Previously, we talked about the cost of formwork, which mainly covers the cost of concrete per square meter.
But what about the cubic meter?
Concrete is charged per cubic meter as before it sets and hardens, concrete is a fluid – although it is more of a variety. So calculating m3 is equal to its volume.
To calculate this, multiply the height, length, and width of the board.
A cubic meter equals 1000 liters.
What variables can affect the price of concrete per cubic meter?
Many factors can affect concrete pricing. This can include the time it takes to excavate and level the area to accommodate the concrete. Drainage required is another, as is ease of access.
If work has to be done on a busy road, traffic controllers may be required, which greatly increases labor costs.
Concrete used in a driveway may cost more than a slab or driveway.
If old concrete needs to be removed, this cost should be budgeted appropriately.
How much does concrete cost per cubic meter?
In Australia, the average cost of concrete can range from $200 to $300 per cubic metre.
However, this can cost as much as $350 for 40 MPa strength, which is commonly used for feet, tracks, anchor posts, panels, and other high-strength items.
On the other end of the spectrum, cheaper variants can cost around $160 per cubic meter. Concrete usually costs more per cubic meter when purchased in smaller quantities.
A standard 20″ x 20″ slab typically costs between $1,340 to $2,400.
A 12-by-12-foot concrete slab costs about $185 to $865 to have it laid by a concrete worker. The cost of a 12 square meter concrete slab is about $600 to $600
Costs can vary due to different local rates. The type of concrete required and any admixtures or additives required can also make a difference. However, larger jobs or if you are required to order concrete regularly can also attract discounts.
Common formwork jobs around the home include swimming pools, driveways, footpaths, foundations, walls, slabs, kitchen counter tops, and building foundations.
How to hire a professional concrete worker
Although many individuals are able to lay a small slab themselves—there are plenty of guides, tutorials, and videos online that demonstrate the process—larger jobs will likely need the equipment and experience of a professional concrete.
Licenses are regulated on a state/territory basis. Every Bar of Tasmania and the Northern Territory requires a dedicated concrete or masonry licence.
When it comes time to get quotes—for most jobs, three or so are recommended—there are a host of questions you should ask your concrete worker.
- What license(s) do you hold?
- Do you currently have valid insurance?
- Can you provide me with a written quote?
- Do you have references?
Due to the presence of social media, many concrete workers have a library of past projects online. This would be an especially great idea if you are looking for a concrete worker for a more complex role.
