As part of the expansion of the largest open-pit gold mine in Canada, the Canadian Malartic Mine will build a dyke over a length of 1km100 and reach a height of more than 20m compared to the current level of the natural ground to contain mining residues. Menard Canada was mandated by Norascon to install Vertical Drains through the soft clay on two sectors of the dike. The improved right-of-way totalled 375m in length by 45m in width.
