(4)When the thickness of such wall is taken from the requirements of this Chapter for empirically constructed walls, such thickness shall be that applicable to the building-units and mortar comprising the backing or to those compromising the backing or those comparing the facing, whichever building-units and mortar require the greater thickness.

(5) The use of facings in faced walls shall otherwise comply with the requirements of S.A.B.S 073.
