FAQ’s


The addition of oxides to normal concrete is common practise for any concrete delivery, but usually at the laying stage.

The colouring of concrete has to be done by arrangement as normally the colour is added at the screeding stage, not in the mixer. The selection of colour is at the discretion of the customer, given the batching nature of the mix cycle there is no guarantee of colour consistency from Concrete Taxi when inserted to each mix.

On the delivery day, you can make payments to our operators, by Visa, MasterCard, eftpos or cash.

The mix on site format and the pay for what you use system makes it easier for on site payment. Credit card details can be given to the Office for processing. The operators have a mobile eftpos machine, allowing for greater flexibility in payment.

We can be contacted directly by e-mail, telephone to 1300 880 955, fax or in writing.

For full contact details, please see our contacts page. The 1300 number is attended 7:00am to 6:00pm (EST) Monday to Friday and 7.00am to 2.00pm Saturday, with an answering and return system in place all other hours.

The chemical reaction that takes place within a concrete mix begins as soon as the cement and water are mixed together. The onsite mixing process allows for variation in the mix consistency to allow for particular site conditions.

This means that usually, you will have between 2-3 hours once the concrete arrives on your job to place, level, compact and finish the mix.

The normal rate of production for a Concrete Taxi is for .8 cubic metres per hour (12 wheelbarrows). The driver will discuss the level of workability you require as this can be varied on site. The addition of a rapid set agent is possible at an additional cost.

Concrete quantities, like any other measure of volume, are calculated by multiplying length x width x depth (or height) and are measured in cubic metres (m3).

For example: If a room measures 3m x 4m and the depth of the concrete floor is to be 100mm, the calculation is 3 x 4 x 0.1 = 1.2m3. Make sure that you work out your sum in the same units (don’t mix metres and millimetres or yards and feet), and bear in mind that it’s generally easier to work with the metric system. A concrete calculator for slabs and holes is included on many of the pages on our website. Click Here to use the calculator

One cubic metre of concrete weighs around 2.4 tonnes.

With 15 wheelbarrows to a cubic metre, that equates to 160kg per barrow load.

You will only pay for the concrete you use. A pricing structure covers any job between 0.1 and 2 cubic metres and for deliveries 24/7.
Delivery zones and hours of delivery will affect the final cost.

Please contact our Customer service team for further information on 1300 880 955.

The “pay for what you use” epithet is balanced by the need for on site productivity. The charges for waiting time or after-hours deliveries are clearly spelt out in our pricing structure, which can be e-mailed or faxed.

Generally 24 hours notice is required, night and weekend orders usually need sorting at the earliest due to scheduling issues.

Orders can be placed by telephone contact with the office, a specific delivery time will be advised. The truck operators will contact you on the day if they are running early or late to allow for on site co-ordination.

For concrete bases, floors and drives, the area should be dug out to the required depth of concrete a minimum of 100mm or 4 inches is advisable and the soil should be compacted as required.

In clay based soil areas a sub-base layer of hardcore should be placed and compacted to give the concrete a solid base and prevent sinking. A thin layer of sand on top of the hardcore will provide a smooth surface to work from and make calculation of the quantity required easier as it will help to prevent variations in the depth.

If you use a layer of polythene damp proof membrane between the sub-base and concrete, it will assist in preventing your concrete from drying too quickly, and help to stop problems with rising damp on your finished project. The membrane is recommended for all habitable areas, usually not used for sheds or driveways

When the truck-mixer arrives, the driver will assess the required delivery location, and discuss with you the best method of discharging the concrete.

Given the small amounts of concrete involved, the normal method of discharge is into wheelbarrows (we carry two on board for your use). The mixing process sees the Concrete Taxi produce two wheelbarow loads of concrete every six minutes, allowing ample time for you to wheel and lay through the mixing cycle. The standard production rate is for .8cu.m/hour (12 wheelbarrows), if on site delays are incurred an additional charge may be applied.

Most people will already have the tools required to handle and place concrete, but check the list below to make sure that you are fully prepared.

Wheelbarrow – we have 2 on board for the customer to use;

Shovel and Rake – For moving the concrete;

Spirit level – To ensure accuracy;

Tape measure – For calculation of quantity required;

Timber – To make pegs, formwork, and tamping beam;

String and pegs – For setting out the area to be concreted;

Trowel or float – For surface finishing;

Brush – For cleaning up afterwards.

Please be aware that concrete is both abrasive and alkaline, so protective clothing, gloves, boots, overalls etc. should always be worn. Cement can burn skin.

We are able to access most areas, as our normal method of delivery is to discharge the concrete into wheelbarrows (we carry two on board for your use)

The dimensions of a truck-mixer are as follows:

Length = 6.3m (21′)

Width = 2.2m (7′) Minimum access= 2.4m

Height = 2.5m (8′)

Weight = 10.4 tonnes

Chute length = 1.5m (5′) – see text below

Capacity = 2m3 maximum

Please ensure that you can provide safe and reasonable access for the truck-mixer, as we cannot be held responsible for damage caused to footpaths, existing driveways etc.

Normal discharge point is at the roadside, entry to the site is solely at the discretion of the operator and the responsibility of the customer. You may be asked to sign an indemnity form at the time of delivery. If the truck gets bogged due to soil conditions accessed at your request/direction, you will be liable for recovery costs (approx. $400 is typical).

Assuming that the truck can position itself at right angles to the job, the chutes have a maximum reach of approximately 1.5m or 5ft. The end of the chute reaches to 1 m. (3′) high at point of discharge.

That depends on what sort of job you’re doing. Different mix specifications are used for different purposes with higher-grade (strength) mixes being used for foundations as compared to slabs and walkways.
Council will quite often have recommended/required strengths suitable for local soil conditions so contact the Building Department for advice or check their website before commencing the work.
