Topforce at Humber estuary, Stallingborough
Coastal defence work
Led by the Environment Agency, the Humber Estuary Flood Risk Management Study identified an initial package of five schemes with the aim of delivering long-term protection for up to 400,000 people across the Humber estuary.
The project required concrete products that provided long-term durability and time savings in a limited tidal window.
Tarmac supplied around 3,000m3 of its Topforce concrete and 2,000m3 of conventional concrete for the construction of the new sea defence at Stallingborough.
According to Alan Smith, site agent at Birse Coastal, the product is already proving its worth.
Alan Smith said: "Typically, mesh fabric is used on sea wall defence schemes, but the macro-synthetic fibres within Topforce have allowed us to reduce the use of steel mesh fabric on the overall scheme by around 35%. Mesh can easily get exposed and can quickly corrode, so using a material with added fibre is beneficial".
