Custone and bridge N Treksilä, Overbridge N Munkby

Overbridge N Munkby, Centre for Economic Development, Transport and the Environment in Uusimaa (ELY Centre)

The repairing of the edge beams of these two bridges was realized by a shell molding technique. The old concrete surface of the edge beams was removed (appr. 40 mm) and was replaced by self-sealing concrete C35/45-3 fortified by the Custone copper alloy.
Thus, a new strong surface is achieved by the method developped by Custone which bind chlorides penetrating into concrete. The work was executed by Destia Ltd.
