Abstract: A foundation wall includes a frame having a front side and a back side. The frame further includes a plurality of vertical stud members having a first end and a second end, a top beam attached to the first end of the plurality of vertical stud members, and a bottom beam attached to the second end of the plurality of vertical stud members to define a plurality of cavities between adjoining vertical stud members. Rigid insulation is adapted for positioning in the plurality of cavities to become a load-bearing part of the frame. One or more structural sheets is affixed to the front side of the frame and to the back side of the frame. A waterproof bond is formed along an interface between edges of the one or more structural sheets and a periphery around the front side and the back side of the frame.

Abstract: An engineered wall system for use above or below ground constituted of zinc-borate treated timber strand studs with sheets of structural fiberglass reinforced plastic and rigid foam insulation. The invention is particularly suitable as an alternative to other materials and methods commonly used to construct foundations for residential structures. This wall system exhibits great strength, durability, as well as improved resistance to mold, insects, water and fire.
