The right-bank flood protection dike on the Schwarze Elster has an excessively high permeability due to its high organic content and soil density and is therefore being comprehensively renewed. The aim of the measure is to restore the dike’s protective function over the long term while also strengthening the region’s infrastructure.

The works include, among other things, the removal and processing of approx. 11,000 m³ of topsoil, the removal of the existing dike amounting to around 130,000 m³, and the processing of approx. 95,000 m³ of excavated material. For the new structure, a dike support body of approx. 87,000 m³ and a drainage layer of approx. 11,500 m³ are being constructed; the foundation area covers around 53,000 m². In addition, a cycle path of around 4 km is being built along the dike crest, providing clear added value for the region. Existing structures are also being dismantled, including two bridges, DN 2200 siphon pipelines, and a weir structure. Furthermore, a new gauging station building is being constructed for the Saxon State Agency for Environment and Agriculture, including masonry works, precast reinforced concrete elements, a measuring section, and a reinforced, paved gauge shaft. The project is rounded off by replacement planting of approx. 4,400 shrubs and plants.

For the new dike construction, material from the existing dike is first removed and processed using a drum screen to eliminate contaminants. It is then mixed with bentonite powder, installed in layers, and compacted. The final dike profile is formed with precision using GPS-controlled technology.

With this measure, SWIETELSKY is making a significant contribution to ensuring long-term flood protection along the Schwarze Elster while supporting the sustainable development of the region’s infrastructure.
