This calculator will provide you with an estimate of how much concrete sand, weed membrane and sub-base you will need for your paving project. As this is purely an estimate for perfectly level ground, we highly recommend seeking advice from a professional landscaper before buying any concrete sand or sub-base. We do not take any responsibility for excess materials.
How Do I Use The Calculator?
- Select from the drop down menu where the paving will be located: driveway, back garden or solid, level ground. Select solid, level ground if you're replacing existing paving and the sub-base is already in place.
- Enter the width and height in metres of the area you wish to pave, this will generate the area you need to pave in square metres. If you already know the area, skip the width and height and type that directly into the area box
- Once you've hit enter, you will then see an estimate of the concrete sand, weed membrane and sub-base you require. Click the buttons below each product to buy
