Gravel Yardage Pro: an aggregate calculator suite
A free collection of calculators and references for estimating gravel quantities, costs, loads, and materials for projects from driveways to French drains.
- For
- Homeowners and contractors planning aggregate projects
- Worth noticing
- Its reference tools include a visual chart comparing eight stone types against a US quarter and a quarry scale-ticket feature.
Field notes
The suite separates estimates by task and material, with examples such as a French-drain calculator that accounts for four- or six-inch perforated pipe and a retaining-wall backfill tool citing NCMA guidance. A master calculator lists three footprint shapes, while the reference area includes a state-by-state price and frost-line directory. Regional per-ton prices are displayed as examples; the extract does not establish how those figures are sourced or updated.
