Crushed stone is also known as gravel, pea gravel, decorative rock, or deco gravel. Super for surrounding trees and plants, crushed stone is also great for drainage areas, or as the base for driveways, side yards, and pathways. Ranging in size from 3/8" to 12+" in diameter, crushed stone has angular surfaces which help it lock into place. Low-cost and easy installation make it a fantastic choice to cover your largest areas.
