Special planning and cautious implementation is required for projects that entail intervention in bodies of running water. After all, the work involved here impacts on a complex ecosystem with similar implications for man, fauna and flora. Here Trimodalbau offers comprehensive know-how in the field of excavation and in the fabrication of underwater concrete linings for inland waterways and dyke construction, as well as compensation and renaturation measures. When it comes to hydraulic steelwork, we can draw on a wealth of accumulated know-how in the fields of steel construction, hydraulic construction and engineering, for successful implementation in canal bridge projects.
