I have a 16' x 19' parking pad that has been excavated to 6" below grade. The soil is clay - pure red clay. I want to lay down gravel and pavers (may do cobblestone if I can get them cheap enough, otherwise it will be concrete pavers).
Do I need to excavate more to get enough gravel down? Small car is the only thing that will park on it.
Can I do anything else that would not require me to excavate more? I was thinking about using grout instead of sand. Adding plastic and landscape fabric. Any ideas?
