Transit Tunnel Waterproofing

Finch West Light Rail Transit

Client: Metrolinx/Infrastructure Ontario

Where: Toronto, ON M3J 2W1

What We Did: “Bathtub System” installation in below grade light rail transit tunnels and pedestrian walkways. This was achieved by fully wrapping the area to be waterproofed with sheet membrane waterproofing system to provide waterproofing on both horizontal and vertical planes.

Challenges: Working below grade poses challenges as we must deal with very high hydrostatic pressure. We are able to overcome this with our professional installation and high attention to detail. Additionally, on large project like these multi-faceted trade relationships are an important component in dealing with expedited timelines.
