Exposed Aggregate Concrete Cost Explained 2025

Exposed aggregate concrete is one of the most popular decorative concrete finishes used across Perth for driveways, paths, patios and pool surrounds. Its textured appearance, combined with durability and low maintenance, makes it a smart long-term investment. But how much does exposed aggregate concrete really cost in Perth?

This cost guide breaks down the current exposed aggregate concrete prices, installation factors, cost-saving tips and how it compares to other concrete options, so you can budget effectively for your next project.

What is Exposed Aggregate Concrete?

Exposed aggregate concrete is a decorative concrete finish where the top layer of cement is removed to reveal the natural stones (aggregates) beneath. These aggregate materials may include crushed stone, gravel, or specially selected coloured stones that offer aesthetic appeal and traction.

Unlike plain concrete or standard concrete finishes, exposed aggregate provides a more architectural concrete appearance. It is ideal for outdoor surfaces such as concrete driveways, pool decks, and patios thanks to its slip resistance and design flexibility.

Average Cost of Exposed Aggregate in Perth

The cost of exposed aggregate concrete in Perth typically ranges from $100 to $150 per square metre. This price includes material costs and labour costs for having the concrete professionally installed. Labour costs are a significant component of the total cost for installing exposed aggregate concrete. It can vary depending on the concrete supplier, site conditions, and the type of aggregate chosen.

For raw concrete, the price per cubic metre generally falls between $200 and $350, depending on the concrete mix and grade.

Here’s a quick cost reference:

Factors That Affect the Cost of Exposed Aggregate Concrete

The final price of your exposed aggregate project can vary depending on several factors:

1. Size of the Area

Larger areas often benefit from lower rates per square metre, while small concrete slabs may incur a minimum charge.

2. Type of Aggregate

Premium stones and decorative blends increase material costs. Common aggregates are more affordable.

3. Concrete Grade

The grading system, measured in megapascals (MPa), determines the strength. Normal class concrete (20–25 MPa) is typical for driveways. Special class concrete costs more but offers added durability.

4. Site Access and Preparation

Tight access, sloping land or the need to remove existing concrete will increase excavation costs and time. Excavation and levelling of the site are essential steps that can affect overall project costs.

5. Labour and Complexity

Intricate shapes, curved edges, or complementary colours require specialised equipment and skilled labour, raising the overall cost. The complexity of the installation contributes to the labour costs for exposed aggregate concrete.

6. Drainage and Slope Management

Projects that require drainage installation or adjustment will cost more, especially if regulations dictate engineered solutions.

7. Finish and Sealing

A surface retarder is used to expose the aggregate. The concrete finish may also include a sealer to improve appearance and longevity, adding to the budget.

8. Project Type

Pool surrounds, pathways, and patios have different labour intensities and finishing requirements compared to a standard concrete driveway.

Cost Comparison: Exposed Aggregate vs Standard Concrete

Exposed aggregate concrete offers more curb appeal, texture and long-term value than plain or traditional concrete, although at a higher upfront cost. Standard concrete is typically cheaper than exposed aggregate concrete.

Benefits of Exposed Aggregate Concrete

• Durable in all conditions: Suitable for heavy traffic, harsh weather, and long-term use
• Aesthetic flexibility: Choose contrasting or complementary colours to match your home
• Slip-resistant texture: Safer for pool decks and outdoor surfaces
• Low maintenance: Resealing every few years is usually all that is required
• Long lifespan: With proper care, exposed concrete can last for decades
• Boosts property value: Attractive driveways and patios improve resale appeal

• Exposed aggregate cost per m²: $120
• Total base cost: $9,600
• Additional costs (site prep, drainage, sealing): $1,400
• Estimated total project cost: $11,000

If existing concrete needs to be removed, this could add another $1,000–$2,000 to the final price.
