Getting Your Concrete Quantity Right

Nothing's worse than running out of concrete halfway through a pour. Or worse - ordering too much and paying for disposal. Our calculator helps you hit that sweet spot. Remember to add 10% extra for waste, spillage, and variations in ground level. Professional contractors always do this - it's not being wasteful, it's being realistic.

🏠

M20 (1:1.5:3)

🏭

M25 (1:1:2)

Commercial buildings, bridges. Stronger, used for heavy loads.

🚧

M15 (1:2:4)

Footings, boundary walls, non-structural. Lower strength, cheaper.
