Since 1932, the Afsluitdijk has been one of the Netherlands’ most famous hydraulic engineering projects. The dike connects North Holland with Friesland and protects the country from the Wadden Sea. The lock complexes at Den Oever and Kornwerderzand drain excess water from the IJsselmeer into the Wadden Sea.

Steel Preservation of Lock Gates on the Afsluitdijk
In 2008 and 2009, SealteQ fully treated 48 floodgate doors from the Afsluitdijk in our booth in Bergum. Seventeen years later, it’s time for another round, commissioned by Rijkswaterstaat. In 2025, we delivered the first two gates, to the client’s complete satisfaction. Six are scheduled for 2026, with more to follow in the years after that.
The work includes, among other things:
- Thorough cleaning of the lock gates
- steel blasting
- applying a new coating
Once the work is complete, the lock gates will be returned to the Afsluitdijk in like-new condition. This will ensure they remain well protected against the effects of water for many years to come.
