Exposed Aggregate Cost Per m2 Perth (2026 Price Guide)
Exposed aggregate concrete typically costs $100–$150 per m2 in Perth, installed. For a standard residential driveway, that means a total project cost somewhere between $4,200 and $9,900, depending on size, site conditions, and aggregate choice. This guide breaks down exactly what drives that range and what a fair quote looks like.
| Type | Cost per m2 | 42m2 driveway | 66m2 driveway |
|---|---|---|---|
| Standard exposed aggregate | $100–$150 | $4,200–$6,300 | $6,600–$9,900 |
| Premium/custom aggregate | $150–$200+ | $6,300–$8,400+ | $9,900–$13,200+ |
| Plain brushed concrete (comparison) | $60–$85 | $2,520–$3,570 | $3,960–$5,610 |

Exposed Aggregate Concrete Cost Per m2 in Perth — 2026 Rates
The standard rate for aggregate concrete in Perth sits at $100–$150 per m2. That range is wide for a reason — the variables that push you from $100 to $150 are real and worth understanding before you get your first quote.
At the lower end, you’re looking at a straightforward job: standard pea gravel aggregate, flat site, easy access, one sealer coat. At the upper end, you’re dealing with premium aggregate mixes, deeper sub-base requirements, or a larger driveway where finisher time per metre increases.
What’s Typically Included in the Per-m2 Rate
A properly scoped quote at $100–$150/m2 will cover:
- Supply of ready-mix concrete and aggregate material
- Labour: excavation, formwork setup, pour, finishing, and aggregate exposure (washing or brushing the surface)
- Standard sub-base preparation — compacted roadbase or sand to standard residential depth
- Single coat solvent-based sealer
- Formwork and site cleanup
That’s a complete installation. If a quote is significantly below $100/m2 and claims to include all of this, something is being cut short — usually sub-base depth or sealer quality.
What’s Usually Extra (Check Your Quote)
These costs are common but frequently left out of initial quotes. Always ask before signing:
- Demolition and removal of your existing driveway: $40–$80/m2
- Second sealer coat or upgrade to UV-stable / colour-enhancing sealer: $5–$15/m2
- Custom aggregate (crushed quartz, granite, recycled glass, custom colour blend): add $15–$40/m2
- Decorative saw-cut joints or coloured edging: $10–$25/m2
- Crossover reinstatement (council requirement when the driveway crosses a verge): $500–$1,500 flat
- Access surcharges (tight side access, steep crossover, pump hire required): $600–$1,500
Crossover reinstatement catches a lot of Perth homeowners off guard. If your driveway crosses council verge, you’re legally required to reinstate it to council spec — and that cost often doesn’t appear in a first quote. Ask upfront.
Real Driveway Totals — What Perth Homeowners Actually Pay
Per-m2 figures are a useful benchmark, but they don’t tell you what you’re actually going to write a cheque for. Here are the real dollar totals for common Perth driveway sizes.
Single Driveway Costs (Perth Standard Sizes)
| Driveway Dimensions | Area | Standard ($100–$150/m2) | Premium ($150–$200/m2) |
|---|---|---|---|
| 3.0m × 14m (narrow single) | 42m2 | $4,200–$6,300 | $6,300–$8,400 |
| 3.5m × 15m (standard single) | 52.5m2 | $5,250–$7,875 | $7,875–$10,500 |
Double Driveway Costs (Perth Standard Sizes)
| Driveway Dimensions | Area | Standard ($100–$150/m2) | Premium ($150–$200/m2) |
|---|---|---|---|
| 5.5m × 12m (standard double) | 66m2 | $6,600–$9,900 | $9,900–$13,200 |
| 6.0m × 15m (large double) | 90m2 | $9,000–$13,500 | $13,500–$18,000 |
If you’re replacing an existing driveway, add $4,000–$8,000 for demolition and removal of the old slab. That figure depends on slab size, thickness, and disposal costs.
A typical Perth homeowner replacing a standard single driveway with exposed aggregate should budget $8,000–$14,000 all up once demo is included. That’s the realistic number to take into your planning.
What Drives the Cost of Exposed Aggregate Up (or Down)?
Two quotes for the same driveway can be $3,000–$5,000 apart. Here’s what’s actually behind that.
| Factor | Cost Impact | Notes |
|---|---|---|
| Aggregate type and size | +$0–$40/m2 | Pea gravel = cheapest; crushed quartz/granite = mid; custom blends = premium |
| Slab thickness | +$10–$25/m2 | 100mm standard; 125mm for vehicles over 2.5 tonnes |
| Site excavation depth | +$10–$30/m2 | Perth clay soils may require deeper cuts |
| Slope / access difficulty | +$10–$30/m2 | Pump hire, extra formwork, steep crossover |
| Driveway size (economies of scale) | -$5–$15/m2 | Larger jobs often attract volume pricing |
| Sealer specification | +$5–$15/m2 | UV-stable sealer strongly recommended for Perth |
| Crossover reinstatement | +$500–$1,500 flat | Not always included — ask upfront |
| Demo and removal | +$40–$80/m2 | Only if replacing an existing slab |
Aggregate type is the biggest lever on price and appearance. Standard pea gravel gives you a clean, uniform look at the bottom of the range. Step up to 10mm or 14mm crushed granite or quartz and the look improves significantly — but so does the cost. Custom colour-blended aggregate can add $30–$40/m2. Be specific about what you want before comparing quotes, otherwise you’re comparing different products.
Sub-base preparation is where corners get cut in Perth. The Swan Coastal Plain is reactive clay country. A proper sub-base — typically 100mm of compacted roadbase or sand — costs money that a cheap quote skips. Driveways that crack within five years almost always trace back to inadequate sub-base, not the concrete itself. If one quote is substantially cheaper than the others, ask what depth and material they’re using for sub-base.
Small jobs cost more per square metre. A 25–30m2 job attracts a minimum call-out component that inflates the effective per-m2 rate. If you’re pouring a compact driveway, expect to land at the upper end of the range — closer to $130–$150/m2 — even for a straightforward job. Larger jobs (80m2+) can attract volume pricing, sometimes $5–$15/m2 less than standard.
Exposed Aggregate vs. Other Driveway Finishes — Perth Cost Comparison
Here’s how exposed aggregate stacks up against the other common driveway options Perth homeowners consider.
| Finish | Cost/m2 (Perth) | Lifespan | Maintenance | Perth Heat Performance | Best For |
|---|---|---|---|---|---|
| Exposed Aggregate | $100–$150 | 30–40 yrs | Low | Good — textured surface handles UV well | Kerb appeal, resale value, family driveways |
| Liquid Limestone | $80–$120 | 25–35 yrs | Medium | Excellent — cooler surface, light colour reflects heat | Barefoot families, pools, light aesthetic |
| Plain Brushed Concrete | $60–$85 | 25–30 yrs | Low | Moderate | Budget-first, functional applications |
| Stamped/Coloured Concrete | $100–$150+ | 25–35 yrs | Medium | Moderate | Decorative, feature driveways |
| Asphalt | $35–$55 | 10–20 yrs | High | Poor — softens in Perth summer heat | Not recommended for Perth residential |

Is Exposed Aggregate Worth the Extra Cost in Perth?
Yes — if kerb appeal and long-term low maintenance are priorities. The $40–$65/m2 premium over plain brushed concrete is real, but exposed aggregate holds its appearance far longer and adds more to resale value than a plain slab.
The main alternative to weigh up is liquid limestone. It’s cheaper and runs cooler underfoot in Perth’s summer — a genuine advantage if your family walks barefoot from the car to the front door. Exposed aggregate gets hot on bare feet in summer, which is worth knowing before you commit.
If the budget is tight and the driveway is purely functional, plain brushed concrete is a solid, proven option that will last 25–30 years with minimal upkeep. It’s not a compromise — it’s just a different priority.
Can You Resurface an Existing Driveway with Exposed Aggregate?
Yes, in some cases. If your existing slab is structurally sound, an aggregate overlay can give you a similar finish at significantly lower cost than full replacement. This is the option a lot of Perth homeowners don’t know they have.
When an Aggregate Overlay Works
- Your existing slab is structurally sound — no major cracking, no movement, no drainage issues
- The surface is faded, worn, or aesthetically outdated but the base underneath is solid
- Aggregate overlay costs $50–$100/m2 — compared to $100–$150/m2 for full replacement
- Faster installation, no demolition cost, no removal and disposal of the old slab
For the right slab, concrete driveway resurfacing in Perth is a legitimate and cost-effective path to the exposed aggregate look.
When You Need Full Replacement
An overlay will not fix structural problems. If any of the following apply, you need full replacement:
- Cracked slab with movement or uneven sections
- Root damage beneath the slab shifting the surface
- Poor original sub-base causing flex or drainage problems
Resurfacing over a failing slab is a waste of money. The cracks and movement in the base will telegraph through the overlay within a few years.
Simple Decision Tree
Not sure which path is right for you? Work through this:
- Your slab is cracking or uneven → full replacement
- Your slab is sound but looks old and faded → overlay resurfacing is viable
- Your driveway has drainage problems → concrete driveway repairs first, then reassess
- You’re not sure of your slab’s condition → get a structural assessment before committing to either option
How to Know If Your Exposed Aggregate Quote Is Fair
A proper quote tells you exactly what you’re getting. If it doesn’t, you can’t compare it to anything else.
What a Proper Quote Should Include
A thorough exposed aggregate quote will specify each of these as a line item:
- Excavation and sub-base preparation — depth and material named (e.g., “100mm compacted roadbase”)
- Concrete grade and volume — minimum 32 MPa for residential driveways
- Aggregate type, size, and colour
- Slab thickness
- Sealer type — brand and product specification
- Formwork and cleanup
- Crossover reinstatement — included or explicitly excluded
- Demolition and removal — as a separate line item if your existing slab is being replaced
If a quote just says “supply and lay exposed aggregate driveway — $X” with no further detail, that’s not a quote. It’s a number with no contract behind it.
Red Flags in a Quote
Watch out for these:
- Contractor quotes a price without visiting your site
- Rate under $90/m2 (sub-base preparation is being cut)
- No mention of sealing anywhere in the quote
- “Exposed aggregate driveway” with no specification of aggregate type or size
- Day rate rather than a fixed price
- No mention of crossover reinstatement when your driveway crosses a council verge
A contractor who won’t specify their aggregate mix or sealer product before the job starts won’t be easy to deal with after it finishes.
Quote Comparison Checklist
Use this before you sign anything:
- Did the contractor visit the site before quoting?
- Is the quote a fixed price — not a day rate or estimate?
- Does it specify aggregate type, size, and colour?
- Does it specify concrete grade (MPa) and slab thickness?
- Is sealing included, and is the product named?
- Is crossover reinstatement included or explicitly excluded?
- Is demolition and removal a separate line item (if applicable)?
- Are there any listed exclusions you need to clarify before proceeding?
Get a minimum of three fixed-price quotes from contractors who have visited your site. Driveway installation scope varies more than most people expect — a site visit is the only way to price it accurately.
Perth-Specific Factors That Affect Exposed Aggregate Performance
This is where Perth differs from every national guide you’ll read. The conditions here are specific and they matter.
Reactive clay soils are the biggest variable. Perth’s Swan Coastal Plain is reactive clay. Without adequate sub-base preparation, the slab will move as the soil expands and contracts with moisture. A minimum of 100mm compacted roadbase or sand is standard — some sites in higher-clay areas need more. This is not a corner to cut. Most premature driveway failures in Perth trace back to inadequate sub-base, full stop.
UV exposure in Perth is extreme. Sealers that perform fine in Melbourne will degrade and yellow faster here. Specify a UV-stable sealer when you’re getting quotes — it costs $5–$15/m2 more but extends the sealer life from 3–4 years to 5–7 years. A yellowed or peeling sealer looks worse than no sealer at all.
Perth has no freeze-thaw cycles. This is actually good news. The crack mechanism that destroys concrete driveways in Canberra or the Blue Mountains — water freezing inside the slab and expanding — doesn’t exist in Perth. A well-installed exposed aggregate driveway here can comfortably last 30–40 years, longer than equivalents in most other Australian capital cities.
Summer scheduling matters. Pouring concrete in peak Perth summer heat (December to February) requires careful management — early morning starts, adjusted water-to-cement ratios, and proper wet curing. Reputable contractors manage this as standard. If you’re planning a new driveway, booking for autumn or spring (March to May, or August to October) gives the best curing conditions and is worth considering if timing is flexible.
FAQ — Exposed Aggregate Driveway Cost Perth
How much does exposed aggregate cost per m2 in Perth?
Exposed aggregate concrete costs $100–$150 per m2 installed in Perth for a standard residential driveway. Premium aggregate types or complex sites can push the rate to $150–$200/m2. This typically includes supply, labour, standard sub-base preparation, and a single coat sealer.
What is the total cost of an exposed aggregate driveway in Perth?
A standard single driveway (around 42–52m2) typically costs $4,200–$7,875 installed. A double driveway (66–90m2) costs $6,600–$13,500. If you’re replacing an existing driveway, add $4,000–$8,000 for demolition and removal of the old slab.
Is exposed aggregate more expensive than plain concrete in Perth?
Yes. Plain brushed concrete costs $60–$85/m2 in Perth, while exposed aggregate runs $100–$150/m2 — a premium of roughly $40–$65/m2. For a standard 50m2 driveway, that’s an extra $2,000–$3,250 for the exposed aggregate finish.
How long does exposed aggregate last in Perth?
A properly installed exposed aggregate driveway in Perth will last 30–40 years. Perth’s lack of freeze-thaw cycles extends concrete lifespan compared to southern states. The sealer needs refreshing every 3–7 years depending on the product used and UV exposure.
Does exposed aggregate need to be sealed in Perth’s climate?
Yes. Sealing is essential in Perth due to high UV exposure. A UV-stable penetrating or topcoat sealer protects the surface from UV degradation, enhances the aggregate colour, and makes the surface easier to clean. Budget for resealing every 3–7 years.
Can I get an exposed aggregate overlay instead of a full replacement?
Yes, if your existing slab is structurally sound. An aggregate overlay costs $50–$100/m2 — significantly cheaper than full replacement at $100–$150/m2. It’s not suitable for cracked, uneven, or moving slabs. Have a contractor assess your slab condition before committing to either option.
