How Much Does Exposed Aggregate Cost?

Exposed aggregate costs around $140 to $220 per square metre. This pricing varies based on factors such as location, the complexity of the job, and the materials chosen. Additional considerations, including site preparation and design requirements, can influence the final price.

This blog explores cost-driving factors, city-specific pricing, and how to calculate expenses for exposed aggregate. Whether you’re seeking the best concrete for your project or looking to understand regional differences, this guide breaks it all down for you.

The factors influencing the cost of exposed aggregate are material costs, labour costs, project size, and site preparation:

The type of aggregate chosen plays a major role in pricing. Decorative options, such as coloured stones or glass, tend to increase expenses. Cement quality and other additives also impact the overall concreting cost.

The skill level required for exposed aggregate affects labour rates. Complex patterns or finishes may demand more time and expertise, leading to higher costs. Additionally, travel distances for contractors can add to the final bill.

Smaller jobs often incur higher per-metre rates due to setup and transport expenses. Larger projects typically benefit from economies of scale. Intricate designs or custom requirements may further influence costs.

Sloping or uneven ground often requires extra preparation, increasing costs. Difficult-to-reach sites may involve additional equipment or time. Clean and accessible locations help reduce labour and setup delays.

Estimating the cost of exposed aggregate involves considering the area to be covered and the per-square-metre rate. This straightforward process helps homeowners budget effectively for their concreting projects.

The formula for calculating the cost is:

Total Cost = Area (m²) × Rate per m²

Example:

If a driveway or concrete slab measures 30 square metres and the rate is $130 per square metre, the calculation would be: 30 m² × $130/m² = $3,900

Additional costs, such as site preparation or decorative finishes, should be factored in when planning your budget. Always consult contractors for precise estimates tailored to your project.
