I have never done this before, but I am very interested in doing this for a living with my lawn care. No one in this area does this work. I built a 12/24 patio with a tiki hut on it. It was made with stones. I used treated 2x4's leveled around, packed it with crush and run gravel and packed it with a vibrator and then laid my rocks. After done laying rock, I swept play sand in between to keep rocks from rocking around. So far so good. Is there something else I should have done different? I also put edging around the rocks to keep them together and keep sand in. Thanks for any input.
