This project was undertaken on behalf of Leeds City Council to provide flood protection for the River Aire. Air bags were installed that could be inflated or deflated, as needed to alter the amount of river water that is allowed to flow over them. Part of the design meant that the air pipework had to be fixed to the existing river wall, therefore exposing them to damage from the water and debris suspended in the river during times of high water levels and flows.
The guidelines set out by the Environment Agency meant hardwood timber was selected as the best material for the fenders, Greenheart being the preferred type. We were able to match all the procurement guidelines; profile and drilling the fenders within a short time frame.
