Coast Defence Systems

Port protection works

Zeta performs backfilling works outside port defences, such as dams and quays attached to the ground, to protect internal port basins from sea motion, using two different types of construction:

  • Cast or with rocks: in natural rock or artificial blocks
  • Vertical wall: with cellular reinforced concrete caissons or overlapping blocks

Coastline protection works

Zeta undertakes coastline protection works to protect the coast against erosion due to the waves, typically in the form of a reef with rocks of various sizes, such as:

  • Channels
  • Emerging and segmented flow breaks
  • Underwater barriers


Zeta S.r.l. was UNI EN ISO 9001:2008 in 2005 for its quality management system.
