What we built

Rock armour at the toe, a new concrete wave wall, and a rebuilt promenade on top.

The hard part

The sea came in twice a day. Concrete could only go in while the tide was out.

How we did it

Each pour was planned to the tide table. The promenade was fenced in short lengths, so most of the seafront stayed open.
