How Much Concrete to Order?


Whatever job you’ve got planned, it’s always important to order the correct quantity of materials.

That definitely applies where concrete is concerned.

Ask for too little, and you’ll have a temporarily unfinished job.

If the first batch sets before you have a chance to add the rest, you’ll end up with a seam in the finish known as a cold joint.

While this isn’t a problem for most jobs, it isn’t ideal for structural applications.

Order too much concrete, and you’ll end up spending more money than you needed.

It’s easy for costs to spiral beyond initial estimates, so if you have too much you’ll not only impact a project’s budget, but may also have to pay for the surplus to be disposed of safely.

First, let’s define exactly what concrete is…

What is concrete?

Concrete is not the name of a particular material, rather it’s a mix of them.

Broken stone, cement, gravel and other materials are mixed with water which then hardens to form concrete.

The hardness and density of the product depends on what’s included.

Mixing different materials together results in a chemical reaction that causes the workable mixture to harden.

The ratio of water to cement matters, so too does the paste quality which needs to be free of empty spaces.

To successfully use concrete, you must know exactly the consistency you need, when it needs to be made, and how to store and apply it before it hardens.

It might sound like a complicated process, but a specialist like Goodmix can provide the specialist advice you need for a project.



How to calculate the metric volume of concrete you’ll need

If you’ve never used concrete before, judging what to order might seem like something of a minefield.

However, it’s a relatively straightforward process.

If the area that you’re looking to concrete is a regular square or rectangle, calculating the correct amount you require is fairly simple.

You need to measure the width, depth and length before multiplying them together.

If the space you’re looking to concrete is irregular, you’ll need to break it up into regular shapes and make individual calculations for each space.

Round, circular, prism and other irregular shapes are trickier to measure.

It’s important to ensure all the units of measurements you use are metric and uniform.

It might also be prudent to add an extra five to 10 per cent to ensure that you have enough.

Getting your order right

As well as knowing the volume of concrete you require, there are other factors you need to consider.

Concrete comes in a range of different types and densities.

Your choice will depend on the job.

Colours and texture can vary too, so you should have some idea about the finish you’d prefer before you order.

Those variations influence the price.


Concrete density

There are regulations that determine the density of concrete needed for different areas and building projects.

A house foundation, for instance, that only needs to withstand foot traffic doesn’t require the same density as a garage floor or a driveway.

If you are concreting a goods yard used on a daily basis by heavy vehicles, the density would need to be tough enough to cope.
