Nupave recommended external concrete specification — Oakleigh East
Group 1 — Bayside / Sand Belt — Brighton Group Sands
Concrete: 32 MPa (all exposed aggregate)
Indicative regional ground conditions
Oakleigh East sits on the Bayside / Sand Belt, where the natural profile is dominated by free-draining Brighton Group sands. Regional ground conditions are generally stable and low-reactivity, though loose sand pockets can require additional compaction. The actual AS 2870 site classification for any individual property can only be established through a site-specific geotechnical investigation, taking into account soil profile, fill, moisture conditions and vegetation.
Regional ground movement (indicative, AS 2870)
Ground of this type may exhibit generally low seasonal surface movement (indicatively under 20 mm). This is a regional indicator only — actual movement at a given address depends on soil profile, moisture history and tree influence.
| Application | Slab thickness | Sub-base | Reinforcement |
|---|---|---|---|
| Path / foot traffic | 75–100 mm | 50–75 mm compacted crushed rock | SL72 |
| Driveway (cars up to 3 t) | 100 mm | 75–100 mm compacted crushed rock | SL72–SL82 |
| Occasional truck (3–10 t) | 125–150 mm | 100 mm compacted crushed rock | SL82 or rebar |
Nupave standard specification for typical conditions of this soil group — subject to site-specific assessment. Not a design substitute for a project engineer’s report where one is required.
| Saw-cut / control joint spacing (100 mm slab) | |
|---|---|
| Spacing between cuts | 2.7 m – 3.0 m (standard spacing) |
| Cut depth & timing | At least 25 mm on a 100 mm slab (¼ slab thickness). Saw-cut as soon as the concrete can be cut without excessive ravelling — timing will vary with the mix, weather and saw type. A quick trial cut on a low-visibility edge or offcut is best practice before committing to the full grid. |
| What joints do | Closer joint spacing and properly proportioned panels encourage drying-shrinkage and thermal movement to occur at planned locations. Control joints reduce the risk of random cracking; they do not prevent cracking caused by inadequate support or differential ground movement. |
| Panel shape | Keep panels close to square (length ≤ 1.5× width). Long, narrow panels are more prone to random cracking regardless of joint spacing. |
Concrete grade
All Nupave exposed aggregate is poured at N32 as standard, regardless of soil group. The aggregate-exposure process removes the top cement paste layer, so the slab benefits from the higher compressive strength, improved durability and better abrasion resistance of N32. For non-exposed external concrete work, Nupave specifies N25 or N32 depending on application, anticipated loading, exposure conditions, selected finish and any site-specific engineering requirements. Concrete strength alone does not compensate for inadequate subgrade preparation, drainage or ground movement — it is one element within a properly detailed slab system.
Slip layer (poly membrane)
A polyethylene separation or slip membrane may be considered where required by the slab design or site conditions. It can reduce friction between the slab and compacted base during concrete shrinkage, but does not prevent settlement, heave or other vertical ground movement. Where a project engineer or geotechnical report specifies membrane use, that specification takes precedence.
Sub-base — why it’s a key part of the quote
Correct excavation, drainage, and a uniformly compacted crushed-rock base significantly reduce settlement and provide consistent support under the slab. It adds cost — both in laying and compacting the base, and in the extra excavation and spoil-removal that comes with the deeper dig — but that preparation is what a slab needs to perform over the long term. The preparation actually required may vary where uncontrolled fill, soft areas or unsuitable material are encountered on the specific site.
Curing coat
Concrete requires curing to develop its full design strength and durability. A liquid curing coat is applied after finishing, once bleed water has disappeared and in accordance with the manufacturer's requirements. It seals moisture into the concrete so hydration continues over the first 7 days — when the concrete's real strength develops. In summer, hot dry weather removes surface moisture quickly, so curing coat is essential to prevent surface crazing and reduced final strength. In winter, lower temperatures slow hydration, so curing is still required to reach design strength — the curing coat is still applied, and duration may need to be extended. Nupave applies curing coat as standard on all pours year-round.
Microfibres in concrete mix Optional add-on
What fibres actually do. Microfibres (polypropylene) get mixed through the whole pour and mainly control plastic shrinkage cracking in the first 24 hours, plus improve abrasion / impact resistance — they don’t add real structural tensile capacity. Macrofibres (heavier synthetic or steel) go further, adding post-crack toughness and some flexural strength.
Genuine benefit as an add-on: reduces fine / hairline shrinkage cracking and improves durability on any slab, sand or clay.
Should NOT replace mesh on soft or highly plastic clay soils: fibres provide no real resistance to the larger, ground-movement-driven cracks that mesh or rebar controls.
Salt / coastal exposure
Suburbs within roughly 1 km of Port Phillip Bay are subject to salt spray. Nupave uses B1 exposure classification (N32 minimum) and increases concrete cover to reinforcement on foreshore-proximate work to protect against saline-induced corrosion.
Important: This is Nupave’s enhanced standard specification for typical conditions in this suburb group, and is presented as a general reference. It is not a site-specific engineering design. Actual specifications for any individual property may vary based on site conditions, uncontrolled fill, tree influence, drainage, or requirements identified in a site-specific geotechnical or engineer’s report. Where an engineered design has been prepared for the site, that design takes precedence.

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 clients extends well beyond the completion of your project. We understand that ongoing maintenance is essential, but also easily overlooked in busy day-to-day life. That’s why every project is added to our exclusive care register, allowing us to provide timely reminders when your concrete is due for resealing. This service is provided at no cost as part of our standard — not as an add-on — ensuring your investment remains protected and continues to perform at its best. It’s a simple, proactive approach designed to give you long-term results without the need to manage it yourself.
What Exposed Aggregate Concrete Is and How It’s Created
Exposed aggregate concrete is a decorative concrete finish created by removing the top layer of cement paste to reveal the natural stone, pebbles, and gravel embedded within the mix. This process produces a textured, visually distinctive surface that differs significantly from plain finished concrete. The aggregate—whether basalt, granite, river pebbles, or crushed quartz—becomes the dominant visual element, creating surfaces that range from subtle stone exposure to pronounced decorative textures depending on the desired appearance.
Unlike standard concrete where the aggregate remains hidden beneath a smooth cement surface, exposed aggregate incorporates natural stones as a visible design feature. The variation in stone size, shape, and colour allows for a customised appearance, with each installation carrying a unique character determined by the specific aggregate blend selected. This method has been used in Melbourne for decades, with local suppliers offering aggregate options sourced from Victorian quarries—primarily basalt from the Newer and Older Volcanics geological formations, along with granite and sedimentary rock materials.
The finish is achieved through a controlled washing process where the surface layer of concrete is exposed at a precise timing window. Surface retarders are applied to delay cement paste hardening on the top layer, allowing contractors to wash away the cement and reveal the underlying aggregate without dislodging the stones. This technique requires careful control—exposure too early risks aggregate loss, while waiting too long makes the cement paste difficult to remove. The result is a surface where approximately one-third of the smallest aggregate size becomes visible, creating the characteristic textured appearance.
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.
Long-Lasting Performance for High-Traffic Areas
The combination of structural concrete strength and durable natural stone aggregate creates surfaces capable of handling significant traffic loads over extended periods. For driveways, this means withstanding daily vehicle movements, visitor parking, and the concentrated loads that occur during turning and braking. For commercial applications, exposed aggregate handles pedestrian traffic volumes that would wear through less durable decorative treatments.
The key to this long-lasting performance lies in proper specification and installation. Strength grades appropriate to the intended use—N32 for standard residential applications, N40 for heavy-duty or commercial installations—provide the structural foundation. Adequate slab thickness, proper reinforcement with steel mesh or bars, and appropriate subbase preparation ensure the concrete can handle applied loads without cracking or settlement.
Control joints placed at correct spacing accommodate the natural shrinkage that occurs as concrete cures, preventing random cracking that would compromise both appearance and structural integrity. When these elements are correctly specified and installed, exposed aggregate delivers decades of reliable service with minimal degradation.
Is New Concrete Always Necessary?
Before committing to new exposed aggregate concrete, it’s worth having your existing surface professionally assessed. In many cases, concrete that appears worn, outdated, or damaged can be restored or resurfaced at a significantly lower cost than full replacement. A proper evaluation can help determine whether excavation is actually necessary, potentially saving thousands while still achieving a high-quality finish. Getting expert advice first ensures you’re making the right decision based on the condition of your current concrete, not just assumptions.

Frequently Asked Questions
How long does exposed aggregate concrete last?
When installed correctly and properly maintained, exposed aggregate concrete can last for many years. Its durability makes it suitable for high-traffic areas such as driveways and outdoor spaces.
What maintenance does exposed aggregate require?
Exposed aggregate maintenance focuses on cleaning and periodic resealing. Regular cleaning involves hosing off accumulated debris, occasional washing with mild detergent for stubborn dirt, and prompt attention to oil or chemical spills that might stain if left untreated.
Resealing is recommended every two to three years for residential installations, with more frequent attention for commercial areas or surfaces with high UV exposure. The sealer protects against water penetration, resists staining, and enhances aggregate colour appearance. Quality penetrating or surface sealers with UV stabilisers extend this protection between applications.
Avoid high-pressure washing at extreme settings, which can dislodge aggregate or damage sealer coatings. Standard pressure settings with appropriate nozzle distance are sufficient for effective cleaning without surface damage.
Is exposed aggregate suitable for Melbourne’s weather?
Exposed aggregate performs well in Melbourne’s climate conditions. The natural stone aggregates resist UV degradation that affects coloured or stamped concrete treatments. The textured surface provides reliable traction during wet weather—valuable given Melbourne’s rainfall distribution throughout the year.
Temperature variations in Melbourne rarely approach freeze-thaw conditions that damage concrete in colder climates, reducing one potential deterioration mechanism. Proper installation with attention to drainage prevents water ponding that might cause localised deterioration. The slip resistant properties suit Melbourne’s frequent rain events, maintaining safety for pedestrians and vehicle traction for driveways.
Coastal areas within our service region require attention to salt exposure, with appropriate sealer selection for marine environments.
Is resurfacing an option before installing new exposed aggregate?
Before committing to new exposed aggregate concrete, it’s worth checking whether resurfacing is a viable alternative. Many surfaces can be upgraded at a lower cost, making it important to assess the existing concrete before deciding on full replacement.
