Manitoba will be hosting this webinar, entitled, Keeyask Generating Station – Embankment Dams – Bedrock Foundation Preparation and Grouting. This presentation will be in English.
Webinars are free for members and non-members – all you have to do is register!
Abstract
Keeyask is a 695 MW hydroelectric generating station located on the Nelson River in northern Manitoba approximately 730 km north of Winnipeg. Approximately 2.4 km of earthfill embankment dams were constructed for the project. These dams are founded on a highly variable bedrock surface, that ranges from competent bedrock to highly fractured and fault-affected bedrock, which required extensive dental concrete and foundation grouting prior to placing earthfill materials. This webinar summarizes the construction methods and treatments used to address the various bedrock foundation conditions, and discusses overburden excavation, bedrock excavation, foundation cleaning, dental concrete, and grout curtain construction. Methods for bedrock foundation preparation and treatment under winter conditions are also discussed.
