North Portsea Island Phase 4b Update - Week 10

The concrete for the flood defence wall is poured in three sections: base, the lower wall and then the upper wall. 

The textured wall (moulds) for the lower wall are smaller. The formliners for the upper wall are much larger and a bit more challenging to manoeuvre. 

We have just completed the first upper wall section:

To find out more, see the presentation below where our project manager Caroline Timlett and our environmental specialist Lucy Sheffield explain why we’re adding texturing to the seawall and the importance of engineering ecology into coastal flood defences. Caroline and Lucy were guest presenters during this years New Civil Engineering Future of Floods event.
