Use the aggregate and concrete calculators to determine how much material you need:
‣ Aggregates calculator
To calculate how much aggregate you need to order, simply enter the dimensions of the area you are filling. Different aggregates have different densities, so please make sure you have chosen the correct aggregate type. You can use imperial, metric or a combination of both by using the drop down boxes.
The exact conversion will depend on a number of factors beyond our control, for example moisture, method and degree of compaction, type of sub–base, etc. We cannot be held contractually responsible for any surplus or shortfall found on site.

‣ Concrete calculator
You can use this calculator to work out how concrete you need.
