Université de Montréal - Restoration of the Ernest Cormier Amphitheatre Ceiling

Built between 1928 and 1943 at the Université de Montréal, the Roger-Gaudry Pavilion is a significant Art Deco structure. The Ernest-Cormier Auditorium exemplifies the refined design approach of renowned canadian architect Ernest Cormier, evident in its elegant ceiling composition and careful attention to spatial harmony.

Our team conducted a comprehensive assessment of the auditorium's decorative plaster ceiling in December 2024. This included detailed visual inspections from multiple vantage points, photographic documentation, and collaboration with structural engineers for pull-out testing. The investigation revealed three distinct types of deterioration: microfissures, significant cracks, and areas of plaster delamination. Our methodical approach allowed us to map these conditions and prioritize interventions based on urgency and potential risk.

The restoration work focused on stabilizing and repairing the most critical areas of the ceiling. Our intervention strategy included the consolidation of loose plaster, crack repairs, and the application of a specialized primer to reinforce microfissures. The work was carried out in two distinct zones, with careful attention paid to matching the original finishes. Testing confirmed the excellent adhesion of our repairs, demonstrating the effectiveness of our restoration methodology.

These interventions represent more than just technical repairs - they embody the University's ongoing dedication to preserving its architectural heritage while maintaining world-class facilities for its academic community. Our carefully planned phased approach ensures the auditorium's continued safe use while establishing a framework for future maintenance and preservation of this significant space. This project exemplifies how thoughtful conservation can protect both the material and cultural value of our institutional landmarks.
