Exposed Aggregate Concrete Costs in Victoria

Exposed aggregate is the most popular decorative concrete finish across Victorian residential driveways, pathways, and pool surrounds, valued for its slip resistance, the texture it adds to a property, and the way it conceals minor staining and weathering far better than a smooth grey slab. Pricing in 2026 spans roughly $80 per square metre at the bottom of the band for commercial scale work using local crushed basalt through to about $210 per square metre at the upper end for banded designs with selected pebble and contrasting borders. Most suburban Melbourne driveways and pool surrounds fall between $110 and $170 per square metre once the typical site allowances for reactive clay sub-base preparation, decent quality aggregate, and a two coat sealer are factored in. The pricing assumes standard residential access, no significant demolition, and a flat to gently graded site, with steep blocks, removal of existing concrete, and limited access lifting these numbers materially.

The variable that catches most homeowners off guard is the difference in finished cost between a base specification job and one that uses a quality aggregate properly revealed and sealed. A driveway laid with bulk crushed basalt and a single coat of acrylic seal looks acceptable on day one but ages quickly, with surface oxidation, patchy aggregate exposure where the wash was uneven, and a sealer that hazes within twelve to eighteen months. The same driveway built with selected aggregate seeded into the surface, an even chemical retarder reveal, and a two coat hybrid sealer holds its appearance for five to seven years before the first reseal is due, and the difference between the two is typically only $20 to $35 per square metre. The hub page on general concreting services in Victoria covers the broader concreting category, and the related guide to concrete driveways in Victoria provides additional context on where exposed aggregate fits into the wider driveway category alongside plain, coloured, and stamped options.

What an Exposed Aggregate Project Includes

A complete exposed aggregate project in Victoria takes between three and six working days on site for a typical residential driveway depending on area, demolition involvement, and weather. Day one usually covers any demolition of existing concrete or asphalt, the cut and fill to bring the driveway to grade, and the placement and compaction of the crushed rock sub-base, which is most commonly 20 millimetre Class 3 crushed rock laid at 100 to 150 millimetres depth depending on subgrade conditions. Day two covers edge formwork, mesh reinforcement on bar chairs, and any final preparation before the pour. Day three is the pour itself, the screed and bull float, the seeding of additional aggregate where the mix uses surface seeding, the application of the surface retarder, and the cover up to allow the retarder to work overnight.

Day four involves the wash and reveal, where the surface is pressure washed at low to medium pressure to expose the aggregate to the design depth, and the full strip is rinsed clean of slurry and washed mortar. The job sequence allows the slab to gain enough strength overnight before the wash, so the bond between the cement paste and the aggregate is preserved while the surface paste is removed. Day five involves saw cutting of control joints at the spacing called for by the design, typically every 3 to 4 metres for a residential driveway and every 2 to 3 metres for narrower pathways, with the joints aligned to slab edges and any structural features. The first sealer coat is applied once the slab is dry, usually around day six or seven, with the second coat following 24 hours later.

The materials supplied to site for a typical 60 square metre driveway include around 7 to 8 cubic metres of concrete, 60 square metres of SL72 mesh in standard 6 by 2.4 metre sheets manufactured by BlueScope or Liberty OneSteel to Australian Standards specifications, 30 to 50 metres of edge formwork in form-ply or steel, around 200 to 400 kilograms of premium surface aggregate where the design uses surface seeding, surface retarder typically supplied in 20 litre drums with each drum covering around 200 square metres, sealer in 20 litre drums covering around 60 to 80 square metres per drum at the recommended two coat application rate, and bar chairs at the appropriate density for the slab thickness. The crew typically includes the lead concreter who manages the pour and finish, two to three labourers for prep and reinforcement, and the concrete truck driver delivering the supply. Larger pours where access prevents a direct chute delivery require a concrete pumper, and our concrete pumping guide covers the boom pump and line pump options used for residential driveways and pool surrounds in Melbourne.

Beyond the slab itself, a properly scoped quote should include the disposal of demolition spoil and excavated subgrade, any temporary site works such as silt fencing where required by council, the saw cutting of control joints, drainage falls to kerb or to the property boundary, and the protection of the new surface during cure. Removal of an existing driveway before pouring the new exposed aggregate slab adds $25 to $45 per square metre depending on slab thickness and reinforcement, with disposal subject to EPA Victoria waste classification rules where the disposal site applies. Our concrete removal guide covers the demolition logistics in detail, and our concrete cutting guide covers the saw work involved in expansion joints, slab separation, and tying new work to existing surfaces.

Aggregate Types and Selections

The aggregate selection is the single most important decorative decision in an exposed aggregate project and is the variable that most directly affects the finished appearance. Local crushed basalt, often called bluestone in Melbourne, is the dominant aggregate across Victoria, supplied from Western District quarries and from operations around Bacchus Marsh, Tylden, and the basalt belt running through western Melbourne. The 10 millimetre crushed basalt produces a dark grey to charcoal finish with a moderately angular texture, complements the bluestone vernacular across inner Melbourne, and is the most economical aggregate choice. Smaller 7 millimetre crushed basalt produces a finer texture suited to pool surrounds and pathways where bare feet will be common.

River pebble aggregates round out the next tier of common selections, with golden, mixed colour, and white river pebbles available from Goulburn, King, and Murray river sources processed through Victorian aggregate suppliers. Rounded river pebbles produce a softer underfoot feel than crushed basalt and are popular for pool decks, alfresco patios, and any application where bare feet are expected to make contact with the surface regularly. The colour mix can be adjusted by blending different pebble sources at the supply yard, with golden mixed blends sitting in the most popular price band and pure white quartz pebbles attracting a premium because of the quarry source and the additional washing required to keep them clean during transport. Selected pebble blends matched to the building or landscape design are available at additional cost.

Quartz aggregates, including white quartz, smoky quartz, and rose quartz blends, sit in the premium aggregate band and produce light, reflective finishes that brighten shaded areas and contrast strongly with darker landscaping. Granite aggregates from north east Victoria, around Beechworth and Stanley, produce speckled finishes with mixed grey, pink, and black grain visible after washing. Recycled glass aggregates have grown rapidly in Victoria over the last several years driven by the construction sector's push toward circular economy materials, and the recycled glass finish produces a distinctive sparkling appearance with green, amber, and clear glass fragments visible in the surface. Castlemaine slate fragments and other local slate aggregates are popular for heritage area projects across Castlemaine, Daylesford, and the goldfields, providing a finish that complements the existing slate roofing and stone walling common to the area.

Aggregate sizing affects both the appearance and the slip resistance of the finished surface. Smaller aggregates around 5 to 7 millimetres produce a finer texture suited to pool surrounds, alfresco zones, and pathways where comfort underfoot matters. Standard 10 millimetre aggregate is the most common size for driveways and general residential work, balancing texture with practical durability under vehicle traffic. Larger 14 to 20 millimetre aggregates are used on commercial pavements where heavy vehicle traffic, forklift wear, or fire truck access is anticipated, and produce a more aggressive texture that is durable but uncomfortable for bare feet. The aggregate size and proportion are agreed at quote stage and should be confirmed on the delivery docket alongside the concrete grade. For projects combining aggregate with coloured base concrete, our coloured concrete guide covers integral and topical colour options.

Site Preparation and Sub-Base

Site preparation is where the difference between a long lasting exposed aggregate slab and one that cracks or settles within five years is decided. Most of metropolitan Melbourne sits on Newer Volcanic basalt clays across the Western Basalt Plains, Older Volcanic clays through inner suburbs, and Silurian mudstone through the eastern suburbs and the Yarra Valley, with parts of bayside on the more stable Brighton Group sands. The reactive clays in the western and northern growth corridors expand and contract significantly with seasonal moisture variation, and a driveway laid directly onto undisturbed clay subgrade without an adequate crushed rock sub-base will fracture along predictable lines as the clay moves beneath it.

The Victorian standard for residential driveway sub-base is 100 to 150 millimetres of compacted Class 3 crushed rock laid over the trimmed subgrade, with the crushed rock supplied from local quarries across the Yarra Valley, Lang Lang, and the Western District. Class 3 crushed rock is the workhorse pavement material specified for driveway and pavement sub-base across Victoria and is suitable for both residential vehicle loading and light commercial work. Class 2 crushed rock is used where heavier traffic loadings apply such as commercial driveways or carpark entries. Compaction is critical and should be done in two layers for a 150 millimetre sub-base, with each layer compacted to 95 percent maximum dry density using a vibrating plate compactor or a small roller depending on the site size.

Sites that have been recently filled, sites with poor drainage, and sites within the highly reactive western and northern growth corridors often require additional sub-base depth and geotextile separation between the subgrade and the crushed rock. Geotextile fabric prevents fines from migrating up into the crushed rock layer and softening it over time, particularly relevant on sites where the subgrade contains silt or where stormwater pools beneath the driveway during heavy rain. The cost of a properly prepared sub-base on a reactive site is typically $15 to $25 per square metre on top of the standard preparation, and is among the most cost effective additions a homeowner can make. Skipping the sub-base preparation to save the cost almost always results in differential settlement, surface cracking, and the need for resurfacing or replacement within five to ten years rather than the twenty plus year service life that a properly prepared driveway should deliver. For sites where existing driveway issues need rectification before new work can proceed, our concrete repair guide covers the rectification options including underpinning and overlay.

Mix Design and Concrete Grade

Concrete for exposed aggregate work in Victoria is typically supplied to Australian Standard AS 1379 by Boral, Holcim, Hanson, Adbri, or one of the regional batchers operating across Geelong, Ballarat, Bendigo, and the major regional centres. The standard residential exposed aggregate mix is 25 MPa concrete with a slump in the 80 to 100 millimetre range, providing enough workability for surface seeding and finishing while still allowing a clean reveal once the retarder is washed off. Higher 32 MPa grades are appropriate for driveways subject to heavier vehicle loading, commercial entries, and projects within a few hundred metres of the bay where chloride attack from airborne salt is a long term durability concern.

The mix design for exposed aggregate work has two main approaches. Through mix designs incorporate the decorative aggregate throughout the full depth of the slab and rely on the retarder and wash to reveal the surface aggregate, which is the simplest method and works well where the local crushed basalt or river pebble is available in adequate volumes from the supplier. Surface seeded designs use a standard 20 millimetre aggregate concrete for the bulk of the slab and seed the decorative aggregate into the surface during finishing, which gives access to premium aggregates that would be uneconomic to use through the full slab depth. Surface seeding is the standard method for white quartz, recycled glass, and selected pebble blends because the decorative aggregate is concentrated where it will be visible.

Colour can be added to the base concrete to produce a tinted background that contrasts with or complements the exposed aggregate, and is supplied as integral oxide colour batched into the mix at the supplier's plant. The most common base colours across Victorian residential exposed aggregate work are charcoal, terracotta, sandstone, and mid grey, with the integral oxide adding $15 to $30 per square metre to the supply cost depending on colour intensity. Through colour produces a more durable result than topical colour applied to the surface because there is no risk of the colour wearing through to expose grey concrete underneath. The mix supplier's batching plant is the appropriate place to adjust the colour, and reputable suppliers will provide a sample slab on request for any non standard colour. Our coloured concrete guide provides a fuller treatment of the integral colour options and the durability characteristics of different oxide systems.

Reinforcement for an exposed aggregate driveway is typically SL72 mesh laid on bar chairs at the design height within the slab thickness, with the mesh providing crack control across the slab area. Heavier SL82 mesh is appropriate for thicker slabs at 125 to 150 millimetre depth, commercial work, or driveways on reactive sites where additional reinforcement is justified. Trench mesh is generally not required for a residential driveway, but is added at slab edges and around any deep recesses or service penetrations where structural continuity matters. The reinforcement specification should be confirmed in the quote and verified on site before the pour, with photographs of the reinforcement in position being a useful record for warranty purposes. Concrete grade should be confirmed from the delivery docket on each truck before the pour proceeds, and any variation from the specified grade should be raised with the supplier before placement begins.

Wash and Reveal Techniques

Exposing the aggregate is the defining step of the process and is the moment where finish quality is determined. Three main reveal techniques are used in Victoria. The traditional water wash technique is the oldest method and involves washing the slab surface with water and a stiff brush within a few hours of the initial set, before the cement paste has hardened enough to bond firmly to the aggregate. Water wash works well for small residential pours where the concreter can monitor the slab closely throughout the cure, but becomes difficult to control evenly across larger pours because the rate of cure varies between the leading and trailing edges of the slab.

The chemical retarder technique is the standard method for medium to large residential and commercial work and uses a sprayed surface retarder applied immediately after the initial trowel finish. The retarder slows the surface cement hydration without affecting the underlying slab, holding the surface paste in a workable state overnight while the slab below gains its initial strength. The next day, the surface paste is washed off with low to medium pressure water, exposing the aggregate to a depth set by the strength of the retarder used. Different retarder strengths are available to give shallow, medium, or deep aggregate exposure, and the choice depends on the aggregate size and the design intent. Chemical retarder reveals are the most consistent technique across larger pours and are the dominant method on Victorian commercial work.

Mechanical retardation through covering the slab with retarder coated paper and removing it the next day is occasionally used for very specific finishes where neither water wash nor liquid retarder gives the required result. The technique is more labour intensive and is generally only used by specialist decorative concrete contractors on premium residential projects where appearance is the dominant consideration. The reveal depth determines whether the finished surface shows just the top of the aggregate, half the aggregate diameter, or close to the full aggregate exposed, and each depth produces a different appearance and a different slip resistance characteristic. Shallow reveals produce a smoother surface suited to pool surrounds and patios where bare feet will be common, while deeper reveals produce a more textured surface suited to driveways and external pathways. The reveal depth should be agreed at quote stage and confirmed against a sample slab where possible before the main pour proceeds.

Sealing and Protection Systems

Sealing is essential on exposed aggregate concrete and is the single most important factor in long term appearance and stain resistance. Unsealed exposed aggregate weathers to a dull grey within a year and accumulates oil, leaf tannin, and tyre marks that become difficult to remove. The sealer functions as a sacrificial barrier between the surface and contaminants, prevents water ingress into the aggregate matrix, and brings out the colour of the aggregate and any base concrete colour. Three main sealer technologies are used across Victorian exposed aggregate work, each with different durability, appearance, and cost characteristics.

Acrylic sealers are the most common and most affordable option, supplied in solvent based or water based formulations and applied at two coats with light brooming or rolling. Acrylic sealers add a wet look gloss that significantly enhances aggregate colour and produces the dark wet appearance that many homeowners associate with finished exposed aggregate. The downside is durability, with acrylic sealers typically requiring resealing every two to three years on a vehicle traffic driveway and every three to five years on pedestrian pathways. UV degradation, hot tyre pickup where vehicles park in the same spot for extended periods, and seasonal moisture cycling are the main wear mechanisms.

Penetrating siloxane and silane sealers sit in the middle of the price band and work by penetrating the concrete and lining the capillary structure with a hydrophobic film, leaving the surface looking essentially natural rather than glossy. The penetrating action protects the concrete from within rather than relying on a surface film, and the result is much longer service life with typical resealing intervals of five to seven years on driveways and seven to ten years on lower wear applications. The trade off is that penetrating sealers do not produce the wet look gloss that acrylic sealers give, and the colour enhancement is more subtle. For applications where stain resistance and longevity matter more than the dark wet look, penetrating sealers (sometimes applied by specialist coating applicators who carry spray equipment) are the better choice.

Hybrid polyurethane sealers and high performance polyaspartic sealers sit at the premium end of the market and combine the appearance of acrylic with much of the durability of penetrating sealers. These products are typically used on premium residential work, commercial entries, and any application where appearance and durability both matter. Cost per square metre at application is roughly double that of acrylic, but the resealing interval extends to five to eight years on driveways and the surface holds gloss far better through the wear cycle. Surface preparation for sealer application is critical and is often the failure point on cheaper sealing jobs, with the slab needing to be fully clean, dry, and free of any laitance or residual retarder before the sealer can bond properly. Our concrete sealing guide covers the technical detail on each sealer technology and the application protocols, and the concrete resurfacing guide covers the surface renewal options for older slabs where sealing alone is no longer sufficient.

Pour Sequencing and Curing

Pour sequencing for an exposed aggregate driveway is typically planned as a single continuous pour completed in a single day, avoiding cold joints across the visible decorative surface. A standard 60 to 80 square metre driveway requires 7 to 10 cubic metres of concrete, delivered by one or two truck loads sequenced 15 to 30 minutes apart to keep the surface workable across the pour. The pour starts at the upper end of the driveway and progresses toward the kerb, with the screed worked across the slab from one edge to the other to maintain consistent levels and falls. Larger pours over 200 square metres may need three or four trucks, with the pump or chute repositioned as the pour advances down the slab.

Weather management during the pour is critical for exposed aggregate finishes because the timing of the retarder application and the initial trowel finish depends on the rate at which the concrete sets. Hot summer pours across northern and western Melbourne can move very quickly, with the surface needing to be retarded and covered within an hour of placement, and additives including water reducing admixtures and retarders are commonly used to extend the working window. Winter pours in cooler conditions across the Dandenongs, the Yarra Valley, and regional Victoria can run the opposite direction, with the slow cure rate delaying the wash and reveal sometimes by 36 to 48 hours rather than the standard overnight window. The supplier and the concreter agree the mix admixture package based on the day's conditions, and the pour timing should not be set without weather check first.

Curing protocol after the wash and reveal phase is similar to standard concrete curing requirements. The slab must remain damp for the first 7 days while the cement hydration progresses to design strength, with the dampness usually maintained by light water spraying once or twice a day or by covering with hessian during very hot weather. Foot traffic should be kept off the slab for 48 hours after the pour, light vehicles should be kept off for 7 days, and heavy vehicles including delivery trucks and trade vehicles should be kept off until day 28 when the slab approaches design strength. Premature loading is a common cause of surface cracking and aggregate displacement that is entirely preventable with simple barrier tape and a homeowner who follows the curing schedule. For projects requiring saw cutting after the pour, our concrete cutting guide covers the diamond saw work involved in joint formation and any tying in to existing slabs. Where the existing surface needs to be ground or profiled before new work proceeds, our concrete grinding guide covers the surface preparation options.

Victorian Registration and Building Code

Domestic building work in Victoria valued above $10,000 must be performed by a contractor registered as a Domestic Builder with the Building and Plumbing Commission under the Building Act 1993, with concrete work that forms part of domestic building work falling within this requirement. Standalone concrete work such as a driveway, pathway, or patio that is not part of a broader building project sits in a different category, with the work governed by general consumer contract law and the Domestic Building Contracts Act 1995 protections rather than the building registration requirement. The practical reality is that most homeowners benefit from engaging a registered Domestic Builder or a contractor working under the supervision of one, because the registration carries the insurance, the warranty, and the dispute resolution framework that protect the homeowner if something goes wrong.

Domestic Building Insurance, formerly called builders' warranty insurance, is required in Victoria for any domestic building contract above $16,000 and provides the homeowner protection against the contractor's death, disappearance, or insolvency during the warranty period. The insurance is taken out by the builder and provided to the homeowner as a certificate before any deposit is paid, and is administered through the BPC. Concrete contracts above $16,000 that fall within the domestic building work definition need this insurance in place, which captures most full driveway and large patio projects across Melbourne. The Consumer Affairs Victoria guidance on domestic building contracts is the appropriate reference for homeowners who want to verify their rights before signing.

Building permit requirements for exposed aggregate work depend on the project. Driveways within property boundaries on existing dwelling sites generally do not require a building permit, but a planning permit may apply where the property sits within a heritage overlay, a design and development overlay, or a vegetation protection overlay. Heritage listed properties and properties within heritage conservation areas across inner Melbourne, and across regional centres including Castlemaine, Daylesford, Beechworth, and Queenscliff, have additional approval requirements that can extend the project timeline by two to twelve weeks. The Victorian Government planning portal provides access to planning scheme information for any Victorian property, and the local council's planning department is the appropriate first contact for any property with overlays. The Australian Competition and Consumer Commission publishes consumer guidance on residential building contracts that applies to concrete work alongside other home improvements. Site safety on Victorian residential and commercial concrete work is governed by the WorkSafe Victoria framework, which sets out the obligations that apply to contractors and to homeowners as principal contractors where they engage trades directly.

Exposed Aggregate Costs Across Melbourne

Melbourne pricing for exposed aggregate work reflects three main factors: the prevailing soil conditions across different parts of the metropolitan area, the density of competing decorative concrete specialists in the local area, and the typical complexity of access on residential blocks. Inner Melbourne work generally carries premiums for limited access, demolition of existing concrete or asphalt on infill sites, heritage approval overhead, and the need for pumping where truck access is restricted. Outer Melbourne work in the growth corridors is generally more affordable because new build sites have straightforward access, simpler site geometry, and a competitive pool of decorative concrete contractors working at scale. The pricing tables below capture typical cost ranges for a standard 60 square metre driveway and a 30 square metre pool surround across the main metropolitan zones.

Inner Melbourne pricing for exposed aggregate carries premiums driven by access difficulty, the higher proportion of demolition required on infill driveways, and the complexity of working within tight urban footprints. Many properties across Carlton, Fitzroy, Collingwood, and East Melbourne have rear lane access only, requiring concrete pumping rather than direct truck delivery and adding $400 to $1,200 to the project cost depending on pump type and distance. Heritage overlays across inner Melbourne, North Melbourne, and Albert Park have additional approval requirements that affect the timeline and may constrain the choice of aggregate where the council seeks to maintain a particular streetscape character. Demolition (typically performed by paving and demolition contractors) of existing tessellated tile, bluestone paving, or older concrete carries disposal cost considerations, with bluestone often kept and reused on the property rather than disposed of.

The west and north growth corridors represent the largest volume of new exposed aggregate driveway work in the state, driven by the major residential growth areas across Wyndham, Melton, Hume, and Whittlesea. New build sites in Tarneit, Truganina, Wyndham Vale, Point Cook, Manor Lakes, Aintree, Fraser Rise, Craigieburn, Donnybrook, and Mickleham typically have straightforward access for trucks and pumps, simple site geometry, and a competitive pool of contractors working at scale across multiple developments. Pricing per square metre is consistently 15 to 25 percent below inner Melbourne for the same finish, and project turnaround from quote acceptance to completed driveway can be as short as two to three weeks during normal demand periods. The reactive Newer Volcanic clay subgrade across these corridors requires the deeper crushed rock sub-base discussed in the site preparation section, and that allowance should be visible in any quote on a growth corridor block. For pathway work that often accompanies new house exposed aggregate driveways, our concrete pathway guide covers the residential pedestrian concreting that complements the main driveway work.

Bayside Melbourne pricing reflects two specific factors. The first is the prestige market across Brighton, Hampton, Sandringham, Black Rock, Beaumaris, and Mentone where premium aggregate selections, banded designs, and high specification sealers are standard, lifting the average per square metre rate. The second is the salt exposure within a few hundred metres of the bay, where airborne chlorides accelerate concrete deterioration and 32 MPa concrete grade with marine specification reinforcement is a sensible upgrade over the standard 25 MPa specification. Pool surrounds across bayside are a dominant exposed aggregate application, with the slip resistance of the textured surface being the primary driver alongside aesthetics. For patio and entertaining area work that often accompanies pool surround exposed aggregate, our concrete patio guide covers the broader entertaining area decisions.

Exposed Aggregate Costs in Regional Victoria

Regional Victorian pricing for exposed aggregate work is generally 10 to 20 percent below Melbourne pricing for comparable specifications. Regional sites benefit from simpler access on most rural and regional residential blocks, lower labour rates, and lower compliance overhead in many councils. Concrete supply is sourced from Boral, Holcim, Adbri, Hanson, and a range of regional independent batchers across Geelong, Ballarat, Bendigo, Shepparton, Mildura, Wodonga, Warrnambool, and the Latrobe Valley. The aggregate availability differs from Melbourne in some regional areas, with some quarries supplying distinctive local aggregates that are less common in metropolitan work, including granite from the Beechworth area, slate from the Castlemaine and Daylesford goldfields, and river pebbles from major regional rivers.

Geelong and the Bellarine Peninsula represent the largest regional market in Victoria for exposed aggregate work, driven by a strong residential construction sector across Armstrong Creek, Lara, Curlewis, and Drysdale, and the holiday home market through Ocean Grove, Barwon Heads, Queenscliff, and Point Lonsdale. Pricing tracks slightly below Melbourne western suburbs and contractor availability is generally good across the region, with both Geelong based decorative concrete specialists and contractors travelling from Melbourne for larger projects. Salt exposure on coastal Bellarine sites warrants the same 32 MPa grade upgrade discussed for Melbourne bayside, with the additional consideration that some properties through the Surf Coast around Torquay, Anglesea, Aireys Inlet, and Lorne face significant wind driven salt exposure that justifies a high specification penetrating sealer rather than acrylic.

Ballarat and Bendigo pricing reflects the substantial residential construction activity in both centres, with new home developments around Lucas, Alfredton, Brown Hill, and Mount Clear in Ballarat, and around Strathfieldsaye, Junortoun, Maiden Gully, and Kangaroo Flat in Bendigo. Both centres have established decorative concrete specialists and good aggregate supply, with local quartz, granite, and basalt aggregates available alongside the standard Victorian sources. Frost is a real consideration in both centres during winter, with overnight temperatures regularly reaching minus 2 to minus 5 degrees in Ballarat and the Central Highlands, and the pour timing should avoid frost risk through mid June to mid August unless the slab can be effectively protected during the first 24 hours after pour. Concrete that freezes within the first 24 hours of pour suffers permanent strength loss and surface damage, and is one of the few defects that cannot be retrospectively rectified short of slab replacement.

Mornington Peninsula pricing sits between Melbourne south-east growth corridor pricing and inner Melbourne pricing, reflecting the holiday home and prestige residential market across Mount Eliza, Mount Martha, Sorrento, Portsea, Flinders, and Red Hill. Demand peaks through the spring months from September to December as homeowners commission work in advance of the summer use season, and lead times can extend to eight to twelve weeks during peak periods. Salt exposure across the bay side and the back beach of the peninsula is significant, with the back beach exposure from Cape Schanck around to Flinders being the most aggressive marine environment in Victoria for concrete durability. Penetrating sealers and 32 MPa concrete grade are sensible upgrades on any peninsula work within a kilometre of the coast. For pool surround projects across the peninsula, our concrete pool surrounds guide covers the additional considerations relevant to pool deck work in coastal environments.

The Latrobe Valley, Goulburn Valley, and inland regional Victoria including the New England side of the north east offer the most affordable exposed aggregate pricing in the state. Local concreters in Traralgon, Morwell, Sale, Shepparton, Wodonga, and Mildura deliver high quality work below metropolitan rates because the cost base is lower and most sites are simple to work. Travel time for concrete trucks from the nearest plant is the main cost factor for very rural properties, which can add $200 to $800 to a pour where the property is more than 45 minutes from the batching plant. Mobile batching is available for very remote sites and typically becomes economic for pours above 30 cubic metres. For projects requiring resurfacing of an older driveway rather than complete replacement, our concrete resurfacing guide covers the overlay options that can produce a fresh exposed aggregate finish over a sound existing slab.

What to Look For in an Exposed Aggregate Quote

A quality exposed aggregate quote in Victoria is a detailed multi page document that itemises the area to be poured, the slab thickness and reinforcement specification, the concrete grade, the aggregate type and size, the reveal technique, the sealer specification including number of coats and product, the inclusions and exclusions for excavation, demolition, sub-base, formwork, drainage, joint cutting, and disposal. The quote should reference a specific aggregate sample where possible, ideally with a photograph or with the option to inspect a recent completed project using the same aggregate before signing. A quote without aggregate sample reference is incomplete because the appearance varies significantly between aggregate sources even when the type description is identical.

Reference checks are critical for decorative concrete because aggregate appearance and reveal quality are subjective and the only reliable way to assess a contractor's work is to see completed projects in person. Ask each prospective contractor for the addresses of three to five completed exposed aggregate driveways from the past two years that you can drive past, ideally using the same aggregate selection or similar finish as your project. Check the evenness of the reveal across the slab, the alignment and squareness of the slab edges, the joint cuts and crack control, the quality of the sealer (look for hazing, fading, or hot tyre pickup), and any signs of edge cracking or settlement that might indicate sub-base issues. Phone references from previous customers are particularly valuable for decorative concrete and should focus on whether the finished appearance matched expectations, whether the contractor met the schedule, and whether any defects were rectified without dispute.

Watch for quotes that come in materially below the others in the field, because the most common ways of cutting price on exposed aggregate work are reducing the sub-base thickness, substituting cheaper aggregate, applying only a single coat of sealer rather than two, and using a thinner slab than specified. Each of these substitutions reduces the project's service life by years rather than months and is invisible at handover. Ask for the concrete delivery dockets after the pour to confirm the grade and volume delivered, ask for the sealer product label or data sheet to confirm the specification used, and consider an independent visual inspection at the reveal stage if the project value justifies the small additional cost. The Consumer Affairs Victoria guidance on getting quotes from tradespeople is the appropriate framework for any homeowner approaching this work.

Payment terms for exposed aggregate work in Victoria should comply with the Domestic Building Contracts Act 1995 where the work falls within the domestic building work definition. The Act sets a maximum deposit of 10 percent for contracts above $20,000 and 20 percent for contracts of lower value, with progress payments tied to defined work stages such as preparation complete, slab poured, and sealing complete. Independent stand alone driveway work that does not meet the domestic building work definition is governed by general consumer contract law, but the same principles around staged payment, written contracts, and clear scope of work apply as best practice regardless of the legal classification. Disputes that cannot be resolved between the parties can be escalated to the Victorian Civil and Administrative Tribunal, which hears domestic building disputes alongside other consumer matters. For sites where existing concrete needs to be removed or coring work is needed for service penetrations, our concrete coring guide and concrete cutting guide cover the specialist diamond saw and core drilling services.

Maintenance and Resealing

Exposed aggregate concrete is generally low maintenance once installed correctly, but the sealer system is consumable and will require periodic renewal across the life of the slab. The first reseal is typically due two to three years after the original install for an acrylic sealer on a vehicle traffic driveway, three to five years for a residential pathway with the same sealer, and five to seven years for a penetrating siloxane or polyurethane system. Visible signs that resealing is due include the loss of colour intensity on the aggregate, water no longer beading on the surface, increased visible staining from oil or leaf tannin, and a dull rather than satin or gloss finish on previously sealed surfaces.

Reseal preparation is the single largest determinant of how well the new sealer performs and is often the corner cut on cheaper resealing jobs. The slab must be thoroughly cleaned with high pressure water at the appropriate pressure for the surface, with any remaining sealer removed using a chemical stripper where the existing system is incompatible with the new product. The slab must then be fully dry before sealer application, typically requiring 24 to 48 hours of dry weather between cleaning and sealing. Applying sealer to a wet or partially clean surface is the most common reseal failure and produces hazing, peeling, and patchy appearance that requires complete sealer removal and reapplication to rectify.

Spot maintenance between resealing addresses common surface issues without requiring full reseal. Oil drips on driveways respond to dish detergent and warm water within the first day, and to commercial concrete cleaner formulations beyond that window. Leaf tannin staining from autumn fall responds to oxygen bleach treatment but should not be treated with chlorine bleach, which will damage the sealer. Hot tyre pickup on dark coloured slabs is best prevented by parking different vehicles in different positions during summer when bitumen tyre compounds are softest and most liable to leave marks. Any maintenance or cleaning approach should be tested on an inconspicuous area first to confirm the sealer responds well to the cleaning agent. Our concrete sealing guide covers the resealing process in detail and the products suited to different exposure conditions across Victoria.

Cracking in exposed aggregate concrete generally falls into three categories. Hairline cracks across the slab surface are normal and reflect the concrete's natural shrinkage during cure; saw cut control joints are placed specifically to concentrate this cracking along predictable lines where it is invisible in the finished surface. Cracks running between control joints typically indicate either inadequate joint spacing for the slab dimensions or differential movement at the sub-base level, and may need monitoring over a season to determine whether they are stable or progressive. Wide cracks above 2 millimetres width, cracks with step displacement across the crack line, or cracks that progress diagonally across the slab indicate structural movement and warrant assessment by a qualified structural engineer or experienced concrete repair specialist. Our concrete repair guide covers the full range of structural slab repair options including epoxy injection, slabjacking, and partial replacement, while our concrete grinding guide covers the surface levelling options where the slab is sound but the surface is no longer flat enough for its intended use.
