Two complementary stone colours combined for contrast and depth.
Why people choose it
- Strong street appeal, especially on driveways
- Good for highlighting borders or feature strips
- Suits contemporary builds particularly well
Worth knowing
- Needs precise installation to keep the contrast even
- Can look out of place on a heritage-style home
- Sits at a higher price point than standard mixes
Fine Stone Exposed Aggregate Mix
Smaller stones for a smoother, more refined finish that still holds its grip.
Why people choose it
- Sleeker, more minimal look
- More comfortable underfoot — popular around pools and patios
- Still slip-resistant, just less coarse
Worth knowing
- Less dramatic visually than larger stone blends
- Can need more frequent cleaning
- Slightly less drainage between the smaller stones
What a Properly Installed Exposed Aggregate Surface Should Give You
- Street appeal that lasts. A well-matched mix works with your home’s colours and landscaping instead of fighting them — and natural stone variation means no two driveways look exactly alike.
- Strength built for Melbourne conditions. Concrete keeps gaining strength for up to 28 days after the pour. Correctly placed reinforcement and control joints reduce cracking risk, and a mix suited to our clay soils and weather swings holds up far longer than a generic pour.
- Genuine slip resistance. The exposed texture grips well in the wet — useful on sloped driveways or shaded paths that don’t dry out quickly.
- Low, manageable upkeep. Periodic cleaning and resealing is really all it needs. Done properly, it won’t need patching or resurfacing for years.
What Actually Shapes the Right Choice for Your Property
- Melbourne’s climate. Four seasons in a day is a real thing here — heat, sudden rain, and temperature swings all affect how a surface performs over time. Drainage and sealing need to be planned around it, not added as an afterthought.
- Your soil. Reactive clay soil is common across Melbourne’s suburbs and moves as moisture levels change. Without proper compaction and reinforcement, even a beautifully finished driveway can crack or shift.
- How the surface will be used. A driveway carrying daily vehicle traffic needs a different thickness and reinforcement plan than a garden path or pool surround. This should drive the spec, not just the look.
- Your home’s design. Stone size, colour, and layout should sit comfortably with your facade and landscaping rather than compete with it.
- Long-term cost, not just upfront price. A cheaper quote that skips proper base prep or reinforcement often costs more down the track in repairs.
How to Choose the Right Concreter (Not Just the Right Mix)
- Look at real, completed work. Photos of finished projects — clean edges, even stone exposure, consistent colour — tell you more than any sales pitch.
- Ask about site prep. Excavation depth, base material, compaction and drainage planning are what determine whether a driveway lasts 5 years or 25. A concreter who can walk you through this process clearly is one who takes it seriously.
- Understand the mix and materials. Ask where the stone comes from, how colour consistency is managed, and what sealant is used. A concreter who brings physical samples to site is letting you make an informed decision, not a guess from a photo.
- Check licensing and insurance. This protects you as much as it protects the business. A reputable concreter will explain this without you having to ask twice.
- Compare full quotes, not just the bottom line. Look at what’s actually included — prep, reinforcement, sealing, finishing — rather than comparing one number against another.
- Notice how they communicate. Prompt, clear answers during the quoting stage are usually a good sign of how the job itself will run.
What Affects the Cost of Exposed Aggregate Concrete
Main cost factors:
- Site preparation — soil conditions, excavation depth, machinery access
- Base construction — thickness and compaction of the crushed rock base
- Reinforcement — mesh or bar systems for structural strength
- Stone selection — standard blend vs custom or two-tone design
- Surface area and layout — including borders or feature detailing
- Drainage requirements — compliance with council stormwater rules
- Sealing and finishing

FAQs
How long does exposed aggregate concrete take to cure?
It’s generally safe to walk on after 24–48 hours, but full strength takes around 28 days. We recommend keeping vehicles off a new driveway for at least 7 days, longer if weather has been wet or cold.
Does exposed aggregate need to be sealed?
Yes. Sealing protects the surface from stains, moisture and general wear, and it’s what keeps the colour looking fresh. Most surfaces need resealing every 2–3 years depending on traffic and exposure.
Which mix is best for a Melbourne driveway?
It depends on your soil, slope and how much traffic the driveway gets, but a standard or custom mix with proper reinforcement handles daily vehicle use well. We can recommend the right option once we’ve seen your site.
Can exposed aggregate crack?
Any concrete surface can crack if the base isn’t prepared correctly, especially on Melbourne’s reactive clay soils. Proper excavation, compaction, reinforcement and control joints are what prevent this — it comes down to installation quality more than the mix itself.
How much does exposed aggregate cost per square metre in Melbourne?
Typically $100–$220+ per m², depending on the mix, site conditions and any custom detailing. See the pricing table above for a full breakdown.
Is exposed aggregate slippery when wet?
No — the exposed texture actually improves grip compared to plain concrete, which is why it’s a popular choice for driveways, paths and pool surrounds.
How long does an exposed aggregate installation take?
Most residential driveways or patios take 1–3 days to pour, plus curing time before full use. Larger or more complex jobs may take longer — we’ll give you a clear timeline in your quote.
