Calculating How Much Concrete You Need?

Calculate much concrete you need with Empire Ready Mix's concrete calculator. Simply enter the length, width & depth of your covering.

Using Empire Ready Mix’s calculator, you will be able to work out exactly how much concrete you need for your project. Simply enter your measurements above & we can calculate exactly how much concrete you need.

We here Empire Ready Mix know that getting measurements for a covering can be a bit of a hassle. However, it is an essential step when laying concrete.

There often can be confusion if people haven’t been given measurements in the correct format. Whether that be in meters, centimeters, yards, feet or inches. Therefore, we have provided all of these options when you are calculating your volume.

Ready Mix Concrete is ideal for Larger Projects

If you have a large-scale job, you don’t want to be spending your time opening & mixing bag after bag of concrete by hand. Bagged concrete lends itself to your smaller scaled projects.

If you need concrete for large patio areas, driveways or foundations for a house, Ready Mix Concrete is the choice for you.

If you are not sure of how to calculate the volume of different shapes or the type of concrete that you need for a project, get in contact with one of our team today.

What steps to take when calculating how much concrete to order

Step 1: Measure the dimensions of the area you are looking to cover

You need to measure the dimensions of your job site before calculating how much concrete you'll need. Specifically, the concrete placement's length, width, and depth. You can measure the dimensions in metres, centimetres, yards, feet, or inches. (Our handy concrete calculator, lets you calculate, using any of these measurements.)

Step 2: Enter your measurements into our concrete calculator

Once you have this, simply enter your measurements for the length, width and depth of your site (ensure that you are using the right units), and click ‘Submit’.

Step 3: Once you have calculated the concrete you need to get a quote

Once you have calculated how much concrete you need, get in contact with our team for a quote. This will give you the cost of the concrete, as well as how much delivery to the site of your project will cost.

We are happy to offer you a quote for our concrete & delivery for free. There is no obligation to order.

Also, if you place an order & your needs change, you can adjust the volume of concrete you’ve purchased. Just give one of the Empire Ready Mix team a call & we will be delighted to help.

Concrete Calculator - FAQ's 

What if I order the wrong amount?

If you order too much or too little concrete for your project, we can easily adjust your order over the telephone beforehand, just contact us beforehand & we can make the necessary amendments.

When using Ready-mix concrete, you normally have to pre-order a volume for us to batch, this can be done in several ways.

On large quantities over 16m³ where it is very hard to accurately work out a fixed volume due to awkward shapes or uneven foundations we would recommend you order concrete to the nearest cubic meter in 6m³ and 8m³ increments with a 'Plus load', this means you would receive 16m3 on concrete and you can then work out the balance required for us send a 'makeup load'.

What type of concrete do I need?

Concrete is needed for a range of different purposes, foundations, flooring & walls, just to name a few. However, not every concrete mix is the same.

Concrete is made up of cement, water, as well as a mixture of sand & stone, but each of our unique mixes contains a number of different materials that offer different qualities.

The different grades of concrete identify their varying strengths. The nature of the project & the load the concrete will need to take, will ultimately identify the grade of concrete you need. The typical grades range from C10 to C40 grade concrete.

We understand that deciding what grade of concrete to use can be difficult. We created this page as a general guide to some of the most popular concrete mixes. We offer a large variety of concrete mixes, tailored exactly to our client's specifications, whether that be domestic or commercial. We do a lot more specialised and specific mixes so please get in touch with any queries!

Still Need assistance?

It is important to recognise that concrete is used in a variety of different situations. Not every surface is flat or a perfect square/rectangle.

You may need assistance when it comes to calculating for a range of structures, including square slabs, footings, round slabs, columns, stairs and fence post holes.

The experienced Empire Ready Mix team is here to help you calculate the correct amount of concrete that you need for your individual projects. Whether you’re building a residential development or you just need it for some DIY, we can provide you with a quick and effective concrete calculation service.

Whatever type of measurement you prefer to work in we will provide you with a breakdown of how much you need and how much it will cost. If you have any questions about our concrete calculations please get in touch with us today.

Concrete Volume Tips & Formulas For Different Concrete Shapes

Square Slab:

Volume in Cubic Feet (f) = Width x Length x Depth

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

 

Round Slab:

Area of the Circle (ft³) = Pi x (Diameter/2)^2

Volume in Cubic Feet (ft³) = Depth x Area

 

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

Pi = 3.14

 

Wall:

Volume in Cubic Feet (ft³) = Thickness x Length x Height

 

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

 

Round Column:

Area of the Circle (ft³) = Pi x (Diameter/2)^2

 

Volume in Cubic Feet (ft3) = Height x Area

 

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

Pi = 3.14

 

Steps:

The number of steps is the total number of steps including the platform.

 

It is important to calculate the volume in sections from the ground to the top of each section.

 

Volume in Cubic Feet Under Platform =

Platform Depth x (Rise Height x Number of Steps) x Width

Counting steps starting at the bottom step and not including the platform we'll have Step1, Step 2, Step 3, etc.

 

Volume in Cubic Feet Under Each Step =

Run Depth x (Rise Height x Step Number) x Width

 

Add together the total step volumes

The total concrete you need is:

Volume in Cubic Feet = Volume in Cubic Feet Under Platform + Volume in Cubic Feet Under Steps

 

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft3) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft3) x 0.0283
