Abstract: A method of constructing a shallow pier foundation building that includes a) placing a plurality of insulating pier forms along a perimeter of the building; b) placing a plurality of insulating concrete forms between the insulating piers to form a continuous insulating surface to the surrounding soil and a continuous forming surface to provide a slab form; c) placing a concrete composition in the insulating piers and insulating concrete forms and allowing the concrete composition to cure and harden; and d) placing a concrete slab composition in the slab form and allowing the concrete composition to cure and harden.

Abstract: A load-bearing platform that includes a base and a lity of legs extending from one side of the base, the load bearing platform is at least partly made expandable polymer matrix that includes an polymer of a polyolefin and in situ polymerized aromatic monomers.

Abstract: A load-bearing platform that includes an expandable polymer matrix core and a skin disposed over a bottom side of the core. The core includes a base and a plurality of legs extending from one side of the base, the legs having one or more core insert openings in a bottom surface of the legs. The skin includes a plurality of legs, each adapted to accept a leg of the core and one or more skin insert openings corresponding to a core insert opening, where at least one leg insert per leg is inserted into an insert opening. The load bearing platform can be used for shipping articles.
