Louisiana's landslide exposure is unusual for a low-relief state, concentrated on the steeper loess bluffs along the Mississippi River in the state's northeast and the levee-adjacent embankments DOTD maintains statewide, where soft alluvial and deltaic soils beneath fill embankments settle unevenly and trigger slope movement that standard Gulf Coast maintenance practices haven't fully resolved.
This pattern is consistent with the broader Steep Slope Stability Issues challenges GSI addresses across the state.
GSI's soil nail systems for Louisiana embankments account for the soft alluvial soil beneath the fill, anchoring into whatever competent material exists at depth rather than assuming firm bearing close to the surface. GSI's soil nailing capability supports this step.
Louisiana's high water table and river-influenced groundwater require drainage systems designed around sustained saturation rather than seasonal wet-dry cycling — GSI sizes horizontal drains for continuous, not intermittent, water management. This is one application of GSI's broader Soil Nail Launcher™ expertise.
Soft, saturated Louisiana soils collapse around conventional boreholes readily — the Soil Nail Launcher™ installs reinforcement without requiring the soil to hold an open hole. GSI's horizontal drains experience informs this approach.
This approach is informed by GSI's broader landslide emergency response work across Louisiana.
Engineered for Louisiana's conditions. GSI designs Louisiana slope repairs for sustained saturation and soft alluvial bearing conditions — not the seasonal wet-dry cycle standard slope repair specifications assume. It's backed by GSI's broader general contractors and asset owners capability.
Design/build delivery. A single accountable team delivers design and build — closing the gap between what's designed and what's built.
DOTD specification compliance. Project records and construction methods conform to DOT requirements from initial design submittal.
