This structural detail shows a reinforced concrete foundation footing beneath a garage door threshold, featuring top and bottom reinforcing bars sized per plan with three inches of clear cover. Dowels match the size and spacing of the slab on grade reinforcement unless poured monolithically with an optional cold joint. A deformable material and sealant fill the joint between the foundation stem and the exterior driveway slab, which rests on subgrade. The footing is embedded below the lowest adjacent grade at a width specified on the structural plans.
