Flood and Sea Defence

Our Projects

Working alongside main contractors, local authorities and the Environment Agency, W&B Civil Engineering has played an integral role in the delivery of major flood alleviation and coastal defence schemes.

These highly technical projects require specialist knowledge of working in challenging environments, often within tidal zones and areas subject to strict environmental controls. W&B’s experienced teams have delivered critical infrastructure including sea-front drainage systems, large flood alleviation culverts, reinforced concrete aprons and associated coastal protection works.

Notable schemes include the Fairhaven & Church Scar Coastal Defence Scheme in Lytham St Annes, delivered alongside VolkerStevin as part of the VBA joint venture for Fylde Council and the Environment Agency. The project involved the construction of new coastal defences designed to protect thousands of homes and businesses from coastal flooding and erosion along the Fylde coastline.

W&B has also supported the delivery of the East Rhyl Coastal Defence Scheme in North Wales, working with Balfour Beatty on the installation of drainage infrastructure and reinforced concrete works as part of the wider flood defence programme protecting the Rhyl coastline and surrounding communities.

These projects demonstrate W&B’s capability to operate within complex coastal and flood risk environments, delivering specialist drainage and civil engineering works that contribute to the long-term protection of communities and critical infrastructure.

Flood and Sea Defence

East Rhyl Costal Defence Scheme

Date:	2025 - 2025
Value:	£1.4 Million Labour & Plant
Location:	Rhyl
Client:	D Morgan / Balfour Beatty

The East Rhyl Coastal Defence Scheme was delivered to strengthen and enhance the existing sea defences along the North Wales coastline, providing long-term protection for local communities, infrastructure and property from coastal flooding and erosion.

Working alongside Balfour Beatty and D. Morgan plc, W&B Civil Engineering undertook key elements of the early construction phase of the revetment structure forming part of the new coastal defence system.

Our scope of works included the installation of blinding, construction of the reinforced concrete toe beam and the installation of the first row of the revetment wall. These works formed the critical foundation of the coastal protection structure designed to dissipate wave energy and stabilise the shoreline.

Operating within a tidal working environment presented a number of logistical and engineering challenges. Works had to be carefully programmed around tidal windows to allow safe access to the working area, while excavation and preparation works included the removal of existing rock and material to form the required foundation levels for the new defence structure.

Through careful planning, experienced site teams and the use of specialist plant, W&B successfully delivered these works within the tight tidal constraints, contributing to the successful progression of this important coastal protection scheme.
