ABSTRACT OF THE DISCLOSURE Walls and other structural members are fabricated by mass production techniques by first coating two mold halves individually with a hardenable polyester while their surfaces are horizontal or slightly inclined, joining the molds together to form a hinge at one point and rotating them together on the hinge, elevating the temperature of the molds toward the temperature of a foaming reaction, and positioning the molds with their surfaces inclined while introducing a mixture in the mold cavity which foams to polyurethane in an exothermic reaction. Electrical conduits and other internal elements including water pipes are held in place by a layer of polyester which hardens before the molds are moved to the vertical. A product of excellent strength and other characteristics is produced economically.
