The detail illustrates a cast-in-place reinforced concrete trench positioned along the centerline between concrete slabs. It features continuous steel reinforcing bars, ties, a mud slab at the base, exterior waterproofing membranes, and rigid insulation along the vertical trench walls. A cementitious crystalline waterstop system is specified for waterproofing at the base, and top reinforcing extends into the adjacent floor slabs.
