Scour Mitigation Across Florida

Florida's scour mitigation needs span the state's extensive coastline and inland waterway crossings, where hurricane storm surge and the state's high water table combine to produce scour conditions FDOT manages across more linear miles of vulnerable infrastructure than almost any other state.

GSI sees this alongside other Washouts & Scour Damage work across the state's infrastructure network.

How GSI Delivers Scour Mitigation in Florida

Riprap and Armor Stone Protection

Riprap and armor stone for Florida bridge crossings are sized for hurricane storm surge conditions across the state's extensive coastal and inland waterway infrastructure network. GSI's bridge solutions experience informs this approach.

Grout-Filled Mattress Systems

Grout-filled mattress systems protect Florida infrastructure from combined storm surge and the state's characteristically high water table conditions. This draws directly on GSI's emergency bridge repair work.

Bridge Foundation Reinforcement

Sheet pile and grouted rock protection at Florida bridge foundations addresses scour from both routine tidal and storm-driven flow across the state's extensive waterway crossings. GSI's coastal and bluff stabilization capability supports this step.

Where relevant, water infrastructure is factored into the Florida project plan from day one.

Florida Scour Mitigation Process

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

Step 1

Site Assessment

GSI engineers evaluate conditions and severity at your Florida site.

Step 2

Root Cause Investigation

In-house geologists investigate the specific conditions driving the issue, referencing Florida's Florida Plateau karst limestone and coastal sand deposits.

Step 3

Engineered Solution Design

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

Step 4

Design/Build Execution

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

Warranty

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

Why Florida Trusts GSI for Scour Mitigation

Engineered for Florida's conditions. GSI's Florida scour mitigation is scaled for the state's uniquely extensive exposure — more vulnerable coastal and waterway infrastructure miles than nearly any other state in this program. This is reinforced by GSI's work in transportation infrastructure and engineers.

Design/build delivery. Engineering and construction remain under one team — preventing the disconnects between engineering and field execution.

FDOT specification compliance. Documentation and construction methods meet state DOT standards beginning with initial documentation.

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!!

Geohazard Mitigation for Transportation in the Mid-Atlantic

Hey Jennifer,

I just wanted to say how much I enjoyed working with you guys on [our project]. Under the circumstances with that big of a job, and traffic volume that was being detoured it was a little stressful, however you all were so easy to work with, it made my job easier! Just wanted to thank you and Ryan for keeping me informed weekly and sometimes daily. Sara did an amazing job with the drill pattern and the engineering side of things. Kyle is one of the best superintendents I have worked with, he is good to his guys and got a lot of work done due to his ability to plan ahead and coordinate. Great experience for me and I really enjoyed working with you all, looking forward to our next job sometime. Please let everyone on the crew know that I really appreciate all their hard work, pleasure meeting everyone!

THANK YOU!”

Project Support for Water and Power in California

As told by GSI Project Development Engineer: We are currently close to finishing one of five sites proposed for repair to the [local Water and Power Agency]. The agency folks were very impressed with GSI’s professionalism and support during the repair procedures. Our approach to the project, our field crew’s commitment to safely, our expertise in what we do, and our continuous involvement in the project at multiple levels all contributed to their positive feelings about GSI.
