Université de Montréal - Restoration of the Ernest Cormier Amphitheatre Ceiling

Built between 1928 and 1943, the Université de Montréal's Roger-Gaudry pavilion is a gem of Art Deco architecture. The Ernest-Cormier amphitheatre reflects the refinement of this renowned Canadian architect, notably through the elegant composition of its decorative plaster ceiling.

In December 2024, our team carried out a thorough assessment of the ceiling: detailed visual inspections, comprehensive photographic documentation, and pull-off tests conducted with structural engineers. Three types of deterioration were identified — hairline cracks, major cracks, and areas of plaster delamination — allowing interventions to be prioritized by urgency.

Restoration work focused on consolidating detached plaster, repairing cracks, and applying a specialized primer, carried out across two distinct zones with careful attention to matching the original finishes. Testing confirmed the excellent adhesion of the repairs.
This project reflects the University's commitment to preserving its architectural heritage, while ensuring the continued safe use of this landmark space.
