Screenings Dust
We deliver every gradeDust
Stone dust is the fine leftover from crushing rock. It runs from about 1/4 inch down to a powder, with a heavy dose of very fine particles at the bottom. Pack it down and add a little water and it locks up tight and holds its shape, which is why you'll see it used as a setting bed under pavers, flagstone, and stepping stones.
You'll hear the same stuff called screenings, crusher dust, quarry dust, or manufactured sand fines. What you get depends on the parent rock at the quarry, so limestone dust is pale gray, granite dust is speckled tan, and traprock dust runs darker. It's usually the cheapest thing a quarry sells because it's a byproduct of making the cleaner sized grades, and most yards price it by the ton somewhere between $10 and $30.

What people use it for
How to choose within dust
Under pavers
Screenings compact hard and level flat — ideal for a paver setting bed. Uniform depth (about an inch) matters as much as the material.
Behind a wall
Fines pack tight against a retaining wall's back face. Add a drain line under the fines so water doesn't sit against the wall.
Not for drainage
These pack too tight to drain. Skip them anywhere you need water to move — French drains, downspout runouts, foundation perimeter.
