Tidal Defence Project

The Project

Following the work completed in March 2017 to replace piles along the Southtown and Cobholm frontage.

This phase of the project is focusing on refurbishing the existing flood defence walls which already provide a good level of flood protection to extend their life. We will be raising the height of some of the existing flood walls, installing cathodic protection to multiple quay walls and in locations where the existing flood defences are at the end of their life, we will also be constructing new walls set back from the river frontage.


Construction work commenced in October 2019 and is due to be completed in December 2022.  The project is split up into 23 separate works packages that will be delivered at different times throughout the duration of the project. The remaining two works packages are 


These essential works are being carried out on These include installing a new reinforced concrete flood wall at the southern end, demolishing the existing walls and buildings along the perimeter of Gas House Quay and replacing them with a and panel wall with security fencing on top and finally we are raising the entrance road off Malthouse Lane. The works will connect the 3rd River Crossing flood wall on Southtown Road to the new set back flood wall constructed by JBA Bentley in December 2021 on Malthouse Lane.

To enable us to carry out these works safely and efficiently, a lane closure is required on Southtown Road where it meets Beccles Road for approximately 27 weeks from the August 2022. We apologise for any delays and inconvenience this may cause.

The below shows the new alignment of the flood. Further details on the flood wall can be found in our approved planning application on the Great Yarmouth Borough Council planning portal here.



Work has started Wall 112 which consists of the construction of a new sheet piled flood defence wall around the Grist Mill, Critten’s Road which is situated on the bank of the River Yare.

Our access to the site is direct from Critten’s Road, where a temporary parking suspension has been put in place to allow access for large delivery vehicles. Parking will be re-instated on completion of the work.

During May and June 2022 we are preparing the area for the main piling work by installing temporary crane pads and mobilising two 300T crawler cranes required to lift the steel sheet piles into position. Piling activities will start in July 2022 and are due to finish at the end of September 2022. Once the sheet piles are installed the works to fix the braces and undertake all the reinstatement work gives a finish date of early 2023.

Given the location of the work is close to a residential area the piling will be done using a specialist contractor, experienced in the use of silent and vibration free piling techniques. This will help to minimise the impact on local residents as much as possible.
