Abstract
Abstract An expanded foam core such as a polystyrene foam board is covered on only its sides and top with a fiberglass reinforced cementitious material to form a solid base. Heavy steel coils can be embedded in the composite for receiving steel posts which serve to mount air conditioners or the like. Alternatively, a recess can be formed in the composition for use as a transformer pad.
