How Much Does a Concrete Patio Cost in Perth? 2026 Guide

A concrete patio in Perth typically costs between $65 and $150 per square metre , depending on the finish you choose, the size of the area and how much site preparation is involved. At Woodlands Construct, we have been installing concrete patios across Perth for over a decade, and one of the most common questions we get is: how much will this actually cost me? This guide gives you honest, up-to-date numbers for 2026, the factors that move the price up or down, and exactly what you should expect from a quality concreting job.

The table below covers the most common patio projects we quote on across Perth. These figures reflect current material and labour costs and assume a standard residential site with reasonable access.

These are estimates, not quotes. Your actual price depends on the factors we cover below. If you want a fixed number for your specific job, get a free quote from our team.

Finish Type

The finish is the single biggest price variable. Plain broom-finished grey concrete sits at the lower end of the range and suits functional areas like side passages or back utility spaces. Exposed aggregate costs more because the top layer of cream must be washed away to reveal the stone underneath, and the aggregate itself, often sourced through suppliers like Boral, carries a materials premium. Honed concrete costs the most of the standard finishes because it requires diamond grinding and polishing after the slab cures. If you want to understand the full range of finishes available, our guide on concrete patio installations across Perth breaks each one down in detail.

Size and Shape

Larger slabs cost more in total but often come down in price per square metre because setup costs, formwork time and truck delivery fees spread across a bigger job. A simple rectangular 25 sqm patio in Clarkson or Butler will almost always cost less per square metre than a custom-shaped 15 sqm patio with curved edges and multiple control joints. Complex shapes require more formwork time and closer attention during the pour.

Site Conditions and Excavation

Perth soil varies significantly across the metro area. Sandy coastal soil in suburbs like Scarborough or Trigg is generally easy to excavate and compact. Clay-heavy soils in parts of the hills foothills or older established suburbs like Morley can require deeper excavation, additional compaction passes and a thicker base layer of road base. Sloping blocks add cost because they need either extra fill or stepped formwork. If a concrete truck cannot park close to your site, pump hire adds roughly $600 to $900 to the job.

Reinforcement

A residential patio typically uses SL72 or SL82 steel mesh reinforcement laid on bar chairs before the pour. Larger slabs, areas with vehicle access or sites with reactive soil may need thicker mesh, a deeper slab (100mm vs 85mm) or the addition of steel fibres in the mix. These details matter because they affect long-term performance, not just upfront cost.

Concrete Mix Quality

We use premium concrete mixes from suppliers including Holcim and Boral. A 25 MPa mix is standard for a residential patio. A 32 MPa mix costs more but offers better durability and is worth specifying for high-traffic areas or patios that double as vehicle turning areas. Concrete quality is not somewhere to cut corners, particularly in Perth where summer heat and UV intensity put real stress on outdoor surfaces.

We see this regularly. A homeowner in Wanneroo or Joondalup accepts a very low quote, the slab goes down fast, and within two summers it has cracked, lifted or started flaking because the base was under-compacted or the mix was watered down on site. Fixing a failed patio slab means cutting it out and starting again, which costs more than doing it right the first time.

A few things a quality concreter should always do that cheap operators often skip:

• Compact the sub-base to at least 95% proctor density before laying road base
• Use a minimum 100mm depth of compacted road base under the slab
• Place control joints every 3 to 4 metres to manage cracking
• Apply a quality curing compound immediately after finishing to slow moisture loss in Perth's heat
• Allow a full 28 days before placing heavy furniture or pot plants on the surface

Our 5-star Google rating reflects the fact that clients consistently receive exactly what they were quoted, installed to a standard that lasts.

Timber decking costs a similar amount upfront but requires annual oiling or sealing and replacement of boards within 10 to 15 years. Pavers can shift and crack in sandy Perth soils without a very solid mortar bed. Concrete, poured correctly, lasts 30 to 50 years with minimal maintenance beyond an occasional pressure wash and reseal every 5 years or so. For total lifecycle cost, concrete is hard to beat in the Perth climate.

Perth gets over 3,000 hours of sunshine per year and summer ground temperatures can exceed 60 degrees Celsius on dark surfaces. Exposed aggregate is one of the best performers in this climate because the textured stone surface stays cooler underfoot than smooth concrete, provides natural slip resistance when wet, and holds its colour well under UV exposure. Lighter aggregate blends reflect more heat. Honed concrete is also durable but benefits from a penetrating sealer every 3 to 5 years to resist surface wear and staining from outdoor entertaining.

How much does a concrete patio cost in Perth?

For a standard residential patio in Perth, expect to pay between $65 and $150 per square metre depending on the finish. A plain grey broom-finished patio at 20 sqm runs roughly $1,300 to $1,800, while a 30 sqm exposed aggregate or honed concrete patio typically costs $3,300 to $5,500. Site conditions, access and concrete mix grade all affect the final number.

What concrete finish lasts longest in Perth's climate?

Both exposed aggregate and honed concrete perform very well in Perth's heat, UV intensity and coastal salt air. Exposed aggregate has the edge for outdoor patios because the textured surface stays cooler underfoot and does not require sealing as frequently. Honed concrete is excellent but needs a quality penetrating sealer applied every 3 to 5 years to maintain its surface. Either finish, poured with a 32 MPa mix, will comfortably last 30 years or more.

How long does a concrete patio take to install?

Most residential patios take one to two days for preparation and forming, with the pour itself completed in a single day. The concrete reaches foot-traffic strength after about 48 hours and full structural strength at 28 days. We recommend waiting the full 28 days before placing heavy outdoor furniture or pot plants. Total time from start to usable patio is typically two to four weeks depending on scheduling and weather conditions.

Do I need council approval for a concrete patio in Perth?

In most cases, no. Residential patios and outdoor entertaining areas in Perth generally fall within exempt development provisions under the Residential Design Codes of Western Australia. However, if your patio exceeds certain size thresholds, is located in a heritage area or attaches to a structure requiring a building permit, approval may be needed. We recommend checking with your local council before work begins, and we are happy to advise based on your specific suburb and project scope.
