The Armoury


The Armoury is the only military building in Canada that is recognized as a national historic site. Located in the heart of Old Quebec, the building was inaugurated in 1888 before being destroyed by fire in April 2008 and later rebuilt between 2012 and 2015. This mandate involved the reconstruction of the building’s massive limestone and clay brick walls. Works included dormer and turret reconstruction, for which Rainville supplied worked and sculpted stone; buttresses were also reconstructed using pre-stressed rock anchors. Following the reconstruction of the main building and its annexes, a rear addition was introduced along with an adjacent building to the west, both of which were clad in limestone.

St-Sauveur Church Bell Tower (CHUM)


Saint-Sauveur Church (1865) occupied the corner of Viger and Saint-Denis streets in Montreal. In order to make room for the new CHUM, Rainville had the mandate to dismantle, number, and store each individual stone that made up the church bell tower, which was to be reconstructed a few years later. This challenge was met by our team of experienced masons. They were able to reassemble the bell tower to resemble the original, and made a few improvements to its new concrete structure—all in compliance with new paraseismic norms. As a first step, a stone-by-stone survey was carried out to determine the condition of each. Some stones had to be replaced or repaired to ensure the integrity of the newly-rebuilt tower.

Château Frontenac


A famous Quebec City landmark, the Château Frontenac was built in 1893, and has been renovated many times since. Rainville has carried out three masonry repair projects at the Château since 2007. Interventions mainly involved limestone and clay brick masonry repair as well as consolidation of the steel structure and replacement of window shutters. The greatest challenges encountered at this site were undoubtedly scaffold placement, working on an occupied building, and faithfully reproducing replacements for existing stone to respect the site’s heritage character.
