Restoration of quay

Vivescia used to have an unloading quay in the town of Mouy-sur-Seine.
The structure in sheet metal piling measured about 40 metres.
The back sheet piling upstream and downstream of the quay were in poor condition and the upstream and downstream embankments were severely eroded.
So it became necessary to restore the structure.
