Dagenham wharf has been successfully dredged recently to maintain the berth for ongoing deliveries of marine aggregates and hard rock cargoes.

The project involved the removal of several hundred tonnes of silt that had accumulated at the site through natural deposition. The work used water-injection dredging, which is highly effective in removing recently deposited fine sediments that consist of fine sand, silt and clay particles. The process uses water jets to fluidise riverbed silt on a flowing tide where it disperses naturally. This technique also removed the requirement to dump the dredged sediment to a licensed disposal site.

Through coordination of the dredging permission process and close liaison with the dredging contractor, CEMEX were able to undertake the work on a joint mobilisation, saving 44% of the original proposed cost.  The depths at the wharf will continue to be monitored regularly.
