Concrete structures—whether historic landmarks or everyday infrastructure—face inevitable challenges over their service life. This presentation will explore a range of structural strengthening methods and concrete repair techniques, with a focus on how engineers can select and implement the right solutions for both new construction and rehabilitation projects. Attendees will gain insight from real-world case studies, including the rehabilitation of Notre Dame Cathedral, preservation efforts at the Roman Colosseum, and practical applications for parking garages, bridges and powerplants.
In addition to repair and strengthening, the session will address the critical roles of waterproofing and soil stabilization for ground improvement and the prevention of structural failures.
