What Does Exposed Aggregate Concrete Cost in 2026?
Exposed aggregate concrete typically costs $100 to $150 per m² supplied and laid across Australia in 2026. A standard single driveway of 40 to 50 m² generally totals $5,000 to $9,000 once you factor in site prep, excavation, formwork, reinforcement and finishing. Prices vary significantly by state, access conditions, stone type and slab thickness. Always get a written quote before committing.
Exposed aggregate is one of the more popular decorative finishes in Australia because it holds up well in our climate, provides reasonable slip resistance and looks good with minimal ongoing maintenance. The process involves pouring a standard concrete mix seeded with decorative aggregate, then washing or brushing the surface before the concrete fully cures to expose the stones.
The finish costs more than plain broom-finished concrete ($65 to $90 per m²) because it requires more skilled labour, a retarder chemical, pressure washing at the right time and usually a sealer coat. Get that timing wrong and the whole pour can be wasted, which is why experienced contractors charge accordingly.
If you are comparing quotes, make sure each one specifies the aggregate type, stone size, slab thickness, whether a sealer is included and what the minimum call-out applies. These details change the final number considerably.
Exposed Aggregate Price Table by Finish and Job Type
The table below gives realistic installed price ranges for common exposed aggregate applications. These are general market figures only. Your actual quote will depend on site conditions, contractor availability and regional labour costs.
| Application / Finish | Typical Range (per m²) | Notes |
|---|---|---|
| Standard exposed aggregate (river pebble) | $100 - $130 per m² | Most common residential finish, widely available aggregate |
| Premium exposed aggregate (quartz, basalt, granite) | $120 - $150 per m² | Decorative stone costs more; some imported mixes add further cost |
| Seeded / topping aggregate over a structural base | $110 - $150 per m² | Thin aggregate topping on reinforced slab; popular for pool surrounds |
| Plain broom finish (for comparison) | $65 - $90 per m² | Standard finish with no decorative aggregate |
| Coloured or stamped concrete (for comparison) | $100 - $150 per m² | Similar price bracket but a different look and process |
| Exposed aggregate driveway (40-50 m², full job) | $5,000 - $9,000 total | Includes excavation, formwork, mesh, pour and sealer |
| Exposed aggregate path or entertainment area (20-30 m²) | $2,500 - $5,000 total | Less excavation typically needed; minimum call-out may apply |
Small jobs under roughly 15 m² often attract a minimum charge. Most concreters set that minimum at around $1,500 to $2,000 regardless of area, so the effective per-m² rate on tiny jobs can look very high.
What Drives the Cost Up (or Down)?
The per-m² rate is only part of the story. Several site-specific factors can push a quote well above the base rate, or occasionally below it on a large straightforward job.
Excavation and Ground Preparation
If the ground needs digging out, levelling or compacting, that adds cost. Rocky ground, clay soil that needs stabilisation, or a sloped block can all increase excavation charges. Expect to pay more if a bobcat or excavator is required versus a job where preparation is mostly manual.
Formwork
Formwork (the timber or steel framework that holds the wet concrete in shape) is usually included in quotes for straightforward rectangular slabs. Curved paths, non-rectangular areas or complex borders take longer to form up and add labour time.
Reinforcement
A driveway meant to take vehicle loads needs steel reinforcing mesh or reo bar. Footpaths and lightly used paths may not require it. Reinforcement adds roughly $15 to $30 per m² depending on the specification.
Slab Thickness
A standard residential driveway is typically 100 mm thick. Heavier vehicle areas, commercial sites or areas with poor subgrade may need 125 mm or 150 mm. More concrete means more cost.
Aggregate Type and Stone Size
River pebble is the most affordable and widely available option. Quartz, basalt chips, recycled glass or imported decorative stones all cost more. Stone size affects the look and the labour involved in achieving an even exposure depth.
Site Access
Difficult access, narrow gates, steep driveways or back-yard jobs that require pumping concrete (instead of direct chute delivery) add to the bill. Concrete pump hire typically adds $400 to $900 to a job.
Sealing
A penetrating or film-forming sealer is strongly recommended for exposed aggregate. It protects against oil stains, leaf tannins and weathering. Some quotes include it; many do not. Sealing typically adds $15 to $30 per m².
Council Crossover Requirements
In most states, replacing or modifying the section of driveway that crosses the nature strip (the council crossover) requires a permit and must meet specific standards. This can add several hundred dollars to the project in fees and extra work.
Do not assume sealing is included in a quote. Ask specifically. Unsealed exposed aggregate on a driveway will absorb oil, stain from leaf litter and start to look tired within a year or two. The upfront sealing cost is minor compared to having to grind or replace the surface later.
Prices Around Australia: State and City Variations
Labour and material costs are not uniform across Australia. The following gives a general sense of regional variation, though individual contractor pricing can differ from these patterns.
Sydney and New South Wales
Sydney tends to sit at the higher end of the national range. Labour rates are elevated, and busy contractors in inner-ring suburbs often have longer lead times. Expect to pay closer to $120 to $150 per m² for a quality exposed aggregate finish in Sydney, with excavation and access costs frequently adding to that. Regional NSW is generally cheaper.
Melbourne and Victoria
Melbourne has a well-established concrete trade with plenty of competition, which keeps pricing relatively accessible. Exposed aggregate is extremely popular for driveways in Melbourne's suburbs. Prices commonly sit between $110 and $145 per m². Some specialty aggregate mixes popular in Melbourne (charcoal basalt, pale quartz) can push toward the top of the range.
Brisbane and Queensland
Queensland's hot climate makes curing and retarder timing more critical. Prices are broadly similar to Victoria, around $100 to $140 per m², though in subtropical areas contractors may charge a premium for early-morning pours or very large slabs that need careful management in summer heat. North Queensland can be higher due to supply chains.
Perth and Western Australia
Perth has seen significant construction cost increases since 2022. Exposed aggregate remains popular given WA's indoor-outdoor lifestyle, but material costs and contractor availability have pushed prices to the higher end, often $120 to $150 per m² for residential driveways.
Adelaide and South Australia
Adelaide generally sits slightly below the Sydney and Melbourne price points. Exposed aggregate driveways are common, and competition among concreters keeps pricing reasonable. Expect $100 to $135 per m² for most residential work.
Smaller Cities and Regional Areas
Canberra, Hobart and Darwin each have smaller contractor pools, which can mean less price competition. Regional areas may have lower base labour rates but higher material delivery costs. Getting three quotes matters even more in these markets.
Exposed Aggregate vs Other Concrete Finishes: Is It Worth the Extra Cost?
Exposed aggregate costs roughly 30 to 60 per cent more than plain broom-finished concrete on a per-m² basis. Whether that premium is worth it depends on what you are trying to achieve.
| Finish | Approx Cost (per m²) | Slip Resistance | Maintenance | Lifespan (well-installed) |
|---|---|---|---|---|
| Broom finish | $65 - $90 | Good | Low | 25-40 years |
| Exposed aggregate | $100 - $150 | Very good | Low (seal every 3-5 years) | 25-40 years |
| Coloured / stamped | $100 - $150 | Moderate to good | Medium (resealing needed) | 20-30 years |
| Polished concrete (internal) | $80 - $150 | Low to moderate | Medium | 20-30 years |
Exposed aggregate holds its appearance well over time compared to stamped or stencilled concrete, which can fade or chip. It also provides better traction when wet, which makes it a practical choice for driveways, pool surrounds and steep paths. The trade-off is that repairs are difficult to match, so if a section cracks and needs patching, the patch will usually be visible.
Exposed aggregate is a durable, practical choice for outdoor concrete in Australia. The extra cost over plain concrete is real but the finish typically looks good for decades with minimal maintenance beyond periodic resealing. For high-traffic driveways and pool areas, most concreters consider it the best all-round option in this price bracket.
Maintenance Costs to Factor In
Exposed aggregate is relatively low maintenance, but not zero maintenance. Budget for the following over the life of the surface.
Resealing
A quality penetrating sealer should be reapplied every 3 to 5 years depending on exposure and traffic. Professional resealing of a typical driveway (40 to 50 m²) typically costs $300 to $700 depending on the product used and whether pressure washing is included. DIY resealing is possible with solvent-based sealers sold at trade suppliers, but surface prep matters and a poor application can leave a patchy result.
Pressure Washing
Exposed aggregate traps grit and leaf matter between the stones. An annual pressure wash keeps it looking sharp and prevents organic staining. This is a straightforward DIY task with a decent pressure washer.
Crack Repairs
No concrete surface is immune to cracking over time. Hairline cracks from minor settlement are common and usually cosmetic. Wider cracks may indicate subgrade movement and should be assessed by a concreter. Matching aggregate in a repair is difficult, so repairs are rarely invisible.
How to Get and Compare Quotes
Getting the right price means getting comparable quotes, not just the lowest number.
Get at Least Three Written Quotes
Verbal estimates are not quotes. Ask each concreter for a written quote that specifies the area in m², slab thickness, reinforcement type, aggregate description, whether sealing is included, excavation and disposal, and the expected timeline. Without these details, you cannot meaningfully compare three numbers.
Check Licences and Insurance
In most states, concreters performing work above a certain value must hold a builder's or contractor's licence. Check the relevant state licensing authority (NSW Fair Trading, VBA in Victoria, QBCC in Queensland, etc.) before signing anything. Ask for proof of public liability insurance too.
Understand What Is Excluded
Most quotes exclude council crossover permits and fees, disposal of excess excavated soil, tree root removal, and any extra work discovered once digging starts. Ask each contractor to spell out exclusions clearly.
Timing Can Affect Price
Concreters are busiest in spring and early summer. Getting quotes in late autumn or winter often means shorter wait times and occasionally more competitive pricing, though this varies by region and contractor workload.
Do Not Choose on Price Alone
Exposed aggregate is a skilled pour. The retarder timing, washing pressure and stone exposure depth all require experience. Ask to see photos of recent completed jobs. A poorly done exposed aggregate surface looks uneven and patchy, and there is no easy fix short of grinding it back.
Ask your shortlisted concreters whether they pour and wash the aggregate themselves or subcontract the wash-down to a labourer. The person managing the retarder timing and wash-back should have direct experience with the specific aggregate mix being used.
Frequently Asked Questions
A typical single residential driveway of 40 to 50 m² in exposed aggregate commonly totals between $5,000 and $9,000 in Australia in 2026. That range covers excavation, formwork, reinforcing mesh, the concrete pour, aggregate finish and a sealer coat. The wide range reflects differences in site conditions, aggregate choice, state labour rates and access difficulty. Get a written quote for your specific job rather than relying on averages.
Exposed aggregate concrete generally costs between $100 and $150 per m² supplied and laid in 2026. Standard river pebble finishes tend to sit toward the lower end of that range, while premium stones like quartz, basalt or imported mixes push toward the higher end. Very small jobs may attract a minimum call-out charge of around $1,500 to $2,000 regardless of area.
The extra cost comes from the additional materials (decorative aggregate, retarder chemical, sealer) and the skilled labour required. The surface must be washed or brushed at precisely the right stage of curing to expose the stones evenly. Get the timing wrong and the surface can be ruined. That skill premium, plus the sealer application, accounts for most of the gap between exposed aggregate and plain broom-finished concrete.
Not always. Some concreters include a sealer coat as standard; others quote it separately or leave it to the owner. Always ask specifically whether sealing is included and what product will be used. Sealing exposed aggregate is strongly advisable, particularly for driveways and pool areas, as it protects against oil stains and organic staining from leaves.
A well-installed and properly sealed exposed aggregate surface can last 25 to 40 years. The concrete base itself is durable, and the aggregate is naturally resistant to wear. The main threats to longevity are poor installation (incorrect curing or retarder management), lack of sealing, and subgrade movement causing cracking. Resealing every 3 to 5 years significantly extends the life and appearance of the surface.
Cracks can be structurally repaired, but matching the aggregate in the repair to the surrounding surface is very difficult. Patches are usually visible to some degree. For this reason, minor cosmetic cracks are often left alone after cleaning and sealing the edges. If cracking is widespread or related to subgrade movement, a full assessment by a concreter or structural engineer is a better starting point than patch repairs.
No, it is generally one of the better-performing concrete finishes for wet-weather traction. The exposed stones create a textured surface that provides grip underfoot. This makes it a practical choice for driveways, pool surrounds and external pathways. A high-gloss sealer can reduce that texture slightly, so ask your concreter about matte or low-sheen sealer options if slip resistance is a priority.
In most Australian councils, replacing a driveway that crosses the nature strip (the council verge) requires a permit and must meet the council's crossover specifications. Your concreter should be familiar with local requirements and can often handle the permit application on your behalf, though the fee is typically passed on to you. Check with your local council before work starts to avoid having to remove or redo non-compliant work.
