What is Exposed Aggregate Concrete?

Exposed aggregate concrete begins like any other concrete: it is poured and allowed to set. The distinctiveness arises from the surface treatment applied before the concrete fully cures.

The Process

• After pouring, contractors remove the top layer of cement paste.
• This is achieved by washing, brushing or applying a surface retarder or chemical deactivator.
• Removal reveals the aggregates underneath — these can be natural small stones, pebbles, coloured glass pieces, or crushed rock.
• The aggregates remain firmly embedded, creating a strong, textured surface.

This technique is sometimes called washed concrete because of the water washing step used to expose the aggregate surface. Learn more here.

Typical Materials Used

• Aggregates vary in size from fine pebbles to larger stones.
• Many mixes use locally sourced stones and pebbles found across Australia to complement the natural landscape.
• Coloured glass or other decorative aggregates may be added for unique finishes.

Exposed Aggregate Mixes Australia Offers

• Size Variations: Fine pea gravel up to larger river stones or crushed granite.
• Colour Choices: Natural tans, greys, reds and blacks, often customised to integrate with house exteriors or gardens.
• Texture Options: Smooth, slightly rough, or highly textured surfaces depending on aggregate type and exposure level.

Homeowners and designers can work with suppliers to create mixes that harmonise with both modern and traditional architectural styles, as well as natural surroundings found in the Mornington Peninsula and elsewhere.

This customisation flexibility means exposed aggregate driveway Mornington Peninsula projects often feature blends that echo the coastal environment or native bushland.

Benefits of Exposed Aggregate Concrete

Choosing exposed aggregate concrete offers several key benefits, especially for outdoor surfaces like driveways on the Mornington Peninsula and throughout Australia.

Durability

• Exposed aggregate concrete is exceptionally tough, able to withstand Australia’s harsh weather extremes, including strong UV, rain, and temperature changes.
• It tolerates heavy vehicular traffic and physical wear better than many other decorative finishes.
• Its robust surface resists cracking and surface degradation, providing long-term value.

Slip Resistance

• The texture created by exposed aggregates offers natural slip resistance.
• This makes it safer for driveways, pool surrounds, garden paths, and entryways, reducing slip risks in wet conditions.
• It is an excellent choice for families, seniors, and areas prone to rain. Learn more.

Visual Appeal and Customisation

• Versatile aesthetic options allow customised aggregate sizes and colours.
• Homeowners can choose from rustic natural textures to bold, decorative glass or coloured stone mixes.
• This flexibility supports creative driveway designs that suit various architectural styles.
• The variable texture adds depth and visual interest, enhancing curb appeal.

Low Maintenance

• Periodic cleaning with a broom or low-pressure water wash removes dirt, moss, and debris.
• Occasional resealing preserves the surface’s vibrancy, protects against wear, and maintains slip resistance.
• Unlike plain concrete, which can stain or dull, exposed aggregate maintains texture and colour longer.

These combined benefits make exposed aggregate concrete highly practical and visually attractive for Australian homeowners looking for durable, customisable driveways and outdoor spaces. More details.

Exposed Aggregate vs Plain Concrete: A Detailed Comparison

Feature	Exposed Aggregate Concrete	Plain Concrete
Aesthetics	Decorative, textured, varied aggregates	Smooth, uniform, basic appearance
Slip resistance	High – natural texture reduces slippage	Moderate – smooth surface may be slippery when wet
Durability	Excellent – rugged surface suited for outdoors	Excellent – but less textured
Cost	Higher – approx. $2–3 more per square metre	Lower – simpler materials and labour
Installation	More complex – requires surface exposure steps	Simpler pour and finish
Maintenance	Low – requires periodic resealing	Low – occasional cleaning
Applications	Ideal for driveways, patios, paths, pools	Common in garages, basements, basic paths

Which Option is Best?

• Exposed aggregate concrete is suited for areas prioritising style, safety (slip resistance), and outdoor endurance.
• Plain concrete is economical and functional for garages, crawl spaces, or hidden areas where aesthetic is less important.
• For high-traffic decorative outdoor surfaces, exposed aggregate’s unique texture and design flexibility often outweigh the slightly higher exposed aggregate driveway cost.

Cost Considerations for Exposed Aggregate Driveways

When budgeting for an exposed aggregate driveway, several factors influence the final price.

Key Cost Factors

• Labour: Skilled contractors charge more due to the precise timing and techniques needed to expose aggregates properly. Additional treatment and sealing work add to overall costs.
• Location: Regional differences in supplier availability and labour rates can impact price. Remote or less accessible areas may see higher costs due to transport fees.

Typical Price Range

On average, expect $100–$150 per square metre for a standard exposed aggregate driveway installation in Australia. Complex designs, high-end mixes, or unique aggregate choices push costs toward the upper end of the range.

Budgeting Tips

• Get multiple quotes from local contractors to compare pricing.
