I want to install a gravel patio. Is it better to use limestone as base or sand, or do I need to layer the two prior to putting the gravel down that I'm going to use? Patio area will be 16' x 20' and am planning on a firepit in the middle of it.
Also any recommendations on gravel size? I'm currently looking at using 3/4" instead of pea gravel.
Thanks for any help.
