An aluminum curtain wall sill mullion bears upon a concrete floor slab adjacent to a stainless steel diffuser grate and drainage trench. A foil-faced self-adhered membrane runs beneath the sill assembly while a stainless steel flashing coordinates with silicone sealant and backer rod at the glass interface. Below-grade self-adhered waterproofing membrane and a drainage panel extend down the exterior face of the slab.
