Nebraska's landslide exposure is concentrated in the loess bluffs along the Missouri River and the Platte River valley, where NDOR crews see the same vertical-jointing, moisture-sensitive loess failure behavior found in neighboring Kansas and Iowa — a soil type that dominates Nebraska's slope stability challenges more than any single rock formation does.
It's a recurring example of the Steep Slope Stability Issues conditions NDOR and local owners manage statewide.
GSI's soil nail pattern for Nebraska loess bluffs is designed around the material's characteristic vertical jointing, targeting the joint-controlled failure surfaces loess produces rather than assuming a curved clay-type failure geometry. This is one application of GSI's broader soil nailing expertise.
Because Nebraska loess loses most of its strength when saturated, horizontal drains are prioritized as a primary — not supplementary — stabilization measure on the state's loess bluff corridors. GSI's Soil Nail Launcher™ experience informs this approach.
Disturbed loess collapses around a conventional borehole almost immediately — the Soil Nail Launcher™'s non-excavation approach is often the only reliable installation method on Nebraska's steepest loess bluffs. This draws directly on GSI's horizontal drains work.
GSI's landslide emergency response experience also informs how these Nebraska projects are scoped from the start.
Engineered for Nebraska's conditions. GSI treats Nebraska's loess bluffs as the dominant, distinct soil type they are — engineering around vertical jointing and moisture sensitivity rather than generic slope assumptions. Supported by general contractors and asset owners.
Design/build delivery. Engineering and construction remain under one team — closing the communication gaps that separate design from construction.
NDOR specification compliance. Documentation and construction methods meet state DOT standards from the initial submission.
