.
