Before you order
Use measured dimensions and supplier values

Material depth should describe the finished compacted layer unless the calculator specifically asks for loose depth.
Confirm density and packaging
Local mixes, aggregate types, bag sizes and truck capacities vary. Replace defaults with values from the supplier quote.
