Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Pipe-zone volume = trench length × width × (bedding depth + surround height). Pipe cylinder volume is subtracted. Waste is added, then weight, truckloads and cost are estimated.

FAQ
Trench Bedding Material Calculator questions
Why subtract pipe volume?+
The pipe occupies part of the trench zone, so it displaces bedding or surround material.
Is bedding depth the same for every pipe?+
No. Pipe material, diameter, soil, load and project specifications determine the required bedding detail.
Why can actual truckloads differ?+
Trucks may be limited by weight before volume, and loose bulk density changes with moisture and aggregate type.
