It will be a semi-circular wall, 24 inches high, encompassing a garden. the back wall is the block wall foundation (that has been dry-locked). The blocks are 8x12x6. Since the block has a lip, i hope to keep it dry. If i see shifting, i think i will likely try a 'liquid nail' mortar.
pea gravel provides the drainage.
