Coronavirus: council service information and advice

Information about changes to council services as a result of coronavirus

Work to repair a small number of coastal defence wall sections along Tipner Lake began this week and will be completed by the end of September.

There have been images circulating on social media regarding the new seawall which has been built along sections of Tipner Lake. These images show some isolated crumbling of the concrete near the join between wall sections.

The project team, being led by the Eastern Solent Coastal Partnership on behalf of Portsmouth City Council, the Scheme designers and the contractors delivering the North Portsea Island Coastal Defence Scheme are aware of this issue which is purely cosmetic and does not degrade the current structural integrity of the wall.

Bryan Kennedy, Southern Division Director for Knights Brown, the Scheme contractors, said "our work on the sea defence wall has been a great source of pride to Knights Brown over the three years we have been on site. We are disappointed that some spalling has occurred in some sections and are working closely with our specialist contractor, the designer and Portsmouth City Council to identify the root cause of the issue. We are fortunate to have a positive working relationship with all parties on the project and have agreed the repair work which will take place."

These repairs involve a localised hydro-demolition of the affected sections of wall before these are re-cast. Some areas will be fenced whilst this work takes place and supervised by a banksman. This work began on Monday 2 September and should be completed by the end of the month. We thank the public for their patience during the work period.
