Paver Base and Bedding Sand Calculator
Calculate compacted base aggregate and bedding sand volumes for a paved patio, drive or path.
Formula
V₁ = Length × Width × Compacted base depth/100 × (1+Waste allowance/100); V₂ = Length × Width × Bedding sand depth/100 × (1+Waste allowance/100)
Planning estimate. Check product specifications and local requirements before purchasing.
