Located in the Outer Hebrides, the Isle of Benbecula is one of the most westerly and exposed locations in the British Isles. The island faces relentless Atlantic Ocean conditions, including storm-force winds, high-energy wave action, and ongoing coastal erosion. Over time, this erosion began to threaten the south-western boundary of Benbecula Airport, an essential transport hub providing a vital connection between the island and mainland Scotland. As the shoreline receded, the integrity of the airport’s infrastructure and operations came under increasing risk. Highlands and Islands Airports Ltd required a long-term coastal defence solution capable of mitigating erosion, protecting critical assets, and ensuring the continued safe operation of the airport in a highly aggressive marine environment.

In early 2020, leading Real Estate Investment Trust SEGRO acquired a 450-acre site adjacent to Coventry Airport as part of its strategy to expand its UK logistics portfolio. The development, known as Gateway South Coventry, is strategically located south of the city near the A45, with excellent access to major motorway networks including the M6, M69, M40 and M1. The scheme represents a significant logistics and industrial development, delivering approximately 3. 7 million sq ft of warehouse and industrial space with a gross development value exceeding £400 million. Due to the scale of the project, effective surface water management was a critical requirement. A comprehensive Sustainable Drainage System (SUDS) was implemented across the site to manage runoff and reduce flood risk. This included multiple large attenuation ponds designed to collect surface water from the piped drainage network. Headwalls were installed to discharge water into these ponds; however, the concentration of flow at these outfalls created a risk of erosion. During heavy rainfall and storm events, discharge velocities were expected to reach up to 3. 8 m/s. These high-energy flows posed a significant threat to the clay-lined pond basins, with the potential to cause scouring, material loss, and long-term damage to the drainage infrastructure. To ensure the performance and longevity of the SUDS system, a durable and high-performance erosion protection solution was required at each headwall outfall location.

At Exley Bank, the project presented a complex slope stabilisation and erosion control challenge requiring a durable, long-term solution. The existing slope was highly susceptible to soil erosion, posing risks to structural integrity and environmental stability. In addition to engineering performance, the scheme needed to support vegetation growth and deliver a natural, visually appealing finish that aligned with environmental and planning requirements. Conventional slope protection methods were unlikely to provide the necessary combination of erosion resistance, topsoil retention, and ecological integration. The design team also needed a solution that could be efficiently installed while coordinating multiple contractors on site.
