The risk of flooding increases through intensified rainfalls and snowmelt. That is why flood protection is a measure for protection of the population and material goods against the floods arising through high water.

Efficient solutions

Successful flood protection can be pursued through vertical filter sections or drainage wells.

Reference: Germany, Elz River estuary/Nonnenweier

 

Project: flood protection at the Elz River estuary/Nonnenweier

Scope of delivers/objective: Flood protection by reacting to high water phases of the Upper Rhine River. Approx. 30 metre-deep DN 2000 gripper boreholes and self-service extension, Rilsan-coated in DN 1200, were created during this project. If the Rhine reaches flooding stage, the water is conducted into retention basis, which in turn are pumped by means of 9 large wells now in existence.
