Gravel
We deliver every gradeGravel 9 Stone
#9 stone is crushed rock screened between about 3/8 inch and 1/16 inch. The pieces are small and angular, with a little stone dust mixed in. That mix locks together tightly when it's stepped on or driven over, which is why you'll see #9 packed into the joints of permeable pavers to hold them in place.
The 9 is a screen size from the ASTM D448 spec. It tells you how big the pieces are and says nothing about what kind of rock they came from. You'll find #9 sold as limestone, granite, or trap rock, and the price mostly tracks whatever's quarried closest to you.
