Calculator
Estimate concrete volume in cubic metres for slabs, foundations, beams, and columns. Use the result to plan ready mix orders and material procurement for Zanzibar construction projects.
Instant estimate
Concrete volume
Useful for slab, foundation, and ready mix concrete quotation planning.
Planning estimate only. Zanzibaba can review your BOQ before material supply coordination.
How to Calculate
Volume = Length × Width × Thickness
Multiply the length, width, and thickness (or depth) of the area to be poured to get the volume in cubic metres. Add a waste factor of 5–10% for spillage, uneven ground, and formwork tolerances.
Example
A 10 m × 8 m slab at 0.15 m thick = 12 m³
With 10% waste
12 × 1.10 = 13.2 m³
Units
Enter all dimensions in metres for consistent m³ output.
