Erosion Control
Gabion Slope Protection for Erosion and Embankment Stabilization
Gabions can armor a surface, support a slope toe or form a stepped retaining structure. The correct role must be defined before selecting the basket geometry.

Identify the failure mechanism
- Surface erosion from runoff
- Toe scour or loss of support
- Shallow sliding or raveling
- Deep global instability
- Groundwater pressure or piping
Match the solution
Mattresses can armor broad surfaces, while boxes can create toe mass or stepped retaining support. Neither should be expected to solve deep slope instability without geotechnical analysis and appropriate reinforcement or drainage.
Material durability
On wet slopes or chemically affected sites, polypropylene composite gabion mesh offers a non-metallic route without steel-wire rust. Tensile strength, connection capacity, UV exposure, temperature and construction damage must still be checked against the design.
Frequently asked questions
Will gabions stop every landslide?
No. They can address erosion and provide toe support, but deep instability requires geotechnical investigation and a designed stabilization system.
Why use a filter under slope gabions?
It limits soil migration through the stone while allowing drainage.
