Erosion control on highway cut slopes, stream crossings, and embankment fills is not just permit compliance — it's structural when inadequate surface protection allows concentrated flow to undercut a retaining system or scour a bridge abutment. When your erosion control sub's scope doesn't address the geotechnical erosion driver, the regulatory and structural consequences land on your prime contract.
GeoStabilization International approaches erosion control as a geotechnical scope — identifying the erosion mechanism, sizing the protection system to the hydraulic load, and installing systems designed to remain stable under design storm events.
GeoStabilization International provides engineered erosion control subcontract services for slope face protection, streambank stabilization, scour mitigation, and seepage control on infrastructure and commercial projects.
Cut slopes and fill embankments exposed by highway construction require surface protection that survives design rainfall events. GSI installs engineered erosion control systems including permanent geotextile, rock slope protection, and shotcrete facing designed to your site's hydraulic conditions.
Streambank erosion threatening roadway infrastructure and bridge abutments is addressed through revetment, bioengineered systems, and anchored rock armor installed by our water resource crews.
Bridge foundation scour is addressed through engineered scour countermeasures including riprap aprons, concrete mattress, and articulated block systems. GeoStabilization International coordinates installation with your bridge substructure schedule and in-water work window.
Most erosion control subs install what the plan specifies — silt fence, seeding, and straw wattles. Those temporary BMPs satisfy permit compliance but don't address the underlying erosion mechanism: concentrated flow velocity, seepage, or slope geometry generating erosion energy faster than surface revegetation can establish. GeoStabilization International designs permanent protection for the hydraulic condition driving erosion.
Our protection designs are sized to the actual hydraulic condition, documented with calculations that support regulatory agency review — not minimum compliance specifications.
