These protective dykes and harbour jetties are used to protect a port or part of a port from the actions of the swell. Essential to the proper operation of ports, these artificial structures are subject to degradation and require regular maintenance to guarantee their life for more than a hundred years. The Negri company has a great know-how in this type of work. We have been actively involved in the maintenance and improvement of the seawall off the port of Marseille for more than 40 years.
