Trench Volume & Bedding Calculator

Calculate the bedding stone needed for a trench: volume in cubic yards and tons of #57 stone with a 10% waste factor.

Results

Enter your dimensions and hit Calculate.

This is a quantity estimate for pricing and ordering. Bedding spec (depth, gradation) is set by the pipe manufacturer and local code — do not use this to select the spec.

Assumptions

  • #57 stone density: 1.45 t/yd³ (typical crushed limestone bedding). Different aggregate will shift tonnage.
  • 10% waste factor accounts for over-dig, spillage, and trench irregularities.
  • Tonnage is ceiling-rounded — bedding stone ships by the ton.
