How far below the sidewalks and driveway does my soil need to be before laying sod?
A.) The normal thickness of sod is 3/8″- 3/4″, all sprinklers can be set at ¾”above the dirt level. Dirt around sidewalks can be down as much as 2-4″ to allow for root build up and filtering of dirt out of the air. The dirt level will naturally get higher and higher as the years go by. This is because lawn is a natural air and water filter. It filters dust and dirt particles out of the air and water improving the environment.
