University of Guelph Tunnel & Stairway Repairs

CSL completed the first phase of this project in the Summer of 2021.  We returned for phase two in the Summer of 2022 which required hazardous materials abatement and extensive civil work. The tunnels required restoration work, and waterproofing including surface preparation, shoring design, top surface delamination repairs, concrete wall repairs, and replacement of reinforcing steel. The project also required concrete curb, and sidewalk restoration along with the installation of concrete stairs, landing, retaining walls, and concrete ramp. As well as some minor reworking of the mechanical piping and electrical within the tunnels.
