Oosterschelde stormflood barrier is with its 9 kilometres length the largest stormflood barrier in the world protecting The Netherlands from the sea. It has been built after the big flooding disaster in 1953 that took the life of 1836 humans. After winning the land back from the sea it was decided to protect the land that was about 5 meters below sea level as never protected before by stormfloodbarriers.
Since the building of this particular barrier the sea is attacking the barrier every day. Therefor the maintenance is the most important factor to keep it in good condition. This is not easy for the people working on the coating during the weather season. They have been working in 1 meter of seawater. By making a special inflatable seal in only 40mm wide with expansion possibility of 70 mm, we succeeded to make it a flexible moving dry area.
