ABSTRACT:
A load-bearing wall panel is fabricated by disposing an assembly of spaced-apart and aligned, hollow-cored bricks onto a molding base containing melted paraffin. Contact of the cooler bricks with the melted paraffin forms a thin skin of solidified paraffin on the brick bottom portions and forces melted paraffin within the joints forming therein a double-convex configuration of solidified paraffin, thereby water-proof sealing the brick bottom portions and joints preparatory to mortar introduction. After curing of the mortar introduced in the joints and cores, the resulting wall panel has load-bearing capacity and unique, double-concave mortar joints that are smooth, water-proof and weather-proof.
