In early 2020, SEGRO, a leading Real Estate Investment Trust, acquired a 450-acre site adjacent to Coventry Airport to expand its UK logistics portfolio. The development, known as Gateway South Coventry, is strategically located near the A45 with direct access to major motorway networks including the M6, M69, M40, and M1. The project involves the construction of 3. 7 million sq ft of industrial and warehouse space, with a total development value exceeding £400 million. A major challenge within the project was the need to construct a new access road linking to the recently developed Rowley Road roundabout. The road alignment passed through a narrow corridor between the UK Battery Industrialisation Centre and Coventry Airport, significantly limiting available construction space. Compounding this constraint, part of the road needed to be built over a former landfill site. Due to environmental and spatial limitations, excavation and removal of the landfill material were not viable options. This presented a high risk of differential settlement, which could lead to long-term structural instability of the road. To overcome this geotechnical challenge, a piled solution combined with a basally reinforced platform was proposed.

Morgan Properties and Bellway Homes West proposed a new residential development on a brownfield site in Newmains, Wishaw, comprising two-storey houses, private gardens, internal roads, drainage infrastructure, and public amenity spaces. During the geotechnical site investigation, two abandoned mine shafts were discovered within the planned public open space, each measuring approximately 2. 3 metres in diameter. The presence of disused mine shafts posed a critical ground stability risk. Without appropriate mine shaft stabilisation measures, there was a high potential for sudden ground collapse, creating a serious hazard for future residents and users of the amenity area. Such a failure could also damage surrounding infrastructure, including roads and drainage systems. Addressing these legacy mining risks was essential to ensure safe residential development and long-term ground integrity. A reliable and engineered solution was therefore required to mitigate the risk of mine shaft collapse, stabilise the ground, and meet regulatory requirements for building on brownfield land affected by historic mining activity.

The Pickford Green Interchange is a strategically important highway infrastructure project on the A45, west of Coventry, designed to enable significant residential and commercial development. The scheme will support the delivery of up to 2,400 new homes and a 15-hectare business park comprising R&D, light industrial, and distribution facilities. Central to the project is the construction of a new grade-separated interchange and overbridge, replacing two existing junctions to improve traffic capacity and safety. A major geotechnical challenge was encountered along the northern approach embankment, where construction was planned over soft ground. These poor ground conditions posed a high risk of differential settlement, a common issue in highway embankment construction that can lead to structural deformation, reduced lifespan, and increased maintenance requirements. Without an effective ground stabilisation solution, the long-term performance and safety of the interchange would be at risk.
