New Street in Henley-on-Thames is a key transport route, connecting the northwest of the town across Henley Bridge over the River Thames դեպի the eastern side. As one of the main arterial roads, it is subjected to consistently heavy traffic loads, leading to accelerated wear and deterioration of the carriageway. The road is historically significant and constrained by stone setts along both sides, which limit reconstruction options and require a sensitive yet effective pavement rehabilitation approach. By July 2022, the asphalt surface had reached a critical condition, with extensive failure requiring urgent carriageway maintenance. Oxfordshire County Council initiated resurfacing works but identified a major risk associated with standard asphalt overlays, reflective cracking. Without intervention, cracks from the underlying layers would propagate through the new surface, reducing pavement life and increasing long-term maintenance costs. To address this, the Council sought a proven asphalt reinforcement solution capable of extending pavement lifespan and improving performance under heavy traffic conditions.

The North Bexhill Access Road is a 2. 4 km single-carriageway infrastructure project located in East Sussex, South East England. Designed to unlock future employment land and stimulate economic and housing growth around Bexhill-on-Sea, the scheme represents a critical investment in regional development. Construction began in July 2016, progressing in phases with completion targeted for late 2018. A key engineering challenge on the project was the construction of road embankments over weak and highly variable ground conditions. In Phase 1, completed in winter 2016, the embankment was founded on soft soils and required basal reinforcement using high-strength uniaxial geogrids (Paralink) to ensure long-term stability. Phase 2 introduced even more complex geotechnical conditions, with deep alluvial deposits and peat lenses present across the site. To address these issues, the embankment design incorporated ground improvement columns combined with a Paralink geogrid acting as a load transfer platform, enabling the safe distribution of loads over compressible soils. In addition to embankment construction, the project required the safe operation of heavy construction plant, including mobile cranes and piling rigs. This created a demand for robust temporary haul roads and working platforms capable of supporting high loads without excessive settlement or failure. The underlying soil profile, consisting of soft-made ground, silty clay, alluvium, and peat layers extending to depths of over 8 metres, posed significant risks to construction safety and programme delivery.

Telford Homes acquired the Rotherhithe New Road site for £19 million to deliver a major educational development in London, including a new Southwark Free School and a sixth-form centre for the City of London Academy. Scheduled for completion in 2018, the project required careful ground engineering due to challenging subsoil conditions. The site is characterised by soft clay, which presents low bearing capacity and a high risk of settlement. These ground conditions necessitated the use of a pile foundation system to ensure structural stability. However, constructing a traditional granular piling mat over weak subgrade would typically require significant thickness, increasing construction costs, material usage, and programme time. The contractor therefore required a more efficient ground improvement solution that could enhance load distribution while reducing the thickness of the working platform.
