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
  • 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)

Unit Conversions:
1 CY = 27 CF  |  1 CF = 0.028317 m³
