Seawall - Wenduine


The new sea wall in Wenduine was officially opened on 19 June 2015. The sea wall  is now safer, wider and more attractive. The new dyke has a road and promenade with room for terraces. Two flood defence walls were constructed to hold back breaking waves. One wall – a secant wall topped by an exposed-concrete parapet – leans in the direction of the beach. The second (landward) wall parapet has the shape of a bench and was also built on top of a secant pile wall. In addition, the Rotunda was renovated and reinforced. A new windscreen, a platform and new surfacing with a petanque area, a sports field and a skate park were added.

The works also included:
• Staged breakdown of the existing sea wall.
• Widening the sea wall by 3 and 10 metres.
• Construction of a seaward flood defence wall with a concrete retaining wall.
• Construction of a landward flood defence wall by building a concrete retaining wall in the shape of a bench.
• Planning, construction and maintenance of mobile flood defences which have to close off the uniform openings between the landward flood defence.
• Constructing a new sea wall with clay pavers.
• Building of a platform construction on the Rotunda with a sea-retaining function.
• Modification to the windscreen on the Rotunda
• Renewal of the roof sealing of the underground car park under the Rotunda.
• Provision of street furniture on the sea wall and the Rotunda.
