Slab on Grade Depression

Elements

About this detail

Concrete slab on grade depressions are detailed across three depth ranges with specific reinforcing configurations and slope transitions. For shallow drops of three inches or less, a natural slope connects the elevations with standard slab thickness and reinforcing. Medium depressions between three and twelve inches incorporate additional longitudinal number four bars at all bar bends with a one-foot minimum offset. Deep depressions from twelve to forty-two inches require number four bars at eight inches on center, corner bar details, and coordinate with architectural drawings for location, depth, extent, and edge conditions. Pipe sleeves are included where penetrations occur through the vertical drop.
