Claim:
A building foundation system, comprising: at least inner and outer elongated form panels each having an inwardly facing side surface which surfaces are arranged in an opposing spaced apart relationship to define an upright cavity having an outer and inner periphery; at least one form insert, said insert including a body section having a top edge and a bottom edge defining a longitudinal axis, first and second side edges extending perpendicularly between said top and bottom edges, a first side surface, and a second opposite side surface including at least one outwardly projecting recessed section, said at least one recessed section having an outer surface with a parallelogram shape and being in parallel with the longitudinal axis of the body section, and a plurality of side sections extending between the second side surface of said body section and said outer surface at an acute angle; said at least one form insert designed to be placed in said upright cavity with the first side surface abutting against the inwardly facing side surface of the inner elongated form panel, further defining a settable mass receiving area between the second side surface of the at least one form insert and the inwardly facing side surface of the outer elongated form panel in which a foundation wall having an outer surface defined by the inwardly facing side surface of the outer elongated form panel and an inner surface defined by the second side surface of the at least one form insert is formed, said settable mass receiving area including a plurality of horizontal and vertical channels either between adjacent recessed sections in the at least one form insert or around the periphery of said at least one recessed section of the at least one form insert; and a reinforcing material disposed in at least some of said horizontal and vertical channels.
