Sand Calculator

Calculate the volume, weight and number of 25 kg bags of sand needed for a given area and depth, using a typical dry-sand density.

Calculate the volume and weight of crushed stone, gravel base, river rock or limestone needed for an area, by material-specific density.

Calculate the loose gravel base volume to order for a target compacted depth, accounting for compaction shrinkage, plus estimated weight.

Calculate the number of retaining wall blocks, cap units, base gravel and drainage backfill needed from wall length, height and block size.

Calculate the gravel volume and weight needed for a French drain trench, accounting for the volume displaced by the drain pipe.

Estimate gravel tonnage for a two-layer driveway: compacted dense-grade base plus surface gravel. Reports tonnes per layer, total volume and area.

Convert rise and run into grade percentage, slope angle in degrees, a 1:n ratio and the slope length. Standard rise-over-run conversions.
