Step 2: Lay down a layer of geotextile fabric (sometimes called filter fabric or landscape cloth), followed by three to four inches of 1.5 to 1.75-inch crushed stone, topped by another layer of geotextile fabric. Step 3: Cover the geotextile fabric, making sure the edges are securely buried, with a minimum of six inches of the footing material of your choice.
