build.procure-concrete-pour Calculator
Calculates cubic yards of concrete needed for a slab or footing from dimensions, adds a 10% waste factor, and estimates mix bags or ready-mix truck loads. Ordering too little stops a pour mid-slab and creates a cold joint — a structural defect.
Inputs
L
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
W
Horizontal extent perpendicular to the length.
D
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Waste
A multiplier applied in the calculation.
Results
cubic feet
Volume in cubic feet. 1 cubic foot = 28.3 litres = 7.48 US gallons.
cubic yards
Volume in cubic yards. 1 cubic yard = 27 cubic feet = 764.6 litres. Common for concrete and bulk material ordering.
cubic meters
Reference formula or conversion factor shown for context.
with waste factor
A dimensionless multiplier applied in the calculation.
