Sub-Base. Sub-base is the term we use to describe the area that lies directly underneath the artificial grass. It is most commonly made up of a sand/gravel mixture, although in some instances it consists of concrete, asphalt or even a wood base. common question is âWhy do I need to install a sub-base? Why canât I just install my artificial grass on top of dirt?â The answer is that native soil is expansive (particularly soil with clay in it) and when it gets wet, the soil expands; when it dries, the soil contracts.
