Scour Mitigation Across North Carolina

North Carolina's scour mitigation needs have intensified with recent hurricane events, and NCDOT bridges across the state's river systems face storm-driven scour that has exposed gaps in older infrastructure's original design assumptions, particularly following major storm events in recent years.

It's a recurring example of the Washouts & Scour Damage conditions NCDOT and local owners manage statewide.

How GSI Delivers Scour Mitigation in North Carolina

Riprap and Armor Stone Protection

Riprap and armor stone for North Carolina bridge crossings are sized for updated hurricane storm intensity data, reflecting design conditions that have shifted since much existing infrastructure was originally built. This is one application of GSI's broader bridge solutions expertise.

Grout-Filled Mattress Systems

Grout-filled mattress systems protect North Carolina infrastructure from the combined river flow and storm surge scour recent hurricane seasons have demonstrated. GSI's emergency bridge repair experience informs this approach.

Bridge Foundation Reinforcement

Sheet pile and grouted rock protection at North Carolina bridge foundations addresses scour damage exposed by recent significant storm events. This draws directly on GSI's coastal and bluff stabilization work.

GSI's water infrastructure experience also informs how these North Carolina projects are scoped from the start.

North Carolina Scour Mitigation Process

GSI follows a systematic five-step process to deliver scour mitigation solutions in NCDOT corridors and beyond.

Step 1

Site Assessment

GSI engineers evaluate conditions and severity at your North Carolina site.

Step 2

Root Cause Investigation

In-house geologists investigate the specific conditions driving the issue, referencing North Carolina's Blue Ridge metamorphic gneiss and Piedmont granite terrain.

Step 3

Engineered Solution Design

Custom design matched to North Carolina's site-specific geology, hydrology, and infrastructure loading.

Step 4

Design/Build Execution

One team executes the engineered solution under a single NCDOT-ready contract.

Performance Warranty

Design/build/warranty coverage on every scour mitigation solution installed in North Carolina.

Retaining Wall Repair for Commercial Property in Ohio

I wanted to let you know how impressed we were with your company. Time will tell how well it all worked, however, the professionalism and quality of your team was most obvious. I truly believe we could not have picked a better company for this large endeavor. I was there yesterday showing it to our owner, and was quite proud of the work you did. Everything you promised, you delivered. And though there were a couple snafus, based on a job this large, it was beyond minor and also you made it all right in the end. Thank you for that. In speaking with Tammie, our Property Manager and Dave--the quality of your guys working was top notch.

Again, ask me years from now how it is working, but if ever we had another job with your name on it, it would be a pleasure and honor to work with you again!

Landslide Repair for Infrastructure in California

“I would like to thank you and the county for repairing the road slide on Dunne avenue. The repair is excellent and the contractors were very efficient and skilled. You personally did a great job of providing information about the status of the project. My family appreciates your efforts.”

Erosion Control for Water Infrastructure in Minnesota

I am sending this to you from Duluth Minnesota where 4 of your employees just finished working on a wall they had put in for us previously. That was a few years ago after Duluth suffered a flood. We are on Lake Superior and St. Louis County wanted to help stop erosion. The guys worked during the rain and just kept on going, like little Energizer bunnies. Nice fellows, all of them!! They are certainly a credit to your company and I feel it is always good to give thanks to people for a job well done. Please let them know how much we appreciated their dedication to get the job done. We will always wish you and your team good days ahead!!
