Estimates, not advice
The calculators give planning estimates based on the measurements you enter and typical material densities. They are not engineering, construction or professional advice. Material weight varies with moisture and compaction; depth recommendations are general. Confirm quantities with your supplier and, for structural work such as driveways, foundations and retaining walls, with a qualified contractor and your local building code.
