A driveway says a lot about a home and exposed aggregate has become a popular choice for those after both looks and longevity. In this article, we break down the cost of exposed aggregate driveways, outline key factors that affect the total price, the installation steps, and compare it to plain concrete. We’ve consulted expert concreters Melbourne Concrete Driveways to bring accurate, practical advice based on real-life experience working across Melbourne.
What Does an Exposed Aggregate Driveway Cost?
Exposed aggregate concrete costs between $140 and $220 per square metre, based on verified pricing the final figure will depend heavily on the complexity of the job, finish choice, and site conditions.
- Basic exposed aggregate: $100 – $150 per m²
- Standard aggregate with custom finishes: $110 – $160 per m²
- High-end or decorative mixes: $140 – $220 per m²
According to the team from Melbourne Concrete Driveways, “People are often surprised by the range of finishes available. Some clients opt for locally sourced stone blends, which can cost more but create stunning results.”
How Size and Complexity Affect the Final Price
The shape, slope, and accessibility of your site can quickly push a basic job into premium territory.
- Single car driveway (20m²): ~$2,000 – $3,000
- Double car driveway (35m²): ~$3,500 – $5,250
- Extended or curved driveway: Add 15 – 25% due to additional labour and edging
Access for concrete trucks, demolition of an old surface, or needing to reinforce weak soil can all inflate the base cost.
One common situation the Melbourne Concrete Driveways team encounters is driveways on a slope: “Steep blocks often need extra excavation and formwork. It’s not just about pouring concrete — it’s about doing it so it lasts.”
Common Inclusions and Optional Add-Ons
A typical exposed aggregate driveway installation will include:
- Excavation and site preparation
- Formwork and steel reinforcement
- Concrete pour and aggregate exposure
- Surface sealing
Optional extras may include:
- Additional coats of sealer
- Coloured concrete or custom stone blends
- Integrated drainage or channel grates
- Decorative borders or saw cuts
“Sealing is the most underrated feature,” adds the team. “It’s what protects the finish from oil stains, fading, and surface wear.”
Pros and Cons of Exposed Aggregate Driveways
There are clear reasons this finish remains in demand – but it’s not for everyone.
Advantages:
- Slip resistance: The textured surface improves grip, even when wet.
- Visual appeal: Offers a modern, premium look that enhances kerb appeal.
- Durability: Handles Melbourne’s weather extremes better than many finishes.
Disadvantages:
- Cost: More expensive than plain or broomed concrete.
- Maintenance: Requires resealing every 3 – 5 years.
- Comfort: Rougher underfoot if you plan to walk on it barefoot frequently.
Compared to plain concrete, exposed aggregate costs around 25 – 35% more, but the aesthetic payoff is substantial.
Exposed Aggregate Driveway Installation Process
A proper installation requires skill and timing. Here’s how it’s typically done:
Step 1: Site Preparation
Old surfaces are removed, the area is excavated, and the ground is levelled. Formwork is installed and steel mesh laid.
Step 2: Pouring the Concrete
Concrete is poured and levelled while still wet. Timing is critical here.
Step 3: Exposing the Aggregate
After a short wait, the surface layer of cement paste is washed away using water and a retarder to reveal the stones underneath.
Step 4: Sealing and Finishing
Once dried and cleaned, a sealer is applied to protect the surface and enhance colour.
Each step needs precision. Any delay or misstep can ruin the finish.
Exposed Aggregate Driveway Cost Factors in Melbourne
Several local factors influence pricing in Melbourne:
- Soil type: Areas with reactive clay require thicker concrete or deeper excavation.
- Climate: Hot summers mean faster drying – experienced crews must move quickly to expose aggregate evenly.
- Local suppliers: Certain exposed blends may cost more due to transport or availability.
The team from Melbourne Concrete Driveways notes, “In some suburbs, clients prefer a specific stone look – we often source materials from local quarries to match their vision, even if it slightly increases the cost.”
Is an Exposed Aggregate Driveway Worth the Investment?
Yes – in most cases, it is. You get long-term durability, excellent visual return, and low ongoing maintenance. For properties aiming to stand out or sell above market value, this surface provides an edge.
However, if you’re on a tight budget or prefer a softer feel underfoot, plain concrete may suffice. The initial outlay is higher, but the curbside transformation can be dramatic.
