Kannaviou Dam is a rockfill structure with a concrete face (CFRD) and is of great importance to the Cyprus water management programme. It is the first Concrete Face Rockfill Dam built in Cyprus, so it is of great technical interest and is the second highest with 75m height.

This paper presents the methods used in constructing the dam, the quality control applied to the various materials forming the embankment zones and the concrete face construction. A specific reference is made to the unique method used for the first time in the testing of the copper waterstop brazing with the use of a vaccum box developed on site for the purpose. A comprehensive instrumentation system was installed for monitoring both the dam's embankment and the face slab perimetric and vertical joints. Some results of the monitoring of the behaviour of the dam during construction are also presented.
