Yes there are vertical rods every third row and horizontal in the blocks also. There will be not water from rain as this wall will be under roof. Would you think the wall would at least hold the weight of gravel until a structure is built on it?
We have a 12 foot high retaining wall (12" blocks). We installed drains around the concrete footers. To fill behind the wall will be approximately 4 feet wide and forty feet long and of course 12 block high. It will sit against a moist hill. Should the back fill be all gravel and if so does it...
