What This Page Covers
Exposed aggregate concrete is a popular choice for driveways, patios, and outdoor areas thanks to its durability, slip resistance, and natural stone finish. If you're planning a project, understanding what influences the cost can help you budget more effectively. This guide explains the key factors that affect pricing and how Boral supports you with regionally tailored, high-quality mixes.
What Affects the Cost of Exposed Aggregate Concrete?
1. Aggregate Type and Appearance
The size, colour, and source of the aggregate influence the price. Premium stones or decorative blends may cost more but offer greater visual impact. Locally sourced aggregates are often more cost-effective and environmentally friendly.
If you choose to add colour to your mix using Boral’s Colori® range, this will increase the overall cost slightly. However, the benefit is significant: Colori® allows for precise colour matching to your home’s exterior, landscaping, or architectural features, giving you greater creative control. It also opens up design possibilities beyond the natural stone palette, helping your project stand out while maintaining the durability of exposed aggregate.
2. Project Size and Design Complexity
Larger areas may benefit from economies of scale, but intricate designs, curves, or borders can increase labour and material costs.
3. Site Conditions and Preparation
Uneven terrain, poor drainage, or the need for excavation will add to the overall cost. A well-prepared site ensures better performance and longevity.
4. Location and Regional Pricing
Costs vary across Australia due to transport, labour rates, and aggregate availability. Boral’s exposed aggregate mixes use locally sourced quarry materials wherever possible. This not only helps keep transport costs down, but also reduces environmental impact and supports regional suppliers. It’s why our colour ranges vary by location - each mix reflects the natural stone and sand tones of its region, creating a sense of place and visual harmony with local surroundings.
5. Labour and Installation
Installation is typically handled by professional concreters. Their rates depend on experience, location, and project complexity. Boral supplies the concrete but does not provide installation services. Your local Boral sales representative may be able to recommend a suitable concreter.
6. Additional Finishes
Sealing, polishing, or decorative edging can enhance the look and durability of your surface but should be factored into your budget.
Is Exposed Aggregate Concrete More Expensive than Conventional Concrete?
Compared to conventional concrete, exposed aggregate typically comes at a higher upfront cost due to the decorative finish and additional processing. However, it offers superior aesthetics and surface performance.
If you’re looking for a more sustainable option, Boral’s ENVISIA® low-carbon concrete is available in both exposed aggregate and standard finishes, allowing you to reduce your project’s carbon footprint without compromising on quality or appearance.
Why Exposed Aggregate Offers Long-Term Value
While the upfront cost of exposed aggregate concrete may be higher than plain concrete, its long-term value makes it a smart investment for outdoor surfaces. The finish is exceptionally durable, standing up to heavy vehicle traffic, footfall, and Australia’s varied climate conditions. With proper sealing, it resists stains, erosion, and surface wear, reducing the need for frequent repairs or resurfacing.
Its textured surface also provides natural slip resistance, making it a safer choice for driveways, paths, and pool surrounds. This is especially important in areas prone to rain or where children and older adults are present.
Beyond performance, exposed aggregate enhances the visual appeal of your property. The natural stone finish adds depth and character, and with a wide range of colours and aggregate types available, it can be tailored to suit both modern and traditional designs. This aesthetic flexibility can increase curb appeal and even boost property value over time.
How to Budget for Your Project
Planning your budget for an exposed aggregate concrete project starts with understanding the variables. Begin by requesting quotes from multiple concreters. Installation costs can vary significantly depending on the contractor’s experience, your location, and the complexity of the job.
Next, speak with a supplier like Boral to explore mix options that align with your design goals and budget. Our team can help you select aggregates and colours that offer the right balance of cost, performance, and visual appeal.
It’s also important to account for site-specific factors. Access to the site, slope, drainage, and soil conditions can all affect preparation costs. A site that requires excavation, levelling, or additional base materials will increase the overall spend.
Finally, don’t forget to include finishing costs in your budget. Sealing is essential for protecting the surface and maintaining its appearance and may need to be reapplied every few years depending on use and exposure.
