Tonnes of rock delivered
to Stallingborough
More than 67,000 tonnes of rock have now been delivered to site as part of the Stallingborough Sea Defence Improvement Scheme on the Humber estuary’s south coast
A Jackson team, who is delivering this third phase of the project on behalf on the Environment Agency, began working on the scheme at the start of Summer 2023.
Once complete, approaching 100,000 tonnes of rock armour will have been installed along this 4.5km stretch of coastline near Grimsby coupled with various revetment repairs and landscaping. The defences will benefit 2,300 properties, nationally important infrastructure, vital industry, and areas outlined by North East Lincolnshire Council for future development.
The rock arrives in barges, each carrying 4,500 tonnes, from Oban on the West coast of Scotland and is delivered direct to Immingham docks – a short distance from where the Stallingborough coastal defences are being constructed. All the remaining large rock is due to arrive in the coming months, and the majority is due to be placed by October 2024.
Because the rock is being placed on the seaward side of the flood defence, the existing flood embankment splashdeck has had to be widened to facilitate the use of long-reach excavators and tracked dumpers placing and delivering the rock from remote localised compounds. The rock is placed to comply with minimum laying density specifications.
