Controlling lateral movement and consolidating soft deposits
Port of Gulfport
The Mississippi State Port Authority (MSPA) at Gulfport needed to protect its restored and rebuilt facilities from future storm damage after Hurricane Katrina had significantly damaged its original ones. During the first phase of the project, the West Terminal had to be elevated to 25 feet above sea level, plus MSPA wanted to place an 84-acre addition on soft dredged fill. In addition to being unstable, the fill had wide areas of debris scattered throughout from the clean-up effort after the hurricane.
On land or by barge, Menard’s flexible working style respects the environment with cost-effective ground improvement solutions that ensure global stability.
Over 16 million linear feet of wick drains (approximately 28,500 individual wick drains) were able to accelerate consolidation of the fill—not only expediting construction, but also limiting long-term settlement. These wick drains evacuated pore water from the dredge fill and created a drainage path for its water content. 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.
U.S. Wick Drain operated up to 6 stitchers and 4 predrills in extended shifts to install this ground improvement solution in less than four months.

“We aren’t afraid to take on complex projects. In Gulfport alone, we worked through three phases with two different contractors and the port itself, performed pre-drilling and installed over 263,000 wick drains while working two shifts.”Steve Darnell, Project Manager, Port of Gulfport Project
