About this detail

An exterior concrete grade beam measuring three feet wide by one foot six inches deep supports an adjoining concrete slab and exterior cladding. The grade beam is reinforced with five number five top and bottom bars extending two feet six inches minimum into the concrete pedestal, enclosed by number five ties at twelve inches on center with typical three-inch concrete clear cover. A continuous keyway with a waterstop is cast into the top of the grade beam at the cold joint. Slab dowels matching the size, grade, and spacing of the slab reinforcement extend from the grade beam into the concrete slab. Exterior insulation is installed along the outer face of the grade beam per architectural drawings, maintaining a two-inch clear dimension at the top.
