Exposed aggregate concrete on the Sunshine Coast

Decorative stone finishes for driveways, patios and pool surrounds, washed to reveal the aggregate and sealed for colour and grip.

$135 to $150 per m², supplied and laid. Prices may vary with site conditions and variations; the written quote after a site measure is fixed.

Exposed aggregate is concrete finished so the decorative stone within it shows at the surface: poured, screeded, then washed back and sealed. On the Sunshine Coast it has become the default street facing finish for a reason. It reads as designed rather than poured, it grips when the afternoon storm comes through, and the estate covenants that shape the region’s new suburbs generally steer driveways away from plain grey altogether.

Where it goes

  • Driveways: the whole frontage in one finish, or borders and feature panels against plain concrete to manage the budget. See concrete driveways for the build standard underneath.
  • Patios and alfresco areas: a surface that carries the indoor outdoor look without tiles, covered on the patios page.
  • Pool surrounds: texture underfoot and a finish that ties the pool into the landscaping, covered on the pool surrounds page.

Stone against the house, not from a brochure

The difference between exposed aggregate that lifts a house and a surface that fights it is the blend. Stone size, stone colour and the cement tone around it all change the read. Selection happens with sample boards at the site measure, in daylight, against the render and roof they will live with.

Sealed after cure

Once the surface has cured it is sealed for colour depth, stain resistance and grip. Sealer choice depends on the setting: full sun driveways, covered alfresco slabs and wet pool edges each get what suits them. Coastal sun is hard on any surface, so resealing every few years keeps the finish deep; the interval is covered at handover.

What it costs

Exposed aggregate sits at the top of the concrete range because of the stone and the extra finishing stages, and the rates guide shows how it compares with plain and coloured work. Prices may vary with site conditions and variations; the written quote after a site measure is fixed.

How a job runs

Five stages, each signed off before the next

  1. 01

    Site measure

    The block, the levels, the access and the ground, measured on site. Finishes compared against your house in daylight, not from a brochure.

  2. 02

    Written quote

    One fixed written quote for the scope measured. Any crossover or covenant approvals your job needs are identified here, before anything is booked.

  3. 03

    Form and set out

    Boards to string lines, levels checked twice, base compacted to suit the ground, steel on chairs. The day that decides how the job turns out.

  4. 04

    Pour and finish

    Poured, screeded and finished in one continuous operation, timed for the weather. The finish you chose, applied when the surface is ready for it.

  5. 05

    Cure and handover

    Concrete is kept curing, joints are cut on time and sealing follows once the surface has settled. Care and reseal intervals are covered at handover.

Questions

Exposed aggregate questions

Why is exposed aggregate the common choice on the Sunshine Coast?

It suits the market and the rules. The finish reads as architectural stone rather than plain concrete, it keeps grip when wet, and in estates like Aura and Harmony the design covenants generally do not permit undecorated grey, so decorative finishes are the practical path to approval.

Is exposed aggregate slippery around a pool?

The exposed stone gives more texture underfoot than a trowelled surface, and sealers are chosen for the setting, with slip resistance considered where the surface stays wet. Pool surrounds are covered in detail on the pool surrounds page.

How is the stone chosen?

From sample boards against your house in daylight. Blends vary in stone size and colour, from creams and warm buffs that suit coastal renders through to charcoals. The mix that looks right against your render, roof and landscaping is the one that goes in the truck.

Does exposed aggregate need resealing?

Sealer life depends on traffic and sun, and on the coast the sun works surfaces hard. Expect to reseal every few years to keep the colour deep and the surface protected; the interval for your surface is covered at handover.
