Historic Terracotta Restoration

This program provides an introduction to terracotta as an architectural cladding material, its manufacturing, overview of its performance, and methods of repair. Terracotta as an architectural material in the United States had a very short run as a predominant cladding material; lasting from the late nineteen century until the 1950’s. During that time period though it was manufactured and used in excess as a durable and decorative material. Terracotta by itself is a high performance material, however when failure does occur it is generally associated with the secondary material used i n the assembly. This session will focus on understanding the methods of deterioration and repair strategies as well as how architectural terracotta is still used in more contemporary applications.
