Architectural Terra Cotta began as features within (brick) masonry facade assemblies and evolved into full building clad systems. This event will give an overview of general terra cotta facade construction and how the wall system functions. Characteristics of the material will be discussed along with its pathological tendencies. The material properties and its construction are contributors to both its success and beauty as well as its vulnerability to damage. Understanding the material and its vulnerabilities will help in developing appropriate repair and restoration solutions. Also discussed will be an overview of appropriate solutions for in-situ repairs, supplemental anchorage, replacement units, improved water management, and treatment of corroded steel. A case study on the preservation of the Old Cook County Hospital exterior masonry façade repairs will be discussed along with a virtual tour of terra cotta repair demonstrations.
