Crushed Stone
We deliver every grade56 Stone
#56 stone is crushed rock screened between about 1 inch and 3/8 inch. The pieces are angular, so they lock together under weight instead of rolling around. It drains water well and still packs tight enough to hold a load.
The 56 is a size number from the ASTM D448 spec. It's the range you get when a #5 screen and a #6 screen are combined, and it says nothing about the rock type, so you'll see it quarried as limestone, granite, or trap rock. Price runs close to other 1-inch base stones and moves with how far the load has to travel.
What people use it for
How to choose within 56 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.
