Top 3 concrete calculators

Measuring the volumes of concrete needed for any job can be a tricky process and it is something that you need to be very accurate with!

No-one wants to have their slab or footings poured and still have a half-full truck sitting out the front. You’ll either need to pay for them to take it back, find a hole for it or dump it in the skip (the skip company aren’t going to be happy)

You equally don’t want to be left a little short, this is just the worst, I’ve done it once before. 

To ensure I get the quote and order right, here is a look at 3 simple tools that I use. They all have different purposes, let’s dive in. -

If you have dug the foundations & finished the form-work on-site, this is a really great tool to get the volumes you need or to cross-check against your initial quote to make sure you are ordering the right amount. Just enter your measurements from site and this will give you the volumes you need. 

Tip: Always ensure you allow a % for wastage, I am comfortable with the accuracy of my measurements so I allow approximately 5% on most jobs.
