Concrete Patio Costs in NSW

Concrete patios are one of the most popular outdoor renovation investments across NSW, providing a hard wearing all weather surface for outdoor entertaining, BBQ areas, alfresco dining, pool surrounds, and the integration zone between the back of the house and the rest of the garden. Pricing in 2026 spans from $80 per square metre at the entry level for plain broom finish work in a competitive metropolitan market through to $320 per square metre for polished concrete patios with feature aggregate exposure and premium sealer systems. A typical 30 to 40 square metre residential alfresco patio runs $2,400 to $5,600 fully installed for plain finish, while a 50 square metre feature patio with stamped or exposed aggregate finish runs $6,500 to $12,000.

The visual and functional impact of a quality concrete patio extends far beyond the slab itself, transforming the way a household uses its outdoor space and contributing meaningfully to property value at sale. Patio projects often coincide with related outdoor renovation work including pergola construction, outdoor kitchen installation, swimming pool surrounds, retaining walls, and landscape design, and managing the sequencing across these trades is part of the planning work. Reading multiple quotes side by side and understanding what each includes (and excludes) is essential because patio scopes vary substantially between contractors. The hub page on general concreting services in NSW covers the broader concreting category that includes patio work alongside slabs, driveways, pathways, and decorative finishes.

What a Concrete Patio Project Includes

A typical residential concrete patio project in NSW takes between three and seven days on site for a 30 to 60 square metre patio depending on access, finish type, and any integration work required for pergolas, outdoor kitchens, or other features. Day one usually covers site setup, demolition of any existing slab or pavers, excavation to subgrade, removal of spoil, and installation of any drainage or service penetrations beneath the patio. Day two involves spreading and compacting the road base, setting up formwork around the patio perimeter, placing pergola post footings if integrated, placing the steel reinforcement mesh on bar chairs, and pre pour checks. Day three is the pour itself, the screed, the float, the broom or trowel finishing, and the application of curing compound. Day four involves saw cutting expansion joints. Subsequent days cover any decorative finish work, sealer application, and final clean up.

The materials supplied to site for a typical 40 square metre patio include around 4 to 5 cubic metres of concrete delivered by truck mixer, around 12 to 14 square metres of mesh in standard sheets, 5 to 7 cubic metres of road base after compaction, formwork timber and stakes, expansion joint material, bar chairs, sealer or curing compound, and any decorative materials including stencils, colour hardener, or aggregate exposure retarder for decorative finishes. Pergola post footings are typically excavated as 400 by 400 by 600 millimetre concrete piers with the post brackets cast into the wet concrete. The project crew typically includes the lead concreter, one or two labourers, and where decorative finishes are specified often a specialist finisher who joins the team for the finishing day.

Beyond the slab itself, a properly scoped quote should include the disposal of excavation spoil, the saw cutting of expansion joints to control shrinkage cracking, the formation of falls to direct water away from the building, and the tying in of the new patio to existing surfaces such as house thresholds, doorways, pool surrounds, and adjoining paths. For patios that integrate pergola post footings, the quote should specify the footing dimensions, concrete grade, post bracket type, and number of posts. For patios designed to support outdoor kitchen islands or BBQ structures, the quote should specify any thicker slab sections required at those positions. Our concrete slab guide covers the structural slab work for projects where the patio extends beyond outdoor entertaining into a fully covered alfresco area subject to roof loads. Where existing patio surfaces need to be demolished and removed before the new pour, our concrete removal guide covers the demolition logistics.

Patio Finish Options

The finish on a concrete patio is the single most consequential decision for the visual outcome of the project. Plain broom finish is the workhorse residential specification, producing a fine ridged surface that provides slip resistance and ages predictably. Broom finish is the most affordable option at $80 to $140 per square metre and is well suited to functional outdoor areas where the practical considerations outweigh the visual ones. The downside is that broom finish can look utilitarian on premium properties and lacks the visual interest that decorative options provide.

Decorative finishes lift the visual impact of a patio considerably and are increasingly popular across NSW residential outdoor renovation projects. Exposed aggregate exposes the decorative stone within the slab to produce a textured natural finish that pairs well with garden settings; our exposed aggregate concrete guide covers the technique in detail. Stamped concrete uses textured rubber mats pressed into the freshly poured slab to mimic stone, brick, cobblestone, or timber plank patterns, providing the visual character of natural materials at concrete pricing; our stamped concrete guide covers patterns, colour systems, and the stamping process. Coloured concrete adds pigment through integral colour, dry shake hardener, or surface staining to create patios in earth tones, terracotta, charcoal, or designer colours; our coloured concrete guide covers the colouring methods.

Polished concrete is a premium patio finish that produces a smooth low maintenance surface with a refined aesthetic, particularly well suited to covered alfresco areas where the patio acts as an extension of indoor living space. Polishing involves grinding the concrete surface with progressively finer diamond abrasives to expose the cement matrix and small aggregate, then densifying with chemical treatment and sealing for protection. Our polished concrete guide covers the polishing levels, aggregate exposure options, and slip resistance considerations for outdoor polished installations. Trowelled and burnished finishes sit between plain broom and full polishing, producing a smoother surface than broom but without the labour intensity of full polishing, and are appropriate for sheltered alfresco areas where slip resistance is less critical because the surface is protected from rain.

Patio Sizing and Integration

Patio sizing should match the intended use rather than being driven solely by available space. A small alfresco area for casual outdoor dining serves four to six people and typically needs 12 to 18 square metres of slab with a 1.8 metre table and chairs, a small BBQ position, and circulation space. A medium entertaining patio for eight to ten people needs 20 to 35 square metres including a larger dining table, separate seating area, and BBQ kitchen area. A large family entertaining patio with multiple zones for cooking, dining, and lounge seating typically runs 40 to 80 square metres or more depending on the planned uses. Outdoor entertaining areas in NSW homes have grown substantially over the past decade, with the post pandemic shift toward indoor outdoor living driving a meaningful increase in patio sizes specified for new build and renovation projects.

Integration with the house and surrounding outdoor spaces affects both the design and the cost. Patios that step out from existing house thresholds need careful level matching to avoid creating a step at the doorway that defeats the indoor outdoor flow. Patios that abut existing paving, pool surrounds, or driveways need consideration of joint detailing and finish matching to produce a coherent outdoor space rather than a disconnected collection of slabs. Patios that incorporate pergola post footings should have the post positions designed before the slab is poured so that the footings can be integrated with the slab at the correct positions. Adding pergola posts after the slab is poured requires coring through the slab at each post position and is more expensive and visually compromised than integrating the footings during the original pour; our concrete coring guide covers the coring process used for retrofitted post footings.

Patios that connect to or surround swimming pools have additional design considerations covered in our concrete pool surrounds guide, including pool fence interaction, depth markers, slip resistance for wet conditions, and matching the patio finish with the pool coping. Patios that include outdoor kitchens or BBQ structures need consideration of utility connections (gas, water, electricity, drainage), the additional structural loads from heavy outdoor kitchen islands, and the protection of the slab from heat and grease. Driveways and pathways often connect to or are visible from the patio area, and matching finishes across these elements produces a more coherent outdoor design than treating each as a separate element. For driveway integration, our concrete driveway guide covers the driveway design considerations that often accompany patio work; for pathway connections, our concrete pathway guide covers the pedestrian connections.

Excavation and Sub-Base

Sub-base preparation for a patio is broadly similar to driveway and pathway work, with sub-base depth and quality determining whether the slab remains flat and uncracked over its service life. Clay subgrades across western Sydney, the Hawkesbury, and the Hills District are reactive and require a 75 to 100 millimetre compacted road base layer to provide a stable working platform and reduce the influence of soil moisture changes on the slab. Sandy subgrades along the Northern Beaches and parts of the Central Coast benefit from a similar road base layer to provide firm bedding for the slab. Sites with significant cut and fill across the patio footprint need careful attention to ensure the cut and fill zones consolidate consistently rather than settling at different rates over time.

The standard NSW residential patio sub-base specification is 75 to 100 millimetres of compacted DGB20 road base over an excavated and proofed subgrade, applied in accordance with Australian Standard AS 3727 for residential pavements. The road base is delivered in bulk, spread by hand or with a small bobcat, watered to optimal moisture content, and compacted with a vibrating plate compactor in lifts of no more than 100 millimetres at a time. Patios subject to outdoor kitchen loads, fire pit installations, or integrated spa pads may require thicker sub-base of 150 millimetres at those positions, with the slab also thickened to 125 or 150 millimetres locally to handle the concentrated loads.

Excavation depth for a patio typically runs 175 to 225 millimetres below finished slab level, accommodating 100 millimetres of slab and 75 to 125 millimetres of road base depending on slab specification. The relationship between the finished patio level and the existing house threshold, doorway, garden levels, and any adjoining slabs needs careful setting out at the survey stage before excavation begins. Most patios are designed to step down 30 to 50 millimetres below the house threshold to maintain weatherproofing of the building while keeping the step manageable for normal foot traffic. The NSW EPA publishes guidance on the classification and disposal of waste from residential excavation that applies to patio projects above approximately 5 cubic metres of spoil. For sites where existing patio slabs need to be demolished before the new pour, our concrete removal guide covers the demolition options.

Reinforcement and Concrete Grade

Steel reinforcement in a residential patio slab serves to control shrinkage cracking and provide some redundancy against differential settlement of the sub-base. The standard residential patio mesh specification is F62 or SL72 sheet mesh manufactured by BlueScope Steel and Liberty OneSteel to Australian Standards requirements, supplied in standard 6 by 2.4 metre sheets cut to size on site and laid on bar chairs to position the mesh in the upper third of the slab thickness. Heavier patios subject to outdoor kitchen loads or fire pit installations may require SL82 mesh with the slab thickened to 125 millimetres at the load positions.

Slab thickness for residential patios is typically 100 millimetres for general entertaining areas with normal furniture loads. Thickness should increase to 125 millimetres for patios that will support heavy outdoor kitchen islands, fire pits, or integrated spa pads where concentrated loads are anticipated. Thickness should also increase to 125 millimetres for patios on Class M or higher reactive sites under Australian Standard AS 2870, where the additional rigidity helps the slab bridge soil movement without cracking. Pergola post footings within the patio slab are typically 400 by 400 by 600 millimetres deep concrete piers with reinforcement bars, with the post bracket cast into the wet concrete during the pour or set with chemical anchors after the slab has cured.

Concrete grade for residential patios is typically 25 MPa supplied to Australian Standard AS 1379 by Boral, Holcim, Hymix, Adbri, Hanson, or another major supplier. Higher strengths of 32 MPa are appropriate for polished concrete patios where the harder surface produced by higher strength concrete improves the polished finish quality, for patios in coastal exposure zones within a kilometre of the surf where chloride attack is a durability consideration, and for patios subject to heavy outdoor kitchen or spa loads. Saw cut expansion joints at 3 to 4 metre intervals control where shrinkage cracks form. For decorative finishes including stamped or coloured concrete, the joint positions should be planned at design stage to coincide with pattern lines or feature elements rather than cutting joints arbitrarily after the pour. Our concrete cutting guide covers the saw work used to create joints, decorative score lines, and feature elements within the patio slab.

Drainage and Falls

Drainage falls and tie ins are critical for any outdoor concrete patio because the slab must shed rainwater quickly to prevent ponding and to keep water away from the adjoining building. A patio should fall away from the house at a minimum of 1 in 100 (one centimetre fall per metre run), with 1 in 80 being the more reliable specification for sites where wind driven rain can deposit substantial water on the slab during storm events. Cross fall of 1 in 50 to 1 in 100 across the patio width directs water to one side where it can be collected by an agricultural drain along the lower edge, a surface trench drain, or natural ground beyond the slab. The fall direction should also account for the position of furniture and the use of the patio, with the lowest area positioned away from main use zones to avoid water flowing through the entertaining area during rain.

Stormwater management on residential patios is regulated through council stormwater rules and the relevant Local Environmental Plan. Most metropolitan councils require that patio runoff be directed to either a dedicated stormwater pit on the property connecting to the council main, or to an absorption area such as a rain garden or soakwell on the property. Direct discharge across the property boundary onto neighbouring land is not permitted in most council areas because of the risk of nuisance flooding to adjoining properties. Where the patio falls towards the property boundary, an agricultural drain along the lower edge captures runoff and directs it to a legal discharge point. A competent concreter sets string lines and checks falls during formwork to confirm the falls are correct before the pour begins.

Covered alfresco patios under pergola roofs or solid roofing have different drainage considerations because most rainwater is intercepted by the roof and directed to gutters and downpipes rather than falling on the slab. The slab still requires falls because wind driven rain can enter the alfresco area in storm events, water from cleaning the slab needs to drain somewhere, and any water from beverages, food preparation, or pool wet feet needs to flow to a drainage point rather than ponding. Falls of 1 in 100 are typically adequate for covered alfresco areas. The interaction between the patio slab, the pergola post footings, and the roofing structure needs coordination at design stage, with the roof drainage typically discharging to a downpipe that connects to the broader site stormwater system. For projects where stormwater pit cores need to be cut into existing patios for new drainage connections, our concrete coring guide covers the diamond core drilling work.

NSW Licensing and Approvals

Concreting work valued above $5,000 in NSW must be performed by a contractor holding a current building licence under the Home Building Act 1989, administered by NSW Fair Trading. Most patio projects exceed this threshold given the typical 30 to 60 square metre patio sizes and current pricing levels. Engaging a contractor without verifying their licence number through the NSW Fair Trading licence check exposes the homeowner to significant risk if the work is defective or the contractor fails to complete it. The licence check is publicly available and takes only a few minutes; the time spent is the cheapest insurance available on a patio project.

Most residential concrete patios in NSW fall within exempt development under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008. The conditions for exempt development include compliance with maximum impervious area limits set by the relevant council Local Environmental Plan (typically 50 to 65 percent of the site for residential properties), no encroachment on easements, no interference with trees protected under a tree preservation order, compliance with side and rear setbacks (typically 900 millimetres to a side fence and 3 metres to a rear fence), and a maximum patio area generally limited to 25 to 30 square metres for fully exempt status. Larger patios may require complying development certification or a development application depending on the council and the broader site context. Heritage listed properties and properties within heritage conservation areas have additional requirements that often require a development application even for replacement of an existing patio.

Patios with integrated pergola structures, outdoor kitchens, or roofed alfresco areas have additional approval considerations because the structural elements above the slab are subject to building code requirements. Pergolas without roofing are typically exempt up to certain size limits. Pergolas with solid or impervious roofing become roofed structures subject to greater approval requirements, including potential development application requirements depending on size and position. Outdoor kitchens with gas appliances need plumbing and gas connections by licensed contractors, with the gas work subject to NSW Government energy regulations and certification requirements. The Service NSW portal provides access to council planning information for any NSW property to verify the specific exempt development conditions that apply. The Australian Competition and Consumer Commission publishes consumer guidance on residential building contracts that applies to patio work alongside other home improvement contracts.

Sealing and Slip Resistance

Sealing is the most important ongoing maintenance task for a residential patio and is what determines whether the slab still looks fresh in fifteen years' time or whether it has weathered to a dirty grey within the first five years. The first sealer application is typically included in the original installation contract for sealed finishes as a single coat applied two to four weeks after the pour once the slab has fully dried. Sealer choice depends on the patio's exposure conditions and the desired appearance: acrylic sealers are economical and provide a lightly enhanced wet look but require resealing every two to four years; polyurethane sealers cost more but last five to seven years with better stain resistance; silane and siloxane sealers penetrate the concrete rather than coating the surface and provide long lasting moisture protection without changing surface appearance. Our concrete sealing guide covers the full range of sealer chemistries, application rates, and reapplication intervals for residential patio work.

Slip resistance is critical for any outdoor patio because the slab is exposed to wet conditions from rain, pool wet feet, food and beverage spills, and cleaning. Australian Standard AS 4586 classifies surface slip resistance using the wet pendulum test method, with classifications from P0 (very low) to P5 (very high). Outdoor patios should target P3 or P4 ratings to provide reliable slip resistance under typical NSW rainfall, while pool surround patios and patios subject to wet feet should target P5. Plain broom finish concrete typically achieves P3 to P4 depending on broom texture. Exposed aggregate finishes typically rate P4 to P5 and are particularly well suited to wet area patios. Stamped concrete typically rates P3 to P4 depending on stamp pattern depth.

Polished concrete patios require particular attention to slip resistance because the polishing process reduces the surface texture and can drop the slip rating below acceptable levels for outdoor use. Modern polished outdoor patios use textured polishing systems or anti slip additives in the sealer to maintain P3 or higher ratings while achieving the visual benefits of polishing. The slip rating should be specified in the patio quote and confirmed with wet pendulum test results from the contractor's previous installations rather than left as an assumed property of the finish. For patios near pools where the slip rating requirement is most stringent, our concrete pool surrounds guide covers the additional slip resistance specifications and the pool fencing interaction that applies to pool surround patios.

Concrete Patio Costs Across Sydney

Sydney pricing for concrete patios reflects the breadth of the metropolitan outdoor renovation market and the wide range of site conditions encountered across different parts of the city. Inner Sydney work generally carries premiums for limited access, demolition of existing slabs, and heritage approval overhead. Outer Sydney work is generally cheaper because new build sites are simpler, access is straightforward, and there is more competition among contractors working within the major release area corridors. The pricing tables below capture typical cost ranges for a 40 square metre residential patio at three finish levels.

Inner Sydney patio pricing reflects the higher overhead of working within the constraints of inner urban properties. Many inner west and eastern suburbs sites have rear lane access only, requiring the concrete to be pumped or wheelbarrowed from the front street to the back yard patio position. Heritage conservation areas require council approval for works that would be exempt elsewhere, adding professional fee overhead and timeline cost to the project. Demolition of existing patio slabs, paving, or hardstands is more common on infill sites than on new build sites, adding a substantial line item to the project. The inner Sydney market also has strong demand for premium decorative finishes including polished concrete and feature stamped patios, with contractors specialising in these systems pricing accordingly.

Western Sydney and the Hills District represent the largest single market for patio construction in the state, driven by the major release areas across Marsden Park, Schofields, North Kellyville, Catherine Field, and Oran Park where new build dwellings frequently include rear patios as standard or upgraded inclusions. Pricing in these zones is consistently 15 to 25 percent below inner Sydney for the same patio specification due to easier site access, simpler logistics, and a competitive contractor market. New build patios pair particularly well with broader landscape projects and adjoining structures including pergolas, swimming pools, and outdoor kitchens; coordinating these elements at design stage produces a more coherent outdoor space than retrofitting them sequentially. For pool surround integration in particular, our concrete pool surrounds guide covers the design considerations.

Concrete Patio Costs in Regional NSW

Regional NSW pricing for concrete patios is generally 10 to 20 percent below Sydney pricing for comparable work, reflecting lower labour rates, simpler site access on most rural and regional residential properties, and lower compliance overhead. Regional jobs do however carry their own cost factors including travel time for concrete trucks from the nearest batching plant and smaller pour volumes that can attract minimum charge premiums from suppliers. Concrete supply across regional NSW is consistently sourced from Boral, Holcim, Adbri, and Hanson plants in the major regional centres.

Coastal regional NSW pricing across the Mid North Coast and Northern Rivers carries a small premium over inland regional pricing. Coastal sites within a kilometre of the surf require concrete grade upgrades from 25 to 32 MPa to resist chloride attack from airborne salt, adding to the concrete supply cost. Patio work is particularly popular across coastal areas where the indoor outdoor lifestyle is central to the property value, and beach houses and holiday homes frequently include feature decorative patios as part of broader renovation projects. The Northern Rivers around Byron Bay, Lennox Head, and Ballina has strong residential demand combined with limited contractor capacity, keeping patio pricing elevated relative to comparable inland work. For coloured patio finishes that complement coastal landscapes, our coloured concrete guide covers the colour options frequently specified for coastal patio work.

Inland regional NSW including the Central West, the New England, and the Riverina presents the most affordable patio pricing in the state. Sites are generally larger than metropolitan equivalents, access is straightforward, and concrete is supplied from local plants in Dubbo, Tamworth, Wagga Wagga, Albury, and Bathurst. The main cost factor for very rural properties is travel time for the concrete truck from the nearest batching plant, which can add $300 to $800 to a patio pour if the property is more than 45 minutes from the nearest plant. Combining a patio pour with another concrete element on the same property (a shed slab, a driveway, or a pathway) reduces the per square metre rate by sharing the truck delivery cost across the larger combined volume. Where patio resurfacing or overlay is more appropriate than full slab replacement, our concrete resurfacing guide covers the overlay options including microtopping, micro cement, and stamped overlay systems.

What to Look For in a Concrete Patio Quote

A quality concrete patio quote in NSW itemises the patio area in square metres, the slab thickness, the concrete grade, the mesh specification, the sub-base material and depth, the finish type, and the inclusions and exclusions for excavation, formwork, drainage, joint cutting, demolition, and disposal. Decorative finishes should specify the system being used (exposed aggregate stone type and exposure depth, stamped pattern, colouring method) and the brand of any colouring products or sealers being supplied. Pergola post footings should be specified with their dimensions, count, and post bracket type. Outdoor kitchen or BBQ slab thickening should be specified with dimensions and reinforcement schedule.

Reference checks for patio work focus on visible quality and the durability of decorative finishes over time. Drive past three to five completed patio projects from each prospective contractor and look at finish consistency across the slab, edge condition where the slab meets adjoining surfaces, joint condition, sealer wear, any staining or discolouration that has emerged, and the alignment of decorative pattern lines with the slab edges and joints. Phone references from previous customers are particularly valuable for decorative finishes because the visual outcome can vary substantially between contractors using nominally similar techniques. Ask references whether the contractor met the schedule, completed the work to specification, and rectified any defects raised during the project. The NSW Fair Trading licence check should be performed for any contractor handling work above the $5,000 threshold.

Payment terms must comply with the Home Building Act 1989, with a maximum deposit of 10 percent for contracts above $20,000 and 20 percent for contracts below that threshold. Patio projects with decorative finishes typically run a multi stage progress payment structure with a deposit at signing, a progress payment after pour, a progress payment after decorative finish completion, and a final payment after sealer application and final clean down. The contract should include the manufacturer warranty period for any sealer (typically two to five years), the contractor's six year statutory workmanship warranty under the Home Building Act for major defects, and a clear process for raising defects during the warranty period. Where patio work coincides with structural slab work for a covered alfresco area, our concrete slab guide covers the structural slab considerations that apply to roofed patio extensions.

Maintenance and Care

Routine maintenance for a residential patio is straightforward but should not be skipped because the consequences of neglect compound over time. Sweep regularly to prevent leaf litter, food debris, and organic matter from building up at edges and in joints where it can stain the surface and feed mould or moss growth. Pressure wash annually with a domestic pressure washer at moderate pressure, or every six months for patios heavily exposed to leaf drop, bird activity, or food preparation. Treat any spills (oil, wine, food, BBQ grease) promptly with a degreasing detergent and pressure wash before the stain has had time to penetrate the sealer. Avoid using strong acid based cleaners which can etch the sealer, and avoid metal bristled brushes which can scratch the surface.

Sealer reapplication is the most important periodic maintenance task. Acrylic sealers typically require reapplication every two to four years on a residential patio, with the timing visible in the gradual loss of the wet look effect that the sealer provides when fresh. Polyurethane sealers last five to seven years before requiring reapplication. Silane and siloxane penetrating sealers last seven to ten years and are typically reapplied when water no longer beads on the surface. The sealer reapplication process involves stripping any remaining sealer from the previous coat, cleaning the slab thoroughly, and applying the new sealer in accordance with the manufacturer's instructions for application rate and conditions. Sealer brands commonly used in NSW residential work include Ardex, Bostik, Davco, and Sika products, available through major hardware suppliers including Bunnings.

Surface defects that emerge over time can usually be remediated rather than requiring full slab replacement. Hairline shrinkage cracks are normal in any concrete slab and can be filled with a colour matched concrete crack sealer to prevent water ingress. Sealer wear is rectified by stripping the existing sealer and reapplying a fresh coat. Edge spalling and joint deterioration can be patched with concrete repair mortar matched to the original slab. For patios that have weathered to a point where the surface finish requires full renewal but the structure remains sound, our concrete resurfacing guide covers the overlay options including microtopping, stamped overlay, and resin systems that produce a fresh new surface without slab replacement. Where the slab has structural cracking caused by sub-base settlement or other underlying issues, our concrete repair guide covers the structural rectification options.
