Asphalt core dam for the Nemiscau-1 dam, Quebeck, Canada.

Veidekke, through its Canadian subsidiary, Entreprises Veidekke Industri Québec and in co-operation with Pavex Ltee., built the asphalt core for the Nemiscau-1 dam. The small dam is part of the Eastmain-1 Hydroelectric Development which includes many dams or dikes. One of the smaller dikes, the Nemiscau-1 was redesigned from moraine/clay-core to central asphalt core, as Hydro Québec wanted to test out this method in practice before deciding on the design for new upcoming projects where clay or moraine is not readily available.

Veidekke Industri was during the preliminary stages participating as advisor for the project before being awarded the contract for construction.

Project description

The dam is 15m high with a crest length of approximately 310m and the core is constructed on top of a concrete plinth.

A small modern batch plant was established near the dam.
