How deep does my sub base have to be for 15x32 Super natural 80 job?

Regardless the type and size of your artificial grass, the installation of turf to replace real grass lawns are the same. When it comes to the sub base preparation, we typically recommend to excavate 4” of soil, and build the turf sub base of 2-1/2” with drain rock at the bottom and 1-1/2” decomposed granite on top: both layers need to be wetted and compacted at 90%.
