What we finish

Three surfaces, one finish, done to a standard

The moment it becomes itself

The first seal

Washed stone dries dusty and pale. The first coat of sealer is where the finish arrives: the colour deepens, the stone goes glassy and the surface you chose on the sample board finally looks back at you. Scroll, and watch it happen.

Stone and colour

Stone, chosen to the house

Drawn as a guide to tone, not a promise of a product. Blends are confirmed on sample at the site measure, matched to your render, roof and landscaping.

The full library, and how a blend is chosen

Aura · Harmony · covenant estates

Where plain grey is not permitted

Thousands of the coast's newest driveways sit on covenant land. In Aura, the design essentials for each release generally rule out plain and painted concrete finishes; Harmony's guidelines exclude undecorated grey broom finish, and its driveways are expected done within a tight window of handover. Decorative concrete is not the upgrade in these estates, it is the requirement.

That is this site's home ground. The blend is chosen to your facade palette, the covenant paperwork's finish requirements are read before the quote is written, and the wording that governs your block, which varies by release, is checked in your estate's design guidelines rather than assumed. The Baringa, Nirimba, Bells Creek and Palmview pages cover the estate detail suburb by suburb.

How the finish happens

Six stages, and one hour that decides everything

Exposed aggregate is unforgiving of shortcuts because the finish IS the structure on show. The reveal happens once, at one window in the cure, and cannot be redone. That is why the process matters more here than on any other concrete surface.

  1. 01

    Measure and design

    The site measure settles levels, falls and access, and the stone and colour conversation starts against your render, roof and landscaping, with sample boards where the choice is close.

  2. 02

    Form and prepare

    Excavation to a stable base, compacted to suit the ground, formed to neat lines with steel mesh on chairs. The surface only ever looks as good as what carries it.

  3. 03

    Pour the decorative mix

    A 25 MPa mix batched with the chosen stone through it arrives and is placed, screeded and floated without overworking the surface.

  4. 04

    Hold the surface

    A surface retarder goes on behind the float so the paste at the top stays soft while the slab below begins its set. Timing here is the craft.

  5. 05

    The wash

    At the right hour the surface is washed and the paste lifts away to an even, consistent reveal. Too early is patchy, too late is buried; even is everything.

  6. 06

    Cure and seal

    The slab cures, control joints are cut on time, and sealer brings the colour up and locks the surface. Traffic stays off for seven days.

The specification

Numbers the finish stands on

A beautiful surface on a poor slab is a short story. Under every finish this site quotes sits the same specification, written into the quote and detailed on the finish standard.

Where we work

Beach streets to hinterland ridges, one crew

Every suburb page is written for its streets: the estates and their covenants, the salt, the shade, the soil under the slab. The service area in full.

Before you decide

Exposed aggregate on the coast, answered

What does exposed aggregate cost on the Sunshine Coast?

Driveways and patios run $135 to $150 per m2 supplied and installed, pool surrounds $140 to $180. A typical single driveway of about 45 m2 lands between $6,075 and $6,750. Every figure on this site is a guide until the site has been measured; the written quote that follows it is the number that holds.

Why is exposed aggregate the coastal finish?

It grips when wet, which the coast tests every summer storm. It breaks glare instead of bouncing it. It hides the tyre marks, sand and leaf stain that show on plain concrete within a year. And in the estates it is usually what the design covenants expect, since undecorated plain grey is generally not permitted in Aura or Harmony.

Do we get to choose the stone?

That choice is most of the point. The stone library covers the blend families, pale coastal whites through to near-black, and the recommendation is made against your render, roof and landscaping at the site measure, with sample boards where a decision is close. Blends are confirmed on sample, not from a screen.

Are you licensed?

Yes. Concreting work valued over $3,300 requires a QBCC licence in Queensland, and the contractor holds one and is insured.

How long does the job take?

Most driveways and patios are two visits across a week: excavation, base and formwork first, then the pour, wash and joint cutting. Sealing follows once the slab has dried out. Foot traffic is fine the next day, cars stay off a driveway for seven days.

Begin with a site measure

The finish that gets chosen for how it looks deserves a quote written the same way.
