10.030.0633 Lintel rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) lintel, soffit, and accessory units around window openings. The existing TC is replaced with new extruded 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, and an integrated flashing system installed to protect existing structural steel. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. Accessible existing structural steel is also protected by cleaning and coating with a corrosion-inhibiting co
