Limestone is a white / grey solid stone, that is crushed, therefore leaving corners and edges. Limestone is most commonly used for driveways and parking lots.
We carry #8, #57, #411 and #10 screenings. As a general rule, the smaller the stone, the smoother the finish will be.
In soft areas, you should start with a larger stone, and add on layers of smaller stones until the desired surface is achieved.
