One cubic yard of crushed concrete weighs about 1.56 US tons and covers about 162 square feet at 2 in.
How to work out how much crushed concrete you need
- Measure the area in feet and multiply length by width.
- Pick a depth in inches and multiply it by the area to get a volume.
- Multiply the volume by the bulk density, 1850 kg per cubic metre for crushed concrete, to get a weight.
- Divide the weight by your supplier's ton or cubic yard to get what to order, and round up. Suppliers do not sell part bags.
- Add 10 percent. Covers settlement, uneven ground and the material lost around the edges. A second delivery for half a yard costs more than the extra you did not use.
How many tons in a cubic yard of crushed concrete?
About 1.56 US tons, at 1850 kg per cubic metre. Because published densities run from 1600 to 2100, the honest answer is a range: between 1.35 and 1.77 tons per cubic yard depending on grading and how wet the load is.

Crushed concrete and hardcore
In the UK trade the same material is sold as hardcore, ordered in tonnes and bulk bags, so the hardcore calculator works in those units and at those depths.
