Calculate Concrete Needed for Your Project
Typical: 10-15 cm for slabs, 30+ cm for foundations
Typically 5-10% for spillage
How to Use
1
Measure Area
Enter length and width in meters.
2
Set Thickness
Input slab thickness in centimeters.
3
Add Wastage
Include 5-10% for spillage and uneven surfaces.
4
Calculate
Get total concrete volume needed in cubic meters.
Concrete Calculator Guide
Formula
Volume (m³) = Length × Width × Thickness × (1 + Wastage%)
Concrete Mix Ratios
- 1:2:3 - General purpose (1 cement : 2 sand : 3 gravel)
- 1:2:4 - Foundations and footings
- 1:1.5:3 - High strength (columns, beams)
Typical Thicknesses
- 10 cm: Pathways, light slabs
- 15 cm: Driveways, garage floors
- 20-30 cm: Heavy-duty slabs
- 30+ cm: Foundations, footings
