Jean-Talon (waterproofing membrane)

Between now and the end of 2019, an initial part of Jean-Talon station’s waterproofing membrane will be completely refurbished. We continue exterior work, blocking De Saint-Vallier Street. Automobile traffic is allowed to local residents only, between Bélanger and Jean-Talon streets.

As part of this project, we will also reinforce a foundation wall that runs above the Orange line.

Work on De Saint-Vallier street

We started replacing the membrane under De Saint-Vallier Street at the corner of Jean-Talon. The work requires to close De Saint-Vallier Street between Jean-Talon and Bélanger streets until December 2019. Automobile traffic on De Saint-Vallier is allowed to local resident only in both directions to facilitate access to their residence. The collection of garbage and recyclables will be done as usual.

Jean-Talon Street reopened to traffic

We recently completed the first phase of this important project.

  • Jean-Talon Street is now reopened to traffic in both directions.
  • We are carrying out work at the corner of De Saint-Vallier and Jean-Talon including the sidewalk.
  • A temporary and safe pedestrian path has been installed on one of the traffic lanes to allow pedestrians to walk east-west on the south side of Jean-Talon Street.

The construction site is progressing rapidly

Take a look at some pictures of the site. The excavation is in full swing!

Questions and Answers

Replacing a waterproofing membrane requires excavating the ground above it. We will dig one to seven metres deep, depending on the locations. The station’s pedestrian tunnels occupy the entire width of these streets underground. That is why it is necessary to completely close Jean-Talon and De Saint-Vallier Streets to carry out the work. Minimizing the number of work phases enables us to reduce the total duration and cost of the work and increase its efficiency.

It is a device that protects the station from water infiltrations. The membrane covers the station’s underground roof and is therefore located underground. Jean-Talon station’s waterproofing membrane dates back to the station’s initial construction in 1966, and the membrane has reached the end of its useful life.

There have been minor obstructions inside the station, since last January. The fencing, located at the head of the Côte-Vertu platform and at the end of the Montmorency platform, allows us to proceed with the reinforcement of the foundation wall.

Bus stops 92 - Jean-Talon West and 93- Jean-Talon will maintain at their temporary location until work is completed on the southern part of Jean-Talon street.

Note that the lines 30 - Saint-Denis / Saint-Hubert and 31 - Saint-Denis are already in detour, because of construction site of the Ville de Montréal.

Yes, it was a top priority for us to ensure careful coordination with other work providers in the area during project planning. Some phases will therefore be coordinated with other nearby projects to minimize obstructions and their duration.

In addition, the traffic plan was developed with the people in charge of the other sites and the boroughs to minimize the impact on area residents. However, under current conditions, public transit is definitely the best option.

Since we have to excavate the ground under these trees to access the underground roof of the station, we will unfortunately have to cut them down. All trees will be replanted in accordance with the City's development plan.

It is scheduled for the coming years.
