highway gabion erosion control

Engineered Erosion Protection for Transportation Infrastructure

Our highway-grade gabion systems provide permanent erosion control solutions specifically designed for transportation infrastructure. meeting DOT specifications and withstand the challenging conditions of highway environments, including vibration, de-icing salts, and water runoff. These engineered systems protect slopes, channels, and embankments while reducing long-term maintenance costs.

Highway-Specific Applications:

1. Slope Protection Systems

• Cut Slope Stabilization: 2:1 to 1:1 slope ratios meeting DOT standards

• Fill Slope Protection: Embankment security for new construction

• Landslide Prevention: In geotechnically challenging areas

• Rockfall Protection: Barrier systems for mountainous terrain

2. Drainage Management

• Channel Linings: For ditches and swales alongside highways

• Culvert Outlet Protection: Prevents scouring at drainage endpoints

• Stormwater Management: Energy dissipation in retention areas

• Bridge Approach Protection: Prevents erosion at abutments

3. Embankment Security

• Roadway Edge Protection: Shoulder stabilization systems

• Noise Barrier Foundations: Secure bases for sound walls

• Retaining Structures: For limited right-of-way areas

• Landslide Repair: Emergency slope stabilization

Highway Performance Features:
