Premixed concrete is supplied in standard strength grades of 20mpa, 25mpa, 32mpa, 40mpa and 50mpa. For most domestic projects, including floor slabs, paths and sheds, concrete having a strength grade of 20 is the minimum that should be used. 25mpa is preferable for driveways, heavily trafficked paths and patios. 32mpa is traditionally used on applications where more strength is required like suspended slabs and large carparks. 40mpa and 50mpa are generally used in the construction of high rise buildings.
If you're unsure our industry experienced staff will be able to point you in the right direction and let you know what type of concrete mix will best suite your application.
You place the concrete order with Concrete Booking Agency, we then source the concrete for you from one of our suppliers. Once we have ordered your concrete we call you back and confirm the order. At this point we require your email address and credit card details for payment. Upon payment in full an invoice is emailed and then we confirm your concrete order.

The truck has an unloading time of 30 minutes, any time that the truck is onsite after this time will incur waiting time charges. Waiting time is charged at $2.00 per minute + GST. You will be notified of any additional charges incurred prior to us charging your credit card.
The most common placement method is by chute from the rear of the concrete truck. Wheelbarrows are also a common way but can be time consuming and waiting time is sometime inevitable. Concrete pumps are a cleaner, faster and more efficient way of moving the concrete to where required, especially in place where a wheel barrow simply can't get to, but there are additional costs involved.
Yes you can ! If you send back less then 1.0m3 of concrete there is no additional charges. Any returned concrete over 1.0m3 will incur additional charges. Depending on which supplier we use but the returned concrete over 1.0m3 will be charged out at price of $200 per m3+ GST for the total amount returned. You will be notified of any additional charges incurred prior to us charging your credit card.
Slump is a measurement of the workability of the concrete. For example, concrete with a 100 mm slump is easily workable while concrete with a 40 mm slump is fairly stiff and much harder to work. For most work around the home, order an 80 mm slump concrete. When filling cavity walls and blockwork the slump is increased to 120 mm allowing for the concrete to flow better. The addition of water added to the concrete onsite will weaken the concrete.
20 mm rock is the most common size and suitable for most applications. For most paving applications 14 mm provides more workability and is preferred by many concreters and home handymen. 7 mm aggregate is used when filling cavity walls and block work.
