Abstract: A corrosion resistant machine foundation formed from precast corrosion resistant vertical panels of an aggregate filled thermosetting resin defining an enclosed hollow form, each of the two side edge portions of each vertical panel intersecting one of the two side edge portions of an adjacent vertical panel at a predetermined angle and forming therewith a corner of the enclosed hollow form; the hollow form defining at each of the corners a barrier extending across and spaced from the corner from one vertical panel to an adjacent vertical panel and from the bottom of the hollow form to a predetermined height less than the height of the two adjacent vertical panels to form a vertically extending chamber; a portion of the bottom of the vertically extending chambers and the hollow form being filled with a cementitious material within the area of the hollow form between all of the vertical panels and each of the barriers to the top of each barrier, and each of the vertically extending chambers and the remaining ar
