This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) cornice, balustrade parapet, and accessory units. The existing TC is replaced with new hand pressed TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, an integrated flashing system installed in the cornice, and stainless-steel through-wall flashing under the coping. The flashing system in the cornice includes a self-adhering flashing secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints.
