It’s time to get those concrete slabs and start measuring the total volume of how much concrete you will need. Using a concrete calculator will give you an estimated cost on the amount of concrete you will need for the project. A concrete slab is very strong when done in our pour so to avoid running out of concrete you should use a concrete calculator.

It’s quite simple, you will need a tape measure, paper and pencil and a simple calculator. It’s important to know how much concrete will be used and concrete volume should also be taken into consideration. You definitely don’t want to be running to grab more concrete bags and realize you’ve ran out. The foundation slabs are strongest and will last much longer than concrete which was poured multiple times.

Same goes for foundation walls, it’s important to know the concrete required for your project, regardless if you’re making pool decks, driveways, setting posts, it’s important to calculate how much cement bags you will need to get all of the job done in one pouring.

There are also various options to choose from such as ready mixed concrete, footing concrete, bagged concrete, column concrete. Talking to a contractor will be your safest bet to know exactly what you need to use, but with this simple guide you will be your own concrete calculator and you will know the total concrete required.

How to Estimate Concrete in m3

Take measures. Put the tape measurer to use and write down the length, depth and width of the area. These measurements will give you the total cubic metres of area you have to work with. In order to calculate these dimensions into metres measure everything in metres or if you prefer centimetres, multiply the depth, width and length measures by 100.

Using this simple concrete calculator will help you measure the concrete volume and the concrete needed. The more information you are calculating and taking other factors into consideration the easier your job will be when you need to calculate how much concrete your project will consume.

Why Do You Measure Concrete?

Usually, a contractor will offer a concrete calculator and help you pick a specific concrete type for the job, and should help you determine all the materials required. It’s important to know the quantity required in estimate cubic meters because you want the pouring to be done in one go, not multiple.

The more times you pour the weaker the slab will be and this will lead to cracks. Take note that each volume of concrete will be different and not every concrete calculator can help tell you the amount of concrete needed for what you have planned.

How Do You Calculate Cubic Meters of Concrete?

Using a concrete calculator to calculate the total volume in cubic meters is quite easy. You will need to measure the length, width and depth for the area where you need to be pouring concrete. Once you have those overall lengths, if they are in centimeters then multiply each number by 100 to find the total amount in meters and then multiple those measurements together in order to get the total dimensions in cubic metres. Once you have the estimates you can determine how many bags you will need and how much material to get the required thickness.

How Much Concrete Do I Need for a 10mx10m Slab?

This is where a concrete calculator will come quite in handy. In order to fill up a 10 meter width by 10 meter length slab with the average depth of 10 cm you will approximately need 110 20kg concrete bags.

Keep in mind that in almost every example the volume covered by a standard 20kg bag is 1.1m square for an approximate depth of 10mm. It’s important to mix the content well and keep in mind that 2 litres of water per 20kg bag is the perfect ratio for mixing, which is best done in a wheel barrow.

How Much Does Concrete Cost Per Cubic Meter in Australia?

Depending on the total volume, which depends on the dimensions and overall thickness you could be expected to pay around $200 to $300 per cubic metre. Concreting can actually cost as low as $50 to $150 per square metre but once we take depth into consideration and add the width and length the cost will go up.

Having a proper calculator will help determine the volume of concrete needed. The cost in Australia can also increase if you decide to add some finishes like spray, use coloured concrete, decorative finish and similar.

The calculation after these additions can skyrocket but it will definitely be worth it when the project is complete. Most people use small slabs in order to get a better fit, especially if the quantity of work required isn’t too big.

It’s important to take into consideration the labour costs and type of concrete that will be used in order to for your calculator to give you the correct estimate. Make sure to calculate everything.
