Extension of the seal wall in the Port of Barcelona, in a section 1,150 m long.

This outstanding type of infrastructure is arranged in a mound and formed by a quarry run core, different armor with breakwaters and blocks of different weights (up to 40 T) depending on the different sections of the new dike after its extension.

In enclosure 4, seal walls have also been built along 700 m, by means of a mound section formed by a graded aggregate core and breakwater armor.
