Pool Excavation Volume Calculator
Calculate the total excavation volume required for a swimming pool, including working space clearance and over-dig allowance for forms and waterproofing.
Formulas Used
Average Depth:
davg = (Shallow Depth + Deep Depth) / 2
Excavation Depth:
dexcav = davg + Over-Dig Allowance
Excavation Footprint Area:
- Rectangular: A = (L + 2·Ws) × (W + 2·Ws)
- Circular: A = π × ((D/2) + Ws)²
- Oval / Elliptical: A = π × (a + Ws) × (b + Ws)
Where Ws = working space clearance, a = semi-major axis, b = semi-minor axis.
Net Excavation Volume (bank measure):
Vnet = A × dexcav
Hauled / Loose Volume:
Vhaul = Vnet × (1 + Swell% / 100)
