Located approximately 55 km south of Melbourne CBD, Somerville is a growing township on the Peninsula with a village atmosphere and strong family community. As part of the Mornington Peninsula region, Somerville benefits from strong local amenities and established infrastructure. Exposed aggregate is well-suited to Somerville’s mix of property styles, offering a finish that complements both older homes and newer builds.
Exposed aggregate concrete delivers a durable, slip-resistant finish that reveals natural stone textures beneath the cement surface—combining structural performance with decorative appeal for Melbourne properties.
Nupave specialises in exposed aggregate installation and restoration across Melbourne, the Mornington Peninsula, Bass Coast, Phillip Island, and surrounding regions. Our team handles everything from new driveways and pool surrounds to commercial flooring projects, using locally sourced aggregates and installation methods that meet Australian Standards.
Why Exposed Aggregate Concrete is Perfect for Melbourne Properties
Low Maintenance Requirements When Properly Sealed
Exposed aggregate concrete requires relatively low maintenance compared to many alternative exterior materials when the surface is properly sealed after installation. The primary ongoing requirement is periodic resealing—typically every two to three years, though high-traffic areas or surfaces with significant UV exposure may benefit from more frequent attention. This resealing protects against staining, helps resist water penetration, and maintains the visual enhancement that quality sealers provide.
General cleaning involves hosing down the surface and occasional washing with mild detergent to remove accumulated dirt, leaves, and other contaminants. Pressure washing can be used but should be applied at lower pressure settings and appropriate angles to avoid dislodging aggregate or damaging the sealer layer. Oil stains and spills should be cleaned promptly to prevent absorption into the concrete matrix.
Compared to pavers—which require joint sand replenishment, weed control, and periodic realignment—exposed aggregate presents fewer maintenance tasks. The continuous surface eliminates joints where weeds establish and where ants create sand displacement. Compared to timber decking or other materials requiring annual treatments, exposed aggregate offers a more straightforward maintenance schedule focused primarily on cleaning and periodic sealing.
At Nupave, our commitment to our customers doesn’t end once the job is complete. We understand that life gets busy, and important maintenance like resealing can easily be overlooked. That’s why we’ve created a simple care plan system, where your project is added to our register and you receive timely reminders when your concrete is due for resealing. There’s no cost for this service—it’s simply part of how we look after our clients and help protect their investment long-term. By staying on top of maintenance, your surface continues to perform and look its best for years to come, without you having to keep track of it yourself.
What Exposed Aggregate Concrete Is and How It’s Created
Exposed aggregate concrete is a decorative finish created by removing the top layer of cement to reveal the natural stone within the mix. This produces a textured, visually distinctive surface, with the chosen aggregate—such as basalt, granite, or river pebbles—defining the overall look. The finish is achieved through a controlled process that exposes the stone at the right time, resulting in a durable surface that combines natural appearance with long-term performance.
Durability Compared to Plain Concrete and Other Decorative Options
Exposed aggregate concrete offers structural durability that matches or exceeds plain concrete while providing superior visual longevity. When properly installed with appropriate strength grades—commonly N32 or N40 for driveways and high-traffic areas—exposed aggregate surfaces in Melbourne can last 25 to 35 years or more. Some installations under optimal conditions reach 40 years of service life, particularly when combined with regular sealing and proper drainage management.
The durability advantage over plain concrete becomes apparent in how the surfaces age. Plain concrete tends to show tyre marks, surface staining, and colour fading more prominently over time. The cement paste layer that forms the visible surface of plain concrete is more susceptible to UV degradation and wear. Exposed aggregate, by contrast, places natural stone as the primary wearing surface. Hard aggregates like basalt and granite resist abrasion and weathering far better than cement paste alone, maintaining their appearance even under vehicle traffic and Melbourne’s variable weather conditions.
Compared to other decorative concrete options such as stamped concrete or coloured concrete, exposed aggregate typically requires less cosmetic maintenance. Stamped concrete may need periodic recolouring or pattern repair as the surface wears. Pavers require joint maintenance and can shift over time, allowing weed growth between units. Exposed aggregate presents a monolithic surface without joints, reducing ongoing maintenance demands while providing a naturally durable wearing course.
Slip-Resistant Texture Ideal for Melbourne’s Variable Weather
Exposed aggregate provides natural slip resistance thanks to its textured surface, making it ideal for Melbourne’s wet and variable conditions. The exposed stones create added grip underfoot and under tyres, which is especially beneficial for driveways, pathways, and pool surrounds. When installed correctly, it offers a balance of safety and comfort suited to both everyday use and high-moisture areas.
Our Exposed Aggregate Services
Residential Exposed Aggregate
We provide custom exposed aggregate installations for residential properties across Melbourne, with each project tailored to suit the home’s style, usage, and site conditions. Driveways, pathways, patios, and pool surrounds are designed with the right aggregate selection, reinforcement, and drainage to ensure both visual appeal and long-term performance. Where suitable, we also assess existing concrete for resurfacing options, offering a cost-effective alternative to full replacement when the slab is structurally sound.
Commercial Exposed Aggregate Flooring
Commercial projects demand attention to compliance requirements, traffic loads, and design integration with broader site development. Office building entrances and corporate walkways benefit from exposed aggregate’s professional appearance and minimal maintenance requirements, reducing ongoing management costs while enhancing property presentation.
Retail and hospitality applications utilise exposed aggregate for outdoor dining areas, shopping centre walkways, and entrance features. The durability handles high pedestrian volumes while the range of available finishes allows design coordination with overall site aesthetics.
Public space installations require compliance with relevant Australian Standards including AS 1379 for concrete specification and supply. Council projects often specify particular aggregate types and exposure depths to match existing streetscape materials—City of Melbourne specifications, for example, require N40 strength grade with 14mm crushed basalt for exposed aggregate kerbs, matching the bluestone character of established streetscapes.
Is New Concrete Always Necessary?
Before investing in a brand new exposed aggregate driveway, it’s important to understand whether your existing concrete can be improved rather than replaced. Many surfaces that look beyond repair can often be transformed using alternative methods, avoiding the need for costly excavation. A professional inspection can give you a clear answer and help you avoid unnecessary expenses while still achieving a high-end result.
If your concrete can be repaired or resurfaced, we’ll tell you—there’s no benefit to you replacing it unnecessarily.
Our Professional Installation Process
Step 1: Site Assessment and Design
Every exposed aggregate project begins with onsite evaluation of existing conditions. This assessment covers soil characteristics—particularly important in Melbourne where reactive clay soils are common and require specific preparation approaches. Drainage requirements, access constraints, existing services, and slope conditions inform both design and construction planning.
Aggregate selection occurs during this consultation phase. We present samples of available aggregate types and blends, discussing how different options suit your property’s architecture, landscaping, and intended use. Colour coordination with house materials, preferred texture levels, and budget considerations guide the final aggregate specification.
Step 2: Preparation and Base Work
Proper preparation determines long-term performance. Excavation removes existing material to required depth, accounting for base layer thickness, concrete slab depth, and finished surface level relative to surrounding elements. In reactive soil areas, additional depth or moisture management measures may be incorporated.
Base preparation involves placing and compacting crushed rock to create a stable foundation. Compaction achieves approximately 95% Modified Proctor density to prevent future settlement. Reinforcement installation—typically steel mesh for residential applications or bar reinforcement for heavy-duty commercial use—provides tensile strength to resist cracking under load and thermal movement.
Formwork establishes edge profiles and levels, with careful attention to drainage falls directing water away from buildings and towards appropriate discharge points. Control joint locations are planned during this phase, positioning cuts to accommodate shrinkage cracking at predetermined locations rather than allowing random crack development.
Step 3: Concrete Pour and Finishing
Concrete placement requires coordination with batch plant delivery schedules and site readiness. The mix specification—strength grade, aggregate size, slump, and any admixtures—follows AS 1379 requirements appropriate to the project. Common specifications include N32 or N40 grades with 20mm maximum aggregate size for residential driveways.
Placement, spreading, and initial levelling occur immediately following delivery. Bull float and finishing tools work the surface to achieve correct levels while consolidating the concrete without segregating the aggregate. The timing of subsequent operations depends on ambient temperature, humidity, and mix characteristics.
Surface retarder application must occur within specific time windows—typically when the concrete has firmed sufficiently to walk on but before the surface cement paste hardens fully. This retarder delays paste set at the surface while allowing the underlying concrete to continue curing, creating the differential hardening that enables controlled aggregate exposure.
Step 4: Cleaning, Sealing and Protection
The washing process removes retarder-affected cement paste to reveal the aggregate beneath. Timing is critical—typically 4 to 24 hours after placement depending on conditions and retarder type. Pressure washing at appropriate settings removes the paste layer without dislodging aggregate or creating uneven exposure.
Once washed and allowed to dry, the surface receives protective sealer application. Quality sealers penetrate the concrete surface and coat the exposed aggregate, protecting against oil stains, water absorption, and UV effects while enhancing the natural stone colours. Full cure of both concrete and sealer typically requires several days before the surface can accept vehicle traffic.
Ongoing protection depends on periodic resealing—typically every two to three years—and prompt attention to any stains or spills that could penetrate the sealer layer.
