Concrete strength can range from 15mpa to 80mpa, so narrowing down what you need is the most important step. The industry standards are a good place to start:
- 20mpa & 25mpa is most commonly used for House slabs, Foundations, Driveways and Footpaths.
- 32mpa & 40mpa is most commonly used for Suspended Slabs, Car Parks or high volume vehicle traffic areas.
- 50mpa and above are designed and requested by engineers for high rise buildings and other special applications.
You can also choose the aggregate which is available in 10mm and 20mm, depending on your project.
- Preventing "Slump"
Right Product for The Right Job
Slump refers to the measurement of wetness and workability of your concrete when delivered to site. Standard slump for most companies is 80, and is most commonly used in the industry. Choosing the right slump for the job ensures that any later issues are avoided, such as uneven pouring, excessive drying times and premature cracking. We supply mixes that range from 20 slump to 220 slump and this can be changed at your request to match your building plans or to match the advice of the professionals onsite.

Exposed Mixes & Coloured Concrete
Coloured concrete and Exposed mixes are a great way to add life and dimension to any pour. Our industry leading suppliers have a variety of options at your disposal. To see the range for yourself, check out our colour chart from Concrete Colour Systems here and our exposed range from Holcim Australia here.
Slabs
Slabs are most common and have two variants; conventional slabs which are dug into the natural ground, and waffle pod slabs which sit above ground. Concrete strength for slabs are dependent on the engineer specifications, and what its main use will be post-pour.
Block, Wall & Dincel Mixes
These mixes are used to fill special brickwork or to add extra strength to preformed retaining walls. Similarly, strength is dependent on its use, most commonly between 20mpa and 40mpa and this mix will use a 10mm stone to ensure its easily pumped. These mixes have a higher slump, starting from 120mm as to meet regulation requirements for air pockets.
Spray Mixes
Shotcreting is commonly used for swimming pools, retaining walls, and embankment. These mixes are pumped through a spray pump with a compressed airline to make it similar to a hose. These mixes are standard 70 slump and generally range between 20mpa-40mpa.
Footings & Piers
Footings and piers act as the base for any work and provide extra strength for things to be built on top. These mixes are generally 20-25mpa and poured into a pre-dug trench.
Stabilised Sand
Sand is used when a compacted or especially hard fill is required, such as backfilling trenches over pipes. These mixes come in ratios ranging from 1:6 – 1:24, dependant on what you need.
No Fines Concrete
No Fines mixes are used in areas with high water flow to allow for drainage. These are commonly used around trees or garden ares or behind retaining walls.
