Nupave recommended external concrete specification — Moorabbin
Group 1 — Bayside / Sand Belt — Brighton Group Sands
Concrete: N25 or N32 (depending on application)
Indicative regional ground conditions
Moorabbin 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
Nupave specifies N25 or N32 concrete depending on the intended application, anticipated loading, exposure conditions, selected finish and any site-specific engineering requirements. N32 may be specified where increased compressive strength, abrasion resistance or durability is required. 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.

Frequently Asked Questions
How long does a concrete driveway last in Moorabbin?
A properly installed concrete driveway in Moorabbin typically lasts 25 to 30 years or more. The sandy clay soil typical in this area needs proper compaction before pouring to ensure a long-lasting result. Regular cleaning is all it needs to stay in top condition.
How long does a concrete pour take?
Most residential concrete jobs in Moorabbin take one to three days depending on size and preparation needed. A standard driveway is typically poured in a single day, with curing time of around seven days before vehicle use.
Is sandy soil a concern for concrete foundations?
Sandy soil drains well, which is good for concrete. However, it can shift if not properly compacted. We ensure a solid compacted base before pouring to prevent settlement issues.
