How this was calculated
Formula source(s)
- Typical bulk density used here: approximately 1.4 short tons per cubic yard
- Density varies with moisture, grading and how the material was processed
Inputs used
- Rip Rap volume (yd³)
- 10
Intermediate steps
- Conversion factor applied
- 1.4 short tons per yd³
Confidence note: About 1.4 short tons per cubic yard for graded rip rap; large angular stone leaves substantial voids. A planning figure, not a specification. Confirm the figure with your supplier or waste contractor before relying on it.
What this calculation does not cover
- The tonnage here is a load total, not a handling figure. At the larger gradings rip rap is placed a stone at a time, and one piece can be a machine lift on its own, so the excavator or grab is sized against the biggest stone in the load rather than against the total this returns.
- Stone below the waterline weighs less than it did on the lorry. Buoyancy removes the weight of the water it displaces, which leaves ordinary limestone or granite at roughly 60% of its weight in air and a lighter sandstone at less again. This is the delivered weight, not the weight holding the stone down once it is under water.
- A volume measured off stone already in place is not clean stone. Years in a watercourse pack the voids with silt, sand and roots, and that infill comes away with the rip rap, so the weighbridge ticket on a removal runs above what the same yardage of new stone would weigh.

Rip rap is the large angular stone used for erosion protection on banks, outfalls and shorelines, and it is specified by stone size as much as by quantity. The density reflects large pieces with correspondingly large voids between them. Sizing matters more than volume: stone too small for the flow it faces is simply washed away, and the required size comes from the design velocity rather than from what looks substantial on site.
