About this detail

A storefront sill bears on a concrete foundation wall with an aluminum sill cover flush with the top of the sill, secured via fasteners and sealant. Fluid-applied polyurethane waterproofing is applied to the exterior face of the footing over a continuous cant strip, with an underslab vapor retarder sealed at the corner of the footing. A concrete exterior walk slopes away from the building, separated from the foundation by joint filler strips, continuous sealant, and a backer rod. A backer rod and seal with weeps at sixteen inches on center are provided at the storefront threshold.
