We constructed part of the concrete breakwaters floated across the Channel to support the allied invasion.
The Mulberry Harbours were two artificial port facilities designed to supply and support the allied forces in the period following the Normandy landings.
The harbour breakwaters were formed from a series of 200ft-long floating concrete caissons which were towed across the Channel and then sunk into position.
Of the 80 largest caissons 10 were constructed by the company. Eight were built in East India Dock Wet Basin with two part-built downstream before being towed upstream for completion.
