Understanding Exposed Aggregate Concrete
Exposed aggregate concrete is more than a simple construction material—it’s a design element that transforms ordinary surfaces into distinctive visual features. This finish is achieved by removing the top layer of cement to reveal an array of embedded pebbles, rocks, and sand, offering both texture and colour that can elevate the aesthetics of any outdoor area.
Definition, Composition, and Aesthetic Appeal
Exposed aggregate concrete is produced by pouring a standard concrete mix and then treating its surface to expose the natural aggregates within. These materials, ranging from small stones and pebbles to sand, are carefully selected to provide contrasting colours and varied textures, contributing to a mosaic-like finish that enhances the overall look of a surface. This decorative approach not only creates a unique visual appeal but also provides an organic, natural feel that blends well with both modern and traditional environments.

Beyond its striking appearance, exposed aggregate concrete is highly regarded for its practicality. The presence of textured aggregates makes the surface naturally slip-resistant, an important feature for high-traffic areas such as driveways, pool surrounds, and alfresco areas. In addition, this finish is appreciated for its durability and low maintenance requirements. Homeowners and builders alike favour exposed aggregate for applications where both beauty and functionality are critical. Common uses include driveways, alfresco areas, and pool enveloping surfaces—each benefiting from the enhanced traction and enduring performance that this material offers. Whether you are upgrading an outdoor space for safety or style, the benefits of exposed aggregate concrete extend far beyond mere aesthetics.
How Exposed Aggregate is Crafted: The Application Process
Creating an exposed aggregate finish is a multi-step process that transforms ordinary concrete into a decorative surface with superior texture and visual appeal. The entire procedure is carefully managed to ensure that both the aesthetics and performance of the finished surface meet high standards, making it an ideal choice for driveways, pool surrounds, and alfresco areas.
Step-by-Step Process Overview
The process begins with a standard concrete pour, followed by key steps that progressively reveal the natural beauty of the embedded aggregates:
- First, the concrete is poured into the prepared area and allowed to set until it reaches a semi-hardened state.
- Once the concrete is partially cured, contractors employ techniques such as washing or gentle brushing to remove the top layer of cement, which exposes the aggregates lying beneath.
- This exposure process is carefully controlled to ensure that the aggregates—whether pebbles, small stones, or sand—are evenly revealed across the surface.
- To complete the procedure, a quality sealant is applied to protect the now-exposed aggregates, ensuring that the finish remains durable and resistant to the everyday rigours of outdoor conditions.
Special Techniques and Equipment Used
Precision and consistency are paramount in achieving a flawless exposed aggregate finish. Skilled tradespeople use specialised tools and methods to deliver a superior result:
- Specialised Equipment: Tools such as mechanical lathes, high-pressure washers, and custom brushes are used to precisely remove the top cement layer without damaging the underlying materials.
- Chemical and Surface Treatments: In some cases, a chemical surface retardant is applied to help control the curing process. This ensures that the aggregates are exposed uniformly and remain well-integrated into the concrete matrix.
- Final Sealing Process: The sealing stage involves applying a high-quality sealant that enhances colour and texture while providing long-term protection. This step not only locks in the aesthetics but also contributes to the surface’s slip-resistant and durable properties.
Through these meticulous techniques and the use of specialised equipment, the process of crafting exposed aggregate concrete transforms a functional material into a design feature that adds enduring value and appeal to any outdoor space.
Major Cost Factors That Influence Exposed Aggregate Pricing
Selecting exposed aggregate concrete isn’t just about the look—it’s also an investment that reflects several detailed cost factors.

Premium aggregates sourced locally or imported for their distinctive colour and durability often come at a higher cost. It’s not just about aesthetics—the quality of these materials plays a part in ensuring that the finished surface is robust and long-lasting. Homeowners who prioritise both durability and visual appeal may find that investing in higher-grade aggregates is well worth the extra expense.
Design Complexity and Surface Area Considerations
The overall design and size of the project also contribute to the variation in costs. Customised designs, intricate patterns, or surfaces with irregular shapes will typically demand more time and precision during installation. For instance, projects that incorporate steep slopes or extensive areas require careful planning and execution to achieve an even finish. Conversely, larger projects may benefit from economies of scale, but this is balanced against the challenges of maintaining consistency across a greater surface area. Each additional design element or irregularity can add layers of complexity—thereby increasing both material and labour costs.
Understanding these cost factors is key to making informed decisions. By recognising how labour intensity, material quality, and design complexity influence the final price, you can better plan and budget for an exposed aggregate project that delivers both on beauty and longevity.
Average Pricing Breakdown per Square Metre and per Cubic Metre
When making plans for an exposed aggregate project, it’s crucial to establish a realistic budget based on average pricing. Understanding the breakdown by square metre and cubic metre helps ensure you’re prepared for both material and labour costs, as well as any regional variations that might apply.
Typical Prices and Ranges in Australia
Exposed aggregate concrete generally carries a price tag in the region of approximately $90 to $150 per square metre. This range takes into account various factors such as the chosen aggregate type, project design, and the complexity of installation. For instance, a simple driveway might lean toward the lower end of the scale, while a customised alfresco area or extensive pool surround could push costs towards the higher end.
When dealing with larger projects, prices per square metre may benefit from economies of scale; however, irregular shapes or challenging site conditions can also elevate overall costs. In addition to surface pricing, ordering concrete directly from suppliers is often calculated on a per cubic metre basis, with typical costs ranging, for example, from $200 to $350 per cubic metre depending on concrete strength and mix requirements. These figures provide a useful benchmark to compare bids and ensure transparency when obtaining quotes.
Price Comparison with Standard Concrete Finishes
It’s worth noting that exposed aggregate finishes are generally more expensive than standard plain or coloured concrete. The added cost stems from the extra labour and specialised techniques involved. Whereas a standard concrete installation might cost in the range of $60 to $85 per square metre, exposing the aggregates typically ups the price by around $30 or more per square metre. In return, you’re rewarded with enhanced aesthetic appeal, improved slip resistance, and a superior texture that standard finishes lack.
For many homeowners, this additional investment is justified by the long-term benefits of durability and the distinctive visual impact that exposed aggregate surfaces offer.
