Rohde Nielsen A/S has for years carried out reclamation by the „Rainbow Method”.

This method has now been developed to include a precise and very cost effective method for „filling” building caissons. Sand filled caissons are used as break waters, foundation for bridges and windmills and other coastal protection.

A few examples of successful applications: Brighton (UK), the pillars of the great belt bridge (Denmark), Tanger (Morocco), Gijon (Spain).
