The rivier Donau is the second longest river of Europe. It is not only of economic interest for shipping, fishery and tourism, also nature itself is depending on this river. Good maintenance is of great importance. Royal Smals has maintenance of nature as a high priority.
In the bushy area of South-Germany Royal Smals accomplished a project. Using the innovative system of Geotextile dewatering containers the Donau was dredged and dewatered. Damage to nature was districted this way. Royal Smals is not only building for nature, but also with nature.
