Our 57 rock gravel is typically used in areas that need drainage support. It is one of the most common gravels for driveways, RV Pads, French Drains, Walkways, Back-Filling Walls, and much more! The unique shape and durability of this stone also makes it ideal for use in road construction. It’s white-beige color adds a clean and modern look to any outdoor project. These rocks are about 3/4 inch in size.
