About this tool

Choose brick or concrete. For a wall, enter its length and height and whether it is half-brick (115 mm) or full-brick (230 mm) thick. For a slab, enter length, width and thickness. A waste allowance is added. The concrete uses a 1:1.5:3 mix (M20), with a 50 kg cement bag.

When to use it

Estimate bricks for a wall or cement, sand and aggregate for concrete.

Tips

Add 5 to 10 percent for waste. Check the mix ratio for your use.
