Tidal and coastal
Great Yarmouth
Project: Great Yarmouth Tidal Defence Project
Location: Great Yarmouth, Norfolk
Value: £26.5m
Client: Environment Agency
Great Yarmouth has a history of flooding; in 2013, 9,000 people were urged to evacuate when the highest ever tide was recorded on the town’s river.
We have refurbished 4km of existing flood defence walls, raising defences and installing cathodic protection. Instead of just replacing quay piling as originally proposed, we refurbished existing defences, reducing costs on this element
of works by 47% and carbon by 60%.
Mablethorpe Coastal Outfall
Project: Mablethorpe Coastal Outfall
Location: Mablethorpe, Lincolnshire
Value: £80k
Client: Environment Agency
We replaced old concrete pitched stone haunching along an outfall tunnel after it had badly deteriorated, creating a safety hazard for the general public visiting the beach.
To overcome the limitations of working between tidal windows, we specified materials with quick curing properties but without compromising the quality of the end product. We also programmed the works to take place outside of the main tourist windows.
Chantry Cottages
Project: Chantry Cottages
Location: Goole, Humberside
Value: £6.3m
Client: Environment Agency
Our client had concerns about the stability of the channel bank and foreshore of the Dutch River near Goole. Having pinpointed the area of unstable banking, we delivered a three-phase scheme to reduce the risk of flooding to surrounding areas and properties at times of high tides.
The solution saw us construct a permanent flood defence using a combination of sheet and Continuous Flight Auger (CFA) piling, steel tendons and rock armour to reinforce the embankment.
