03.020.0219 Wall system Stone wall, coursed ashlar veneer w/ brick backing

Last crawled date: 2 years, 3 months ago

This wall system illustrates a 4” ashlar veneer with brick backing. The coursed ashlar veneer is tied to a 12” brick backing with metal “Z” veneer anchors and at the top course by a metal cramp. The anchors engage with the veneer stone by penetrating a kerf or channel that is cut into the top surface of each panel. The mass of masonry deflects bulk water penetration but is understood to take on a percentage of moisture that is free to evaporate slowly from the mortar joints on either side of the wall over time. The wall is topped with a splayed copestone that prevents water penetration and has drips at either underside edge to direct water away from running down the façade.
