In this example, synthetic turf was placed over a 4 inch crushed limestone base and nailed in the material. While this is not as permanent as a typical synthetic field application, the process typically lasts for at least one season. From time to time, the base material requires re-grading and the turf re-installed. Another option would be turf over concrete. ALWAYS make sure the turf is flush with the surrounding grass areas.
