A perimeter-wall foundation is created by attaching galvanized-steel corrugated panels to an in-place structure. The freely hanging bottom edges of the panels, which have continuous deformation specific to the enhancement of bearing and anchorage within concrete, are cast in-situ with footing concrete, so becoming a cast-in-place perimeter-wall foundation, capable of residential-scale bearing and shear loadings. The panels can have screened ventilation built into the top, utilizing corrugation flute apertures, or they can be thermally optimized for cold climates.
