Nupave recommended external concrete specification — Frankston South
Group 2 — Eastern Ridge — Silurian Reactive Clay
Concrete: 32 MPa (all exposed aggregate)
Indicative regional ground conditions
Frankston South 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 is low maintenance when properly sealed, with resealing typically required every few years to protect against stains, moisture, and wear. General upkeep is simple, usually involving occasional cleaning with water or mild detergent to maintain its appearance. Compared to materials like pavers or timber, it requires significantly less ongoing maintenance while still delivering long-term durability.
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.
Long-Lasting Performance for High-Traffic Areas
Exposed aggregate is designed to handle high-traffic areas, combining structural concrete strength with durable natural stone to withstand daily vehicle use and foot traffic. When installed with the correct strength, reinforcement, and preparation, it delivers long-term performance without significant wear. This makes it a reliable choice for driveways and other areas where durability is essential.

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
Exposed aggregate is well suited to commercial applications, offering a durable, low-maintenance surface that performs under high pedestrian traffic while maintaining a professional appearance. It is commonly used for entrances, walkways, and outdoor areas, with finishes selected to align with the overall site design. When specified and installed correctly, it meets relevant standards and provides a long-lasting solution for both private and public spaces.
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.
Our approach is to recommend the best option, not the most expensive one

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.
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.
Can exposed aggregate be installed over existing concrete?
Exposed aggregate overlays can be applied over existing concrete surfaces that are structurally sound—no significant cracking, no active settlement, and adequate adhesion between old and new surfaces. This resurfacing approach provides a cost-effective alternative to complete removal and replacement where the existing base is serviceable.
Assessment of existing concrete condition is essential before recommending overlay installation. Surfaces with structural cracks, active movement, or delamination require repair or replacement rather than overlay. Where overlay is appropriate, specialised bonding techniques and overlay mixes ensure the new exposed aggregate surface adheres properly and performs as expected.
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.
What is exposed aggregate concrete?
Exposed aggregate concrete is a decorative finish where the top layer of cement is removed to reveal the natural stones within the mix. This creates a textured, durable surface commonly used for driveways, pathways, and outdoor areas.
