This concrete detail shows the intersection between a concrete wall and a concrete slab-on-grade, featuring multiple conditions including an adjacent slab, a recessed wall, and a wall recessed at a door. The concrete slab-on-grade connects to the vertical concrete wall with number four slab dowels spaced at twenty-four inches on center, supplemented by number four continuous horizontal rebar. The construction joint is coordinated with the architectural layout, and the contact surface is roughened to a quarter-inch amplitude. The slab thickness is specified as dimension t or a minimum of two times t or ten inches.
