Ground improvement and stabilisation of a Maritime Quay in St Helier, Jersey, Channel Islands

Ports of Jersey require ground improvement, stabilisation and jacking of the hardstanding slabs c2000m2 for New North Quay, St Helier. \r New North Quay is located in St Helier, Jersey and is a man-made in filled granite structure with a concrete. These works are located on an operational quay, with the only LOLO operations for the Island of Jersey so it is imperative that the disruption to operations is kept to a minimum. \r Ports of Jersey are looking to procure a design and install solution that will need to last a minimum of 7 years. \r The existing underlying infill material is weak, and 'fines' have been washed out due to rising and falling tides. St Helier has a tidal range of approximately 12m. \r
