This detail shows 3 cm (1 1/4 in.) thick dimension stone anchored to an interior wall substrate with Z-strap anchors at the top and bottom of each stone panel; an L-strap anchor (not shown) may be used at the bottom course. The anchors are sized and spaced per structural design and are fastened to the wall framing through an anchoring plate behind the wallboard. To correct for variations in the substrate, the anchors are shimmed as necessary to result in finish that is plumb. A continuous rebated kerf is cut in the stone to receive the anchors and to achieve a tight joint between the stone panels. Each panel bears on a plastic or stiff rubber bearing shim supported by the anchor, keeping the panels level. Joints between the panels may be finished with compatible sealant and backer rod (not shown for clarity).
