Prepare the Area
Use landscape marking paint to outline the area for the new patio (Image 1), and remove unwanted plants that lie directly in the outlined area. Check the elevation of the patio area with a laser transit to make sure that it allows for drainage (Image 2). Dig out the area to allow for the gravel base, a course of sand and the tile pavers (Image 3).
