The situation is that my wife and I have decided to put a small patio out back for grilling and such. The area is approx 12'x 9'. Our neighbors across the street are in the process of putting in a pool and have found that the previous owner had a thing for river rock and have been digging the stuff up for the last two weeks. I was thinking that the large flat rock would make for a nice patio and an inexpensive route (they offered it to me for free). I have never done anything like this before and I am assuming I am going to want to lay down some concrete and mount the stones within the field. The area lies at the base of a hill and although we have a rock wall dividing the hill from the area the ground still gets quite damp. I am wondering if : 1. This is a sound idea to begin with. 2. I stated concrete but is there something better for an anchoring agent. 3. How would I prepare the ground, including a base ie gravel. Also open to any tried and true replacements for the river rock.
Thanks in advance
