Crushed Stone 7 Stone

#7 stone is crushed rock screened between about 1/4 inch and 1/2 inch. The pieces come out angular from the crusher, so they lock together under weight instead of rolling around. Most of the fine dust gets washed out, which is why it drains so fast when water hits it.

The 7 is a screen size from the ASTM D448 spec (also called AASHTO M43). It tells you how big the pieces are and says nothing about what kind of rock they came from — you'll see #7 made from limestone, granite, or trap rock depending on your local quarry. A yard weighs roughly 2,700 pounds, so figure about 1.35 tons per cubic yard when you're pricing out a load.

How to choose within crushed stone 7 stone

Compaction over drainage

Angular pieces lock together. Pick a smaller size when you need the surface to stay put under a driveway or path.

Drainage over compaction

The larger the piece, the more room for water to move through. #1 or #57 for a French drain; #8 or smaller reads as loose gravel.

Washed vs. unwashed

Washed has the dust rinsed out, so it drains faster and won't track into the house. Unwashed compacts harder — better under a paver base.
