Abstract: A lightweight stone-work column apparatus (20) including a side wall assembly (20) formed from a plurality of stone-work pieces (32) in side-by-side relation. A mortar material (31) is adhesively mounted to the collective backsides and joints (20) of and between the stone-work pieces (32). This mortar material (31) is supplied in a relatively thin radial depth dimension, relative the longitudinal axis (30), while being sufficient thick to support and bond together the plurality of stone-work pieces (32) together as a unit. A tube member (45) is positioned in a cavity (46), formed by the stone-work pieces (32) and the mortar material (31), in an orientation extending from the first opening (47) to the second opening (48). A polymer backing (20) positioned in a gap between an outer surface of the tube (45) and the backside of the mortar material (31) for strengthening of the collective stone-work pieces (32).
