LOCATION: Ancona (AN) Italy
YEAR: 2004
DURATION OF WORK: 11 days
COMMITTENTE: Port of Ancona – South Pier, Dock 22 

Self-propelled cranes with a static working load of 30.00 tons/sq. m operate in the service area. Heavy machinery passing over paving with a subgrade consisting of soil with poor mechanical properties and voids led to subsidence of the pavement: damage, especially depressions, which, if aggravated beyond a certain point, would have prevented the cranes from functioning properly, consequently making the dock unusable.

Customer needs
It was not possible to plan for prolonged work stoppages, so the intervention needed to be quick and minimize the impact on port activities. It also had to fully protect the safety of personnel and guarantee long-term effectiveness of the consolidation work.
Why the Port of Ancona chose Uretek:

• Speed
  Careful planning and programming of the times allowed the work to be completed in just 11 days;
• Non-invasive
  The intervention proposed by Uretek did not require removal of the road structure, and it did not dirty the area or produce waste;
• Localized work
  The Uretek team delimited the work area, allowing regular port activities to continue;
• Continuous monitoring of the work
  Both during and after the intervention, the activities were subject to control by highly qualified personnel using advanced laser technology;
• Exclusive Uretek technology
  The intervention involved the injection of Uretek Geoplus® resin. With its high swelling pressure, it compacts the soil and stabilizes structures;
• Respect for the environment
  Above-ground mixing of the Uretek® resin creates a final inert product that does not release solvents into the soil or possible water tables in the area.

We used our exclusive Uretek Pit Stop® technology (European patent no. 0851064) to thicken the deep subgrade of the quay paving by injecting polyurethane resins with a high swelling pressure.
As the Uretek Geoplus® resin expands, it filled the voids in the soil, compacting the surrounding solid volume and improving its mechanical and hydraulic properties. We then verified the success of the work, making 10 comparative penetration tests before and after the intervention. We stabilized 568 sq. m of paving in 11 days without the need for accessory work or demolition.
