DIAVIK MINE – DIKE A418
DIAVIK MINE – DIKE A418

2005 - Northwest Territories, Canada

Diavik Diamond Mine is located in the North West Territories of Canada, approximately 1,300 miles south of the North Pole. The A-418 Dike was built as part of the planned mine expansion. The water tightness of the dike was affected by the installation of a cutoff composed of plastic concrete cutoff wall, jet grouting and pressure grouting. The Jet Grouting, performed by Trevi Foundations Canada, was installed to seal the base of the cutoff wall to the pressure grouted rock, making the dike watertight for the open pit excavation.
