About this detail

This structural section details a cast-in-place concrete trench intersecting with concrete floor slabs on either side. The trench walls are reinforced vertically and horizontally with 20M reinforcing bars at 250 millimeters spacing each way top and bottom, complemented by a set of ties sized per the structural schedule. A cementitious crystalline waterstop system is specified at the base joint, combined with an exterior waterproofing membrane and rigid insulation applied to the wall exterior. The assembly rests on a 50 millimeter mud slab over a compacted subbase, with top reinforcing extending continuously into the adjacent floor slabs.
