    Is a bond beam required in a fully grouted masonry wall?

    Thank you for your replys. hokie66, Yes I am from Australia. While the wall does have horizontal reinforcement, it did not specify which block to use. I agree that a bond beam is required and the use of "H" or "knockout" blocks with horizontal reinforcement will meet this requirement. Do you...
