Helping to keep the Eastern Scheldt Storm Surge Barrier in top condition

At nine kilometres in length, the Eastern Scheldt Storm Surge Barrier (Oosterscheldekering) is the largest of the thirteen Delta Works dams protecting the Netherlands from North Sea flooding. The giant structure contains 62 steel doors, each 42 meters wide, and maintaining them is no easy task.

The challenge of blasting and repainting the gates rests with Van der Ende and GSB, two leading specialists in the protection of steelwork against corrosion. It is an eight-year project in tough conditions, during which time the Oosterscheldekering must remain fully operational. Work also needs to be carefully timed to avoid the storm season.

Sibelco is proud to supply Bekagrit iron silicate abrasive (copper slag blasting grit) for this challenging project, helping to ensure excellent surface preparation results as the gates are fully grit blasted and repainted. For flexible storage, we have also provided silos painted in the brand colours of Van der Ende and GSB.

We are delighted that the project team depend on Sibelco and Bekagrit, and we’re proud to be contributing to the upkeep of such an incredible piece of civil engineering to keep the Netherlands safe from flooding.
