Crushed stone: The sub-base layer uses 3- to 5-inch diameter stones. The 1- to 1.5-inch top gravel creates a smooth driving surface. Edge restraints: Borders like plastic curbing, treated wood, or metal landscape edges keep gravel contained. Geotextile drainage fabric: Optional over the sub-base for extra weed and moisture protection.
