Surcharge Testing

The Louisiana International Terminal is in the planning and design phase. Part of that process involves making sure we have a strong foundation on which to build. Our soil studies have given us valuable insight and a path forward. The next step in the development process is to validate those studies by performing different field tests. The first is a series of surcharge tests.

What is Surcharging?

Surcharging is a proven process that helps the ground settle faster. Here’s how the process works:

By surcharging, we can make the ground more compact and create a sturdier foundation for the terminal.

Why the Need for Surcharge?

Before we construct the Louisiana International Terminal, we need to make sure we have a strong foundation on which to build.

The U.S. Army Corps of Engineers has approved these tests, and the Port of New Orleans has mitigated for them. The Louisiana International Terminal is currently undergoing an environmental review process, as required under the National Environmental Policy Act (NEPA), before permits can be issued and construction can begin.

Test Site Locations

What Can You Expect?

While constructing the two test sites and access road, crews are onsite weekly, Monday through Friday, from 6:00 am - 5:00 pm. Saturdays will be weather-related makeup days.

Test Surcharge Site 1 (TS-1):

Measures approximately 325' x 325'
Includes prefabricated vertical drains, aka “wicks,” about 65' deep
Will have a mound of river sand up to a height of 18'

Test Surcharge Site 2 (TS-2):

Measures approximately 150' x 150'
Will reach a height of approximately 10'
