About this detail

An eight-inch concrete masonry unit wall bears on a concrete foundation footing, with foundation dowels matching the size and spacing of vertical steel. Horizontal reinforcement is tied to the vertical steel on the same side and set within bond units, with the invert bond unit featuring broken-out cells for cleanouts as required. The concrete slab intersects the wall above a gravel subgrade, tied with number four reinforcing bars at twenty-four inches on center. The footing contains two number five top and bottom bars, unless noted otherwise, along with number three ties at thirty-two inches on center. Three inches of clearance is maintained around the footing reinforcement, and the top of the footing is wood-floated.
