March 2026 - Emergency repair works
Between the evening of Wednesday 4 February and morning of Thursday 5 February 2026, high tides and strong winds caused around 20cm to 30cm of beach material to be eroded from the base of the Hunstanton seawall. This resulted in tidal action forming a void under the promenade deck and resulted in partial collapse of an asphalt area of promenade.
Further investigations identified that a large void had developed beneath the promenade. Current estimates of its size is 3.5m deep, 4m wide and 15m long. You can view some images of the void in our Hunstanton Void Inspection document.
Emergency works fill the void commenced on Monday 2 March 2026 and will include:
- Any gaps in the blockwork seawall mortar joints and concrete promenade pad edges being sealed to prevent concrete from seeping out from behind and onto the beach
- Trench piling installed at the base of the seawall directly in front of the void to prevent concrete from seeping out beneath the seawall and onto the beach
- Access holes cored into the promenade to allow concrete to be poured in
- Concrete poured to fill void in 0.5m and 1m deep layers to allow it to settle and cure between pours. Access holes will then be sealed once the concrete pour to fill the void is complete.
These works will be undertaken by Southbay Civil Engineering and are expected to take a minimum of two weeks to complete – although this may need to be extended if any additional works are required (e.g. the void is larger than currently anticipated).
While works take place, the current 140m cordon for both pedestrian and vehicles on the promenade around the void will remain in place. Please do not enter the area of promenade which is closed and use alternative routes to access the remainder of the promenade and beach.
