Reinforcing bar configurations for single and double mat concrete walls occur at corners and wall intersections. Vertical reinforcement utilizes four number five bars typically unless noted otherwise for double mats, and two number five bars for single mats, with alternate bends applied typically. Horizontal reinforcement is tied together using lap splices at intersections and corners. A specific corner bar may be used in lieu of a standard 90-degree hook typical at outside corners.
