Large-scale hydroelectric projects

From 1987 to 1996, Les Excavations Marchand & fils builds infrastructure to serve the five hydroelectric power plants installed at James Bay, its first major foray into the far north of Quebec.

We quickly carved out an enviable place in the highly competitive energy megaprojects sector. How? Well the secret to pulling off this feat was the diversification of our operations and the support from a highly qualified team that excelled at innovating and adapting.

Major hydroelectric clients rely on us for highly specialized work including:

  • Power plant excavation
  • Canal excavation
  • Diversion canal excavation
  • Dike construction
  • Dam construction
  • Coffer dam construction
  • Construction of dikes with cement-bentonite walls

  • Release channel construction
  • Grouting and consolidation
