• Installation of 9,600 lime cement columns with a
diameter of 800 mm, for a total of approximately
205,000 linear metres.
The Port of Stockholm, located in the historic
centre of the city has always contributed to traffic
congestion in urban areas. That’s why Swedish
authorities decided to build a new commercial dock in
an area mostly dedicated to the storage of containers,
the Norvik Port.
The area partially encompassed a zone made up of
filling material, which sediments were characterized by
a variable granulometry ranging from clay to boulders.
To support the heavy loads of the port, it was necessary
to consolidate the soil under the port yards through
the installation of lime cement columns and jet grouting,
while heavy dynamic compaction was used for the
crushed rock backfill.
After the successful completion of the consolidation
works, Trevi was awarded an additional contract for
The second phase required heavy dynamic compaction
over an area with an extension of approximately
96,000 m2 characterized by a regular grid of about 15,000
This technology, which is rarely used in Sweden,
satisfied the project requirements and the tight work
schedule, proving to be efficient and functional.
