I start with about 4" to 6" of 3/4" minus as a base then start building with split grey basalt. Since it's conforming to the outside of the 11' diameter round patio, I can use squares and rectangular pieces rather than hunt and pick for concave shapes.
|The first 4 layers. As it's built, I fill the back with 3/4"-minus rock and let it migrate between and below the stone. This helps support and steady the unlevel surfaces.
|Moving along slowly. I try and vary the rock height to give it character but that creates lots of challenges.
|At this point I stopped building the wall and would complete later. This part of the project was moving too slowly and I was anxious to get to the patio part.
|The completed rock wall bench seat. The top pieces are the same material as the round porch and pathways and are mortared in, giving it a solid feel.
