We are trying to build a 9' cmu wall to support a concrete deck that will be 10' deep and 56 feet wide. There is already a solid footer in place. I have heard that surface bonded block walls are strong, relatively easy to build, and lend themselves to sporadic work times. If anyone can give us any tips, comments, or suggestions on how this works, we would greatly appreciate it. We also need the names of suppliers or companies to either use or avoid. We are located in eastern PA. Thank you for any help you can give us.
