Concrete sea defence walls

In the harsh environmental conditions experienced in marine and coastal applications, our precast concrete sea defence walls are designed to perform well with outstanding durability and aesthetic quality of factory produced elements, giving the suitability necessary for marine environments.

All our marine and coastal defence wall units come with the option of GRP (Glass Reinforced Plastic) reinforcement, which is resistant to the corrosive attack by salts in seawater and offers some important benefits over steel rebar.

GRP reinforcement has an equal or greater tensile strength than that of steel but is a quarter of the weight of a steel reinforcing bar. With a good impact resistance, it has excellent static and dynamic fatigue resistant properties and is electrically non-conductive with low thermal conductivity.

It is possible, subject to design criteria, to apply an aesthetic finish to the product that will blend into the marine environment. Using the most up to date designs in rubber matting any appearance can be given to precast concrete, and more importantly, this finish can be repeated time after time in a factory controlled environment.

Depending on your specification we can design a specialist marine concrete mix in accordance with BS EN 206-1 which can be used to extend the life of the finished units, to ensure that the wall can withstand the test of time and the harshness of the tidal environment. Alternatively, if you have your own mix design we will happily work with you to achieve the desired finished product.

Precast Concrete Sea Walls – Case Studies

Poundfield Precast has been involved in a number of high-profile sea defence projects throughout the UK. One of the advantages of precast concrete in sea walls is its resistance to impact and ability to withstand the constant wetting and drying caused by the tides. Read more about some of the coastal management projects we have been involved in.

Whitley Bay – Bespoke Sea Defence Wall

To protect the homes, businesses and roads of Whitley Bay, a new rear sea wall was built. The new sea wall will ensure there is no coastal erosion into Whitley Bay in future years. Poundfield supplied 1,800 bespoke sea defence wall panels to the project, each featuring a specialist bespoke patterned finish applied during the casting process.

Hartlepool Headland – Concrete Sea Wall

With rising sea levels, the existing 100-year-old sea defences were often overtopped during storms, as well as being susceptible to storm damage and erosion. As part of the coastal protection development plan, 2km of sea wall will be strengthened over a five-year period. Poundfield supplied nearly 4,000 individual precast pieces to the project, including 1,075 concrete capping beams.

Cockenzie – Sea Defence Structure

A new sea wall was required at Cockenzie along Scotland’s east coast to protect a new housing development. We delivered 43 L-blocs to the site to create the wall above the tidal break. To fit in with the local area and comply with planning requirements, the L-Blocs were all cast incorporating a Reckli or rough surface finish.
