Your Guide to Smart Concrete Costs in Australia
Determining the cost of concrete per cubic metre is critical for individuals and businesses involved in construction and building projects. Concrete is a fundamental material used in various structures, from residential footings and slabs to commercial buildings and infrastructure projects. The price for a cubic metre of concrete typically varies between AUD 200 and AUD 300. However, this can increase to AUD 350 for high-strength mixes rated 40 MPa. Factors influencing the cost include the grade of concrete required, local pricing differences, and the addition of any admixtures or additives necessary for specific construction needs.
The cost of ready mix concrete is expected to fluctuate depending on numerous factors. These can range from the complexity of the project to the accessibility of the site, which may demand specialised delivery services such as pump hire. Moreover, mixed onsite concrete opportunities available in specific locations can provide savings by ensuring no excess material goes to waste, with clients paying only for the concrete they use. With the ever-changing nature of the market and material costs, current estimates should be sought to prepare for accurate budgeting in construction projects.
Key Takeaways
- A cubic metre of concrete in Australia typically ranges from $200 to $300. Still, it can be influenced by location, concrete grade, and special additives.
- Concrete strength (measured in MPa) is a significant cost factor – higher-strength concrete commands a higher price.
- Consider labour costs, delivery or pump hire fees, and additional expenses (like formwork) for a realistic budget.
- Hiring a qualified, licensed concreter ensures expert workmanship and adherence to Australian standards.
- Factor in potential logistical challenges, the cost of special finishes, and hidden expenses for the most accurate price estimate.
Understanding Concrete Measurements
When measuring concrete, accuracy is paramount. One must be mindful of the units used and the method employed to calculate the volume to ensure correct material quantities.
Units of Measurement
Concrete is commonly sold in cubic metres (m³). This measurement unit represents a cube’s volume with sides of one metre in length. Precise conversion from other units of measurement to cubic metres is crucial for accurate concrete order placement. Since concrete is also measured using square metres (m²) for area coverage, it’s important to distinguish that square metres refer to area while cubic metres pertain to volume.
Calculating Volume
Calculating the volume of concrete needed for a project requires three measurements:
- Length (metres)
- Width (metres)
- Depth (metres)
These dimensions are multiplied together:
Length x Width x Depth = Volume in cubic metres
To better illustrate this, consider the following example: For a slab that is 6 metres long, 4 metres wide, and 0.15 metres deep, the volume calculation would be:
| Length (m) | Width (m) | Depth (m) | Volume (m³) |
| 6 | 4 | 0.15 | 3.6 |
It is also essential to consider additional considerations, such as the potential need for slightly more concrete due to spillage or minor miscalculations.

Factors Influencing the Cost of Concrete
The cost of concrete is subject to various factors, ranging from the grade of concrete required for the project to the complexity of the work involved in its placement.
Concrete Strength and Composition
The strength and composition of concrete are key determinants in its pricing. Concrete is classified by its MPa strength, with a higher MPa indicative of stronger concrete that can bear more weight and stress. This increased strength typically comes at a higher cost. For instance, concrete needed for structural foundations requires a higher MPa, reflecting a price range from $200 to $300 per cubic metre.
Cement, additives, and admixtures enhance concrete properties such as drying time, durability, and workability. The inclusion of these materials can alter the price significantly. Additives for faster drying or admixtures for additional waterproofing will contribute to increased costs.
Labour and Concreting Process
The labour and concreting process also play substantial roles in determining overall costs. Labour costs can vary widely, influenced by the worksite’s geography, the job’s complexity, and prevailing market rates. If concrete is delivered and poured, or if it is mixed onsite and then poured, the costs will reflect the man-hours and expertise required. Skilled labourers are essential for mixing and laying concrete effectively, and their compensation is factored into the final price.
Additionally, the extent of the project — whether a small home renovation or a large-scale commercial development — impacts the amount of concrete required and the associated labour costs. More extensive projects could attract discounts due to the bulk nature of the work, while smaller jobs may incur a standard rate.
Concrete in Construction and Renovation
Concrete plays a pivotal role in both construction and renovation projects across Australia. Its unparalleled durability and versatility make concrete integral for foundations and pathways.
House Slabs and Foundations
When discussing concrete foundations and house slabs, one refers to the robust platform on which homes are built. A concrete slab serves as the primary support for the structure, ensuring stability and resistance to environmental forces. In Australia, the quality and precise engineering of this concrete determines the durability of the residential structure. Factors such as soil type and weather conditions influence the concrete mix and thickness of the slab, making expert consultation a necessity.
Driveways and Pathways
For their functionality and aesthetic appeal, concrete driveways and pathways are prevalent in Australian homes. A driveaway must withstand the weight of vehicles and frequent traffic, with concrete being the preferred choice for its long lifespan and low maintenance. Furthermore, concrete footpaths provide safe and durable surfaces for pedestrian use. The design of these concreting projects can vary to include different textures or colours, allowing them to blend seamlessly with the property’s design.
Aesthetic Options and Finishes
Visual appeal is just as crucial as functional strength when considering concrete for a project. This section will outline the aesthetic choices available, mainly focusing on surface texture, colour variations, and unique additions like aggregate or stencilling effects.
Surface Textures and Colours
Exposed aggregate is a sought-after finish that involves stripping away the surface layer to reveal the colourful stones within the concrete mix. It offers not only aesthetic appeal with its varied textures and rich tapestry of hues but also provides a durable, skid-resistant surface. Coloured concrete, on the other hand, transforms conventional grey into vibrant shades using pigments, enriching spaces with custom design themes.
Preferred Textures and Colours:
- Exposed aggregate finish: Robust look featuring a blend of natural stone.
- Coloured options: Broad spectrum ranging from subtle earth tones to bold, vivid colours.
Stencilled concrete brings the creative vision to the surface, allowing for bespoke patterns that mimic brick, stone, or wood. The decorative stencilled finish can be particularly striking, offering texture and depth that add character to a plain surface.
Special Additions
For those looking to take the aesthetic aspect a step further, consider polished concrete—the method of choice for a sleek, high-gloss finish that is both elegant and easy to maintain. It suits interior spaces exceptionally well and can elevate the atmosphere of a room immensely.
Noteworthy Finishes:
- Polished: Gleaming surface that reflects light and adds spatial brightness.
- Decorative stencilled: Custom designs and textures that stand out with artistic flair.
While exploring the types of finishes, decorative concrete emerges as an umbrella term that encapsulates various options, including both exposed aggregate and stencilled techniques. These finishes can significantly enhance the visual interest and can be tailored to the specific needs and style preferences of any project.
Hiring a Professional Concreter
When it comes to laying concrete, engaging a professional concreter can ensure the project is carried out neatly and up to the relevant Australian standards. They provide expertise, proper material handling, and peace of mind regarding the work’s structural integrity.
Quotation and Costs
Written Quote: A detailed written quote from a professional concreter should clearly outline all anticipated costs. This is a legally binding agreement between the homeowner and the concreter that stipulates the price and scope of the work. Quotes should include:
- Material Costs: Concrete price per m3 and additional fees for required admixtures.
- Labor Costs: The hourly or square metre rate charged by the concreter, which, in Australia, can range from $25 to $60 per square metre.
Insurance: Ensure that the concrete provides evidence of their insurance policy. This protects against any unforeseen incidents that may occur onsite during the concrete laying.
References: Requesting references from former clients can provide insight into a concreter’s work ethic and job quality.
Ensuring Quality
Licensed Tradie: Hiring a licensed tradie is paramount. It’s a clear indicator that they have met industry standards and regulations.
- Evidence of licensing
- Training and qualifications possessed by the concrete
- Membership in professional bodies such as the Master Builders Association
Warranty: A quality concreter should provide a warranty for their work, ensuring that any issues within this period can be resolved without additional cost.
By ensuring these elements are in place, clients can feel confident that their concrete will be laid professionally and with high-quality results.

Additional Expenses and Considerations
When assessing the cost of concrete per cubic metre, one must be mindful of various additional financial considerations. These include logistical challenges and hidden costs that can significantly affect the final price.
Challenges and Logistics
Projects may encounter logistical issues, which can add to the overall cost. Access to the site, for example, can significantly influence the price; restricted access might necessitate smaller delivery trucks or additional handling to transport the concrete. One must also consider the complexities of the ground and levelling. If the terrain is uneven or requires extensive preparation, this will entail further labour and contribute to the total expense.
- Variables such as distance from the supplier and ease of access for heavy vehicles could impact delivery fees.
- Formwork, the temporary moulds into which concrete is poured, is essential for accurate and professional project completion. Secure and efficient concrete formwork is critical, especially when creating structural elements such as footings, and can be expensive depending on the structure’s complexity.
Hidden Costs
Below the surface of straightforward material costs lie potential extras that, if not budgeted for, may cause financial strain. The local prices of concrete and related materials vary geographically and fluctuate with market changes, so one must stay updated on current rates in their region.
- Additional elements that could affect the cost include special finishes or the inclusion of admixtures to enhance or modify the properties of the concrete.
- If revisions to the original plan are required, or if unanticipated variables such as soil stability come into play, this will necessitate adjustments in labour and materials that can result in higher expenses.
- Preparatory work such as levelling the site, clearing vegetation, or any necessary grading should be accounted for, as these are commonly overlooked in initial quotations.
Parting Thoughts
While initial cubic metre pricing may seem straightforward, concrete projects involve many variables. Remember to consider the value of meticulous planning and careful budgeting.
