Stone Repair and Restoration

Landmarks Illinois & IMI Annual Historic Preservation Education Event

Stone has been used for thousands of years for many building types and comes in myriad shapes, sizes, and properties. Extremely durable when maintained, over time, stone can deteriorate when exposed to weather, moisture, or improper previous repairs or pointing mortar. Learn about the formation of stone, material properties of common building stone, and deterioration mechanisms. You’ll discover best practices for stone treatment options like dutchman repairs, cementitious mortar repairs, stone finishing, and stone carving. Walk through a case study of the Tribune Tower to hear about the limestone façade rehabilitation process, including assessment prior to construction, development of restoration details, the unique cathodic protection system installed at the flying buttresses, and execution of the work by the masonry restoration contractor. We’ll cover lessons learned and challenges experienced in rehabilitating the tower’s facade. Finally, gain a deeper understanding of stone repair concepts through fascinating demonstrations of stone composite mortar repairs, dutchman repairs, and carving techniques.
