About this detail

This concrete foundation detail shows a grade beam supporting a wall panel with a pour back strip at the slab-on-grade transition. The grade beam and its reinforcing are sized per plan, sitting twenty-four inches minimum below the top of footing with footing width and height per plan. #4 panel-to-footing dowels are spaced at thirty-six inches on center, typically with an additional dowel six inches from each end of the panel. The wall panel features continuous #5 reinforcing bars, with #4 bars at eighteen inches on center plus five #4 bars at six inches center-to-center at each end. The slab-on-grade is reinforced with #3 bars at sixteen inches on center each way extending twenty feet into the building from the slab edge. #4 bars at forty-eight inches on center align with hook dowels through the pour back strip, extending ten feet into the interior slab pour. The face of the wall panel below the finished floor elevation is intentionally roughened, and the exterior is backfilled with two-sack slurry unless otherwise approved by the geotechnical engineer.
