Port of Poti, Georgia

Port of Poti has a long history as the gateway of the Caucasus and Central Asia. It has been an important link in the legendary Silk Route, which will be restored in the coming years.

The main breakwater of Port of Poti dates back to 1873. Today it has a length of 1800 m and is covered by concrete cubes. A major part of the main breakwater has been rehabilitated with 2 m3 Xblocs. The existing concrete cube armour layer has been covered by an inverted granular filter structure on top of which the Xbloc armour and filter layers has been placed. The wide crest of the breakwater has been covered with Xbase units.
