About this detail

This structural detail shows a reinforced concrete retaining wall and continuous spread footing assembly designated as Type 2. The stem wall features vertical reinforcing bars designated as "A" and "B" bars, with a wall thickness labeled as "t" and a top clearance of one and one-half inches. The footing includes bottom longitudinal "G" bars, top "E" bars, transverse "F" bars, and four number five corner hairpins with three-inch typical concrete cover. All concrete contact surfaces at the cold joint between the stem and footing are specified to be roughened to a one-quarter-inch amplitude. A perforated or solid drain line is positioned behind the wall heel where required per architectural drawings, surrounded by drainage backfill. Finish grade elevations on both sides of the wall are established per civil drawings, with the top of wall located per the civil wall profile.
