Which one do you need?
- Concrete Slab Calculator
- Work out the concrete for any slab in cubic yards, cubic feet, cubic meters and 80 lb bags. Add a waste allowance and get the exact amount to order.
- Concrete Footing Calculator
- Calculate concrete for continuous strip footings and isolated spread pads in cubic yards and cubic meters, with waste allowance and volume per lineal foot.
- Concrete Bag Calculator
- Find how many bags of concrete you need for a slab, post hole or known volume, using published bag yields, plus dry weight, mixing water and total cost.
- Concrete Column & Sonotube Calculator
- Work out concrete for round Sonotube piers or square columns: volume per column, total cubic yards, 60 and 80 lb bag counts, and an order figure with waste.
- Concrete Stairs Calculator
- Find the concrete volume for poured steps from rise, run, width and step count, including the sloped throat slab, plus bag counts and form board lengths.
- Concrete Mix Ratio Calculator (Cement, Sand & Aggregate)
- Split a concrete volume into cement bags, sand, coarse aggregate and mixing water for any nominal mix ratio, with the 1.54 dry-volume factor applied for you.
