Construction Of Konsko Dam


The dam will be rock filled, with a central vertical asphalt-concrete diaphragm as a watertight element, which is 60 cm wide, and extended to 120 cm in the lowest 80 cm of the height above the connection to the grouting gallery.

Supporting bodies shall be constructed of rock fill – gabbro, having two transition zones toward the diaphragm (upstream and downstream), made of rough crashed stone. The dam will be 79.65 m high, and in its body, the upstream cofferdam, used for protection of the construction pit, will be built-in

The Project Scope covers

  • Asphaltic concrete core
