Dry-stack Stone Wall
I love dry-stack stone walls. They’re rustic, beautiful, traditional and functional. The most important thing is to angle the wall back into the bank. With every level you build, simply place the stone about 1 to 2 inches back from the edge below. When you’re done, the wall will angle backwards into the bank. Use longer, narrower rocks as deadmen to strengthen the wall.
Place the narrow face of the rock out and the long section back into the bank. Additionally, stagger the joints in the wall so they don’t align directly on top of each other. These three things will strengthen the wall.
The key to a beautiful dry-stack wall is keeping the joints symmetrical and small. Use the natural shape of the rock to determine which hole to put it in. However, almost every rock will be imperfect and need trimming. I use a masonry chisel and a Skilsaw with a diamond blade to manipulate the stone. Don’t make any cuts that will be visible on the finished wall. Be careful, but you’ll have to use the Skilsaw creatively to cut and grind off parts of the rocks to shape them for the wall.
