Project Description

The project involved the removal of relic structures and the remediation of the site to eradicate free flowing hydrocarbon contamination and impacted soils. The remediation process involved the excavation of the contaminated ground followed by the controlled treatment of the spoil to reduce the level of contamination to site target levels denoted by the Environment Agency. The works also involved the re-engineering of the site to formation level which included the modification of the soil with cement stabilisation, all to allow the construction of Europe’s first 3-storey, vehicle access warehouse.

  • The works were undertaken under the guidance of specialist UXO consultants to allow the safe excavation of the site as the site was heavily bombed in WW2
  • Tidal water was a significant problem on this site as the site is less than 200mtrs away from the River Thames causing working hours to be restricted and implementation of water management solutions
  • 4,000 m3 of hydrocarbon-impacted soils were remediated and reused on site
  • 38,000 m3 of material was re-engineered using cementitious binders
