Nupave recommended external concrete specification — Ringwood East
Group 2 — Eastern Ridge — Silurian Reactive Clay
Concrete: 32 MPa (all exposed aggregate)
Indicative regional ground conditions
Ringwood East is part of the Eastern Ridge belt, where the natural profile commonly contains Silurian shrink-swell clay. Regional conditions suggest reactive clay may be present on many sites, though individual property conditions vary. 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 around 40–60 mm of characteristic surface movement between wet and dry seasons on more reactive sites. 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 | 100 mm | 75–100 mm compacted crushed rock | SL72 (SL82 recommended) |
| Driveway (cars up to 3 t) | 100–125 mm | 100 mm compacted crushed rock | SL72–SL82 |
| Occasional truck (3–10 t) | 150 mm | 100–150 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 | 2.0 m – 2.4 m (tighter than the standard 2.7–3.0 m on stable ground) |
| 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.
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.
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.
Our Exposed Aggregate Services
Residential Exposed Aggregate
We create custom exposed aggregate installations for residential properties throughout Melbourne and surrounding areas. New driveways benefit from aggregate selection tailored to complement house colours and landscaping, with slab thickness and reinforcement designed for household vehicle loads and local soil conditions.
Pathways, patios, and outdoor entertaining areas receive the same attention to design and construction detail. Pool surrounds utilise aggregate types selected for barefoot comfort and slip resistance, with drainage slopes directing water away from the pool edge and house foundations.
Exposed aggregate resurfacing provides an option for existing concrete surfaces in sound structural condition. This overlay approach can transform plain or deteriorating concrete into attractive exposed aggregate finishes without the full excavation and base preparation required for new installations. Our consultation process assesses whether resurfacing is appropriate for each specific situation based on existing concrete condition and intended use.
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?
Many homeowners assume that worn or dated concrete needs to be completely replaced, but that isn’t always the case. Before committing to new exposed aggregate, a proper assessment can determine whether the existing slab is suitable for improvement rather than removal. This approach can reduce costs, minimise disruption, and still deliver a high-quality finish.
Choosing exposed aggregate for a new driveway or outdoor area is a strong option, but it’s always worth confirming whether replacement is actually required. In many situations, existing concrete can be enhanced or updated without the need for full excavation. Getting professional advice beforehand ensures you’re not overspending on work that may not be necessary.
If your concrete can be repaired or resurfaced, we’ll tell you — there’s no benefit to you replacing it unnecessarily.
