Refurbishment, Les Cedres Dam

Project description

Les Cedres Dam, Saint-Thimothee, was built in 1914. It needed to be solidified.

Initially, this $ 2.15 million project consisted in repairing the downstream pillars by replacing the damaged concrete. At this difficult-to-access location, we opted for the installation of tubular scaffolding across the entire structure, to be able to work on the entire site.

Subsequently, the work to be done upstream consisted of installing a concrete plug on 3 hydraulic passages. These works were planned for diving. Instead, we planned to build a waterproof formwork, which allowed us to work dry.

Finally, we experimented with the use of self-consolidating concrete, generally used for repairing walls. The pressure at the formwork being strong, we had to adapt our construction methods accordingly.

This work, which began in mid-June 2010, ended on December 17, 2010. We met the client’s schedule.
