Exposed Aggregate Cost Perth: What You'll Pay in 2026

If you want a straight answer: exposed aggregate in Perth typically costs between $100 and $180 per square metre , depending on the complexity of the job, the aggregate mix selected, and site conditions. At Woodlands Construct, we have been pricing and installing exposed aggregate across Perth for over a decade, and we believe you deserve honest numbers before you call anyone. No shortcuts. No surprises. Just quality concrete.

This guide covers everything a Perth homeowner needs to know about exposed aggregate pricing in 2026, including a full project cost table, the factors that push prices up or down, and what questions to ask any concreter before signing a quote.

What Is Exposed Aggregate and Why Do Perth Homeowners Choose It?

Exposed aggregate is a decorative concrete finish where the top layer of cement paste is washed away during installation to reveal the natural stones and pebbles within the mix. The result is a textured, slip-resistant surface with real visual appeal.

Perth homeowners choose it for several practical reasons:

• The textured surface stays grippy when wet, which matters around pools and on sloped driveways
• It hides tyre marks and minor staining far better than plain grey concrete
• Quality aggregate mixes from suppliers like Geostone offer consistent colour and stone distribution that holds up in Perth's harsh UV and summer heat
• It suits both new builds in suburbs like Ellenbrook and Baldivis, and driveway upgrades in established areas like Dianella and Karrinyup

Exposed Aggregate Cost Perth: 2026 Price Table

The table below reflects realistic pricing across Perth in 2026. These are installed prices, meaning supply, labour, formwork, and sealing are included. They do not include demolition of existing concrete or significant earthworks.

These ranges reflect standard exposed aggregate mixes. Premium stone selections or custom colour blending will sit toward the upper end. If your project involves demolishing old pavers or an existing slab, budget an extra $50 to $90 per sqm for removal and disposal.

What Drives the Cost of Exposed Aggregate in Perth?

No two quotes will be identical because no two sites are identical. Here are the main factors that move the price:

Aggregate Mix and Stone Selection

The stone blend you choose has a direct impact on material cost. Basic river pebble mixes sit at the lower end. Premium blends using coloured quartz, Tuscan gold, or coastal pebble sourced through suppliers like Geostone or Holcim add $10 to $30 per sqm to the material cost alone. These premium mixes also tend to have tighter colour consistency, which matters when you are covering a large driveway and want a uniform finish across the full pour.

Slab Thickness and Reinforcement

A standard residential driveway uses a 100mm slab with SL72 or SL82 mesh. Areas that carry heavier loads, such as a workshop slab or a driveway that doubles as truck access, need a thicker pour (125mm or more) and additional steel reinforcement. This adds both material and labour cost.

Site Access and Ground Preparation

Tight access in older Perth suburbs like Inglewood or Mount Hawthorn can mean a pump truck is required to get concrete where it needs to go. Pump hire adds roughly $600 to $900 to a job. Soft or reactive soil, common in parts of the Swan Valley and Armadale corridor, may also require additional sub-base compaction or lime stabilisation before pouring.

Sealing

Exposed aggregate must be sealed to protect the finish and make cleaning easier. A quality penetrating sealer applied after cure adds around $8 to $15 per sqm. We always include sealing in our quotes because skipping it leads to staining, fading, and a surface that looks tired within a couple of years.

Job Size

Larger jobs cost less per square metre because the fixed costs of setup, formwork, and concrete truck fees are spread over more area. A 100 sqm pool surround will cost noticeably less per sqm than a 15 sqm pathway poured on its own.

How to Read a Quote and Avoid Undercutters

Perth has no shortage of concreters offering low prices, but cheap exposed aggregate almost always means one of three things: a thinner slab, a lower-grade mix, or no sealing. Ask any concreter you quote with to confirm:

• The concrete strength (look for N32 or N25 minimum for driveways)
• The reinforcement specification (mesh grade and coverage)
• Whether sealing is included and what product they use
• The curing time before vehicle traffic is permitted (typically 7 days minimum)

Woodlands Construct carries a 5-star Google rating because we put all of this in writing before we pour a single metre. Our clients in suburbs like Joondalup, Canning Vale, and Cockburn Central know exactly what they are getting before work starts.

How Long Does the Installation Take?

A standard residential driveway of 40 to 60 sqm takes one to two days of active work. Here is a realistic breakdown of the full timeline:

• Site preparation and formwork: half a day to one full day, depending on existing conditions
• Pour and expose: one day, including the wash-off process to reveal the aggregate
• Initial cure before foot traffic: 24 to 48 hours
• Sealing: typically applied on day three or four once the surface has cured adequately
• Full cure before vehicle traffic: 7 days minimum, 28 days for full structural strength

Weather affects the timeline. Perth summers above 35 degrees Celsius require early morning pours and retarder additives to control the set rate. We schedule our summer pours accordingly and never rush the expose process to meet an artificial deadline.

Frequently Asked Questions

How much does exposed aggregate typically cost in Perth?

The honest range is $100 to $180 per square metre installed, which covers supply, labour, formwork, and sealing. A standard double driveway of around 60 sqm will cost most homeowners between $7,000 and $10,000 fully completed. Premium stone mixes and complex site conditions push costs toward the upper end.

What concrete finish lasts longest in Perth's climate?

Exposed aggregate and honed concrete are both strong performers in Perth's conditions. Exposed aggregate has a natural advantage in UV resistance because the aggregate surface reflects heat rather than absorbing it the way a painted or coloured surface can. Both finishes hold up well to salt air when properly sealed, which is important for coastal suburbs like Cottesloe, Scarborough, and Rockingham. Regular re-sealing every four to six years is the key to longevity with either finish.

How long does exposed aggregate take to install?

Most residential projects take one to two days of active work. Preparation and formwork typically happen on day one, with the pour and expose process on the same day or the next. Allow 24 to 48 hours before foot traffic, three to four days before sealing, and seven days before you drive on it. Full concrete strength develops over 28 days, though the surface will look and feel finished well before that.

Do I need council approval for exposed aggregate in Perth?

For standard residential driveways and patios, council approval is generally not required in Perth. However, if your driveway crosses a verge or kerb, you may need a crossover permit from your local council, which most councils process quickly. Retaining walls above 500mm and some boundary structures have separate approval requirements. We can advise you on what applies to your specific project during the quoting process.
