Wick drains were installed to evacuate pore water from the dredge fill to induce consolidation and settlement. Using wick drains as a drainage path to reduce the water content also strengthened the underlying soil to accommodate superimposed loads.
To meet the tight schedule, USW operated up to 6 stitchers and 4 pre-drills in extended shifts. Each rig was equipped with a sophisticated system of GPS devices, inclinometers and sensors to capture a real-time record of each wick drain installed. In less than four months, approximately 28,500 individual wick drains were successfully installed, helping to restore and revitalize the port and position it for future expansion.
