What is Gabion Mesh?
Gabion mesh, also known as rock cage mesh or gabion basket mesh, is a double-twisted hexagonal wire mesh container filled with rocks, stones, or other suitable materials to create flexible, permeable structures for erosion control, retaining walls, and landscaping applications. The word “gabion” derives from the Italian “gabbione,” meaning “big cage.”
This time-proven technology combines the strength of steel wire mesh with the mass and durability of stonefill, creating structures that blend harmoniously with natural environments while providing effective civil engineering solutions.
Key Features
- Flexibility: Wire mesh containers conform to ground movement and settlement without structural failure
- Permeability: Open structure allows water to pass through, eliminating hydrostatic pressure buildup
- Durability: Galvanized or PVC-coated wire provides decades of service life in harsh environments
- Erosion Resistance: Heavy stonefill absorbs and dissipates water energy, protecting against scour and erosion
- Environmental Integration: Stone-filled baskets blend naturally with landscapes; vegetation can grow through mesh openings
- Cost-Effective: Local stonefill materials reduce transportation costs; simple installation minimizes labor expenses
Types of Gabion Structures
- Gabion Baskets: Rectangular wire mesh containers filled with stone; most common application
- Gabion Mattresses: Low, wide containers for surface erosion protection; also called Reno mattresses
- Gabion Walls: Vertical or near-vertical retaining structures using stacked gabion baskets
- Gabion Colums: Cylindrical mesh forms for architectural and structural applications
- Decor Gabions: Smaller mesh panels for garden landscaping and decorative features
Retaining Wall Applications
- Infrastructure Retaining Walls: Highway and railway embankment stabilization
- Commercial Retaining Walls: Parking lot and building foundation support
- Residential Retaining Walls: Garden terraces, erosion control, and landscaping
- River and Canal Banks: Channel stabilization and bank protection
- Slope Stabilization: Hillside erosion control and landslide prevention
- Bridge Abutments: Foundation protection and scour prevention

Installation Guidelines
1. Prepare foundation: level and compact soil base
2. Assemble gabion baskets and position correctly
3. Install geotextile fabric behind baskets if required
4. Fill with appropriate stonefill material
5. Secure lids with helical binders or C-rings
6. Stack additional courses if needed, wiring baskets together
