The categories of marine and river civil engineering and public works are:
  • work in water (erecting cofferdams, constructing bridge piles), dredging; underwater works (by divers or other means);
  • clearing ditches, stream bank developments and reed and weed cutting.

These works require special techniques and materials. Work at sea involves construction, maintenance and repair.
Despite the statistical disruption of 2008, key figures point out a drop in exports in 2009 and 2010 as compared to 2007. The location of works by main geographical zones, as estimated on the basis of the industry association's inquiry on its members, shows a collapse in the amounts of markets in the EU in 2010, in terms of amount of orders (EUR 10 million against more than 200 million in 2009), which was not offset by the sizeable level of exports outside of Europe.
