Louisiana's Mississippi River levee system, Intercoastal Waterway, Lake Pontchartrain rely on earthen embankments and levees that protect communities and infrastructure from flooding. These structures face threats from seepage that erodes internal soil, slope instability under sustained flood loading, settlement from foundation consolidation, and animal burrowing that creates preferential seepage pathways. When a levee fails during a flood event, the consequences are catastrophic and immediate.
Most levee failures begin with undetected internal erosion—seepage that carries fine soil particles through the embankment, creating voids that progressively weaken the structure until external signs appear. By the time surface evidence is visible, the internal damage may be extensive.
Soil nailing reinforces embankment slopes from within—driving steel reinforcement through the soil mass to resist the sliding forces that develop under sustained flood loading. GSI's Soil Nail Launcher™ installs nails without the excavation that would further weaken an already-stressed embankment.
High-consequence levee sections—protecting population centers or critical infrastructure—require active restraint. Ground anchors apply permanent stabilizing forces to the embankment, resisting the driving forces that develop during design-level flood events.
Internal erosion—piping—causes more levee failures than overtopping. GSI designs seepage cutoff walls, relief wells, and filter systems that control seepage without creating hydrostatic pressure buildup that could trigger slope instability.
No-excavation reinforcement. The Soil Nail Launcher™ installs reinforcement without the excavation that would further weaken a stressed embankment.
Flood-stage design loading. Every stabilization is engineered for sustained flood conditions—not fair-weather analysis.
Seepage control integration. Internal erosion prevention is standard in every levee repair, not an optional add-on.
Emergency flood-season capability. Rapid deployment when rising water reveals embankment distress that cannot wait for the next dry season.
