How to estimate crushed stone

- #57 stone drains well and is common for French drains and under slabs.
- Crushed stone weighs roughly 1.4-1.5 tons per cubic yard.
Frequently asked questions
What is the difference between gravel and crushed stone?
Crushed stone is mechanically broken so it has angular, locking faces; gravel is naturally rounded. Crushed stone compacts harder, which is why it is preferred for bases.
