What is Exposed Aggregate Concrete?
Exposed aggregate concrete starts as regular concrete mixed with carefully selected stones, then gets treated with surface retarders that slow the curing of the top layer. After the concrete sets, we wash and brush away the surface cement, revealing the beautiful aggregates underneath. This process creates a textured, non-slip surface that showcases natural stone colours and patterns.
Natural Stone Aggregate Varieties
River Pebbles
Smooth, rounded stones in natural earth tones create classic, timeless finishes perfect for traditional and contemporary homes. These water-worn aggregates offer excellent slip resistance and comfortable barefoot surfaces. Available in cream, grey, brown, and mixed colour combinations that complement Australian landscapes beautifully while providing long-lasting durability in all weather conditions.
Basalt Aggregates
Dark, dense stones create modern, sophisticated looks that complement contemporary architecture and landscaping. Basalt’s volcanic origin provides exceptional strength and fade-resistant colour. These premium aggregates offer sleek appearances in charcoal and black tones while delivering superior performance in high-traffic areas and extreme weather conditions.
Crushed Granite
Available in grey, pink, and white variations, granite aggregates provide sophisticated, refined appearances with excellent durability. The angular stone fragments create superior traction and modern visual appeal. Granite’s natural sparkle adds elegance to driveways and patios while resisting weathering and maintaining colour integrity through decades of exposure.
Comprehensive Design Services
Site assessment and design planning help determine optimal aggregate selections and layout patterns. We provide physical aggregate samples and colour visualisation tools to help you make informed decisions about your project’s appearance.
Architectural Integration
Exposed aggregate finishes complement various architectural styles from modern contemporary to traditional heritage homes. We coordinate with existing landscape features and outdoor living areas to create cohesive design themes.
Professional Installation Process
Investment Value
Return on Investment
Exposed aggregate installations significantly improve property values through enhanced curb appeal and premium finishes. The durable surfaces provide long-term value with low maintenance costs and timeless beauty that doesn’t date.
Value Comparison
Exposed aggregate offers superior durability compared to plain concrete, lower maintenance than pavers, and better value than natural stone alternatives. The long-term cost-effectiveness makes it an excellent investment choice.
Maintenance and Care
Exposed aggregate requires minimal ongoing care for decades of beautiful appearance. Regular cleaning with water maintains surface quality while natural stone aggregates resist fading and weathering.
Maintenance includes:
- Water and mild detergent cleaning
- Occasional pressure washing for a deep clean
- Joint sealing when applicable
- Professional restoration services are available
- Long-term performance with minimal upkeep
Absolutely. Exposed aggregate offers climate-resistant durability, excellent slip resistance, low maintenance requirements, and enhanced property value. For Canberra homeowners seeking both aesthetic appeal and practical functionality, it’s an investment that delivers long-term benefits.
While pebblecrete offers similar durability benefits, exposed aggregate delivers a more refined appearance. Most Canberra homeowners prefer exposed aggregate for its superior performance and more sophisticated aesthetic in our local climate conditions.
When properly installed by professional contractors, exposed aggregate concrete withstands Canberra’s extreme temperature variations for decades. Its engineered durability ensures it resists cracking and deterioration that often affects standard concrete surfaces.
Standard concrete offers a lower-cost option with less visual appeal. Stamped concrete provides more design options but at a higher price. Pebblecrete delivers similar benefits but with a different aesthetic finish. Each has different maintenance requirements and durability characteristics.
Exposed aggregate requires only occasional cleaning and sealing every few years to maintain its appearance and protective qualities. This low maintenance requirement makes it particularly appealing to busy Canberra homeowners.
No. The textured surface of exposed aggregate provides excellent slip resistance during frost or rainy periods. This makes it a particularly safe option for pool surrounds and outdoor spaces in Canberra’s variable climate.
While technically possible, I don’t recommend DIY-exposed aggregate in Canberra due to our specific climate challenges. The critical timing required for exposing the aggregate is challenging with our rapid temperature changes and seasonal moisture variations.
Yes, but with limitations. Canberra’s extreme temperature fluctuations make overlay bonding more challenging. The existing concrete must be structurally sound with no major cracking, which is uncommon in older Canberra properties due to our reactive clay soils.
Earthy tones with subtle blue or grey undertones beautifully complement Canberra’s native landscape. Warm sandstone blends work wonderfully for heritage areas like Yarralumla or Red Hill, while cooler grey tones suit modern homes in Gungahlin and Kingston.
