Istanbul, Turkey

In Istanbul, a new airport was constructed, which is the largest airport in the world. The airport is constructed by a consortium called IGA, which is formed by Cengiz, MAPA, Limak, Kolin and Kalyon.

On the north side of the airport a harbor was constructed which accommodates vessels with materials for the airport. This harbor consists of 2 breakwaters which will be armoured against the severe Black Sea wave climate by Xblocs.

Xblocs with sizes up to 16m3 are required for these breakwaters. Model tests have been executed in Ankara to verify the design.

Production of 3, 6, 9 and 12m3 Xblocs went well.  Block placement started in April 2017 and ended in 2018.
