Our crew is getting pretty familiar with the Port of Charleston in South Carolina!
Back in 2016, we installed around 25 million linear feet of wick drains for a container facility at the new Hugh K. Leatherman, Sr. Terminal at the port.
Next, Port Access Road was built between the container facility and the interstate to alleviate the impact of terminal traffic from the surrounding area. To help eliminate excess pore water pressure underneath the roadway, we returned and used a relatively new technique for us, earthquake (EQ) drains, to a maximum depth of 55 feet.
“Earthquake drains were a great addition to our catalog of client solutions because they provide a more cost-friendly way to mitigate liquefaction,” said Frederic Masse, Menard Group USA President. “While many ground improvement solutions in our toolbox can assist with liquefaction, EQ drains are the fastest to install and the least disruptive to the job site and its surroundings.”
As the progress on Port Access Road continues, we'll be returning this summer to install yet another combination of solutions. We'll be supporting 13 embankments and a mechanically stabilized earth (MSE) wall along the road using more EQ drains and over 500 Controlled Modulus Column (CMC) rigid inclusions, a solution we're known for - and one our group has perfected around the world!
The first phase of this project began back in 2016, and the upcoming phase is scheduled to begin in April and wrap up in early 2019.
There are no upcoming events at this time. Please check back soon as something is always in the works!
