When to use the gravel tool
The Gravel tool is built for practical concrete and masonry planning. It helps estimate gravel coverage for driveways, drainage, base layers, paths, and landscaping, while keeping the calculation tied to the actual work rather than a generic remodel assumption.
It is most useful when the project is still being shaped: measurements are close but not final, product grades are not fully selected, and the homeowner wants a clearer brief before comparing suppliers, materials, service companies, or contractor quotes.
