I am planning on making a gravel patio with firepit on the side. I was planning on clearing the grass of a 18X18 area and fill with a base material (Crushed stone and dust), compact it then add 2-3 inches of a decorative stone(larger than pea gravel). My question concerns the depth of the base and the depth of the top stone layer. How deep for each. the area has sufficient drainage. any suggestions would be helpfull.
Thanks everyone in advance.
