How to Calculate
Foundation Concrete Formula
Volume = Foundation Length × Width × Depth
Measure the full length, width, and depth of the foundation trench or formwork. For strip foundations, multiply the trench length by the width and depth of the concrete pour. For pad foundations, calculate each pad separately and sum the volumes. Always include a 5–10% waste factor for spillage and ground irregularities.
Strip foundation
20 m × 0.6 m × 0.3 m = 3.6 m³
Pad foundation
1.2 m × 1.2 m × 0.5 m = 0.72 m³ per pad
Multiple pads
Sum individual pad volumes for total foundation concrete.
