A multi-track sliding glass door system bears directly on a concrete slab edge and footing with a flush zero threshold transition. A drainage line runs straight down through the footing and turns outward to the exterior at the mid-depth of the footing, positioned clear of all reinforcing steel. Self-adhered flashing or membrane is detailed at the slab edge junction below the track assembly.
