Pros and Cons of a Stone Driveway
Installation Process . A new stone driveway requires that the sod and topsoil be removed, and the surface needs to be graded. Depending on how much stone and gravel you plan to add, you will need to dig at least 6 inches deep, and preferably 10 to 12 inches. Compact the soil, then add a 4- to 8-inch gravel base, topped with 2 to 4 inches of stone.
