Trevi secures compaction deal for Swedish port

stockholm norvik hamn

Stockholm Norvik Port has appointed Hercules Trevi Foundations to undertake soil improvement work using dynamic compaction for a new terminal at the Swedish port.

The contract follows on from jet grouting and lime cement column work undertaken by Trevi to consolidate ground in another area of the port.

The dynamic compaction will be applied to a 96,000m2 area that has been reclaimed and ground conditions are predominantly clay sediment from the reclamation work and stone spoil from drill and blast activities elsewhere within the port. Trevi has said that the dynamic compaction will be applied on a grid layout with around 15,500 treatment points that are each designed to consolidate a 10m radius from the point of impact.

Trevi has said that dynamic compaction is rarely used in Sweden but use at the port will help main contractor NCC meet the tight construction programme for the new container terminal.
