About this detail

Masonry control joint configurations occur at floor, roof, joist, and deck bearing locations alongside horizontal bond beams and joint reinforcing. A continuous vertical control joint features a backer rod and caulk joint on each side, with two vertical reinforcing bars placed on each side of the joint to match the vertical wall reinforcing. Horizontal reinforcing is either interrupted at the control joint or run continuously through, depending on the specific condition. Dur-O-Wall wide flange joint reinforcing is used, with sizing varying based on the wall thickness. For single layer vertical reinforcing, horizontal bars terminate with standard 180-degree hooks at the vertical reinforcing, with the web of the block above cut to maintain three-quarters of an inch coverage.
