Rockfall protection begins with a clear understanding of the hazard. Falling blocks can threaten highways, railways, bridges, tunnels, industrial sites, residential developments, and mountain infrastructure. A suitable protection system must account for the source area, slope geometry, block size, trajectory, impact energy, drainage, access, maintenance, and the consequences of failure.
At Fande, we provide woven gabion mesh products that can support several parts of a rockfall protection strategy. Our double-twisted woven gabion mesh, gabion boxes, Reno mattresses, and corrosion-resistant wire coatings can be used for catch walls, toe protection, slope-surface control, erosion management, drainage-compatible retaining structures, and hybrid protection systems.
Fande woven gabion mesh is manufactured as a double-twisted hexagonal wire mesh system. The double-twisted configuration helps prevent a local break from unravelling across the entire panel. It also provides flexibility that can accommodate limited ground movement more effectively than a rigid panel, provided that the mesh, anchors, connections, and support details are properly designed.
For suitable slopes, woven mesh may be used as part of a draped or anchored mesh arrangement. Depending on the design, the mesh can help retain smaller loose fragments against the slope or guide detached material downward toward a controlled catchment zone. It can also reduce surface ravelling and limit the migration of soil and small debris.
Gabion boxes are wire-mesh cages assembled into box-shaped units and filled with properly graded rock. Their mass, permeability, modular form, and ability to tolerate some differential movement make them useful for retaining and protective works at the toe of a slope.
In a rockfall project, a gabion wall may support a catchment strategy by helping to retain debris at the base of a slope, protect a road shoulder, stabilize a drainage channel, or separate a hazard zone from an occupied area.
The wall’s performance depends on its height, width, foundation, setback, batter, internal cell arrangement, lacing, rock fill, drainage, and connection to the surrounding ground.
Reno mattresses are low-profile, wide units made from double-twisted hexagonal mesh and filled with rock. Their geometry allows them to cover a broad area while remaining relatively thin. They are commonly used for channel linings, embankment protection, slope toes, spillways, and areas exposed to erosion or shallow surface instability.
In rockfall protection projects, Reno mattresses can support the overall system in several ways. They can protect the toe from runoff and scour, reduce erosion that may undermine a catch wall, stabilize shallow soil or weathered rock surfaces, and improve the durability of drainage paths around a protective structure.
This integrated function is important. Rockfall risk is not controlled only by intercepting falling blocks. Persistent runoff, channel erosion, freeze-thaw action, and loss of toe support can create new release surfaces.
• Galvanized woven gabion mesh:For inland projects with moderate corrosion exposure, galvanized wire may be appropriate when the project specification and environmental assessment support that choice.
• Galfan zinc-aluminum alloy mesh:Galfan coatings are often considered for humid, wet, or more aggressive environments because the alloy coating provides a corrosion-resistant metallic protection system while maintaining wire flexibility.
• Polymer-coated gabion mesh:For marine, saline, polluted, acidic, or highly abrasive conditions, a polymer-coated wire configuration may offer an additional protective layer over the metallic coating.
• Flexibility under ground movement:Natural and cut slopes can experience settlement, local erosion, weathering, and small movements. A flexible woven mesh can conform to an irregular surface more readily than a rigid panel.
• Permeability and drainage compatibility:Woven gabion systems and rock-filled gabion structures are generally permeable, allowing water to pass through when they are installed with appropriate filters and drainage details.
• Modular installation and repair:Gabion boxes and Reno mattresses are modular. Contractors can transport, assemble, fill, connect, and repair them in stages, which may be valuable at remote road, railway, mining, hydropower, and mountain sites.
Fande supports rockfall protection projects with woven gabion mesh, gabion boxes, Reno mattresses, galvanized wire, Galfan-coated wire, and polymer-coated configurations. These products can contribute to slope-surface control, erosion reduction, toe protection, drainage-compatible construction, catch-wall systems, and hybrid rockfall mitigation designs.

What is the difference between a gabion wall and a rockfall fence?
A gabion wall is a gravity-type, rock-filled modular structure that can provide mass, retention, toe protection, and separation. A rockfall fence is typically a flexible interception system designed around defined impact energy, height, deflection, anchors, and posts. They are not interchangeable. A gabion wall may form part of a catchment strategy, while a certified fence is designed to intercept falling blocks at a specified performance level.
When should I choose a Reno mattress for a rockfall project?
Choose a Reno mattress when erosion, scour, shallow surface instability, drainage, or toe protection is part of the project problem. Reno mattresses are especially useful where a low-profile, permeable, rock-filled lining is needed. They do not replace a rockfall barrier when the primary hazard is a high-energy falling block.
Which coating should I choose for a coastal or polluted site?
The correct choice depends on the exposure assessment and project specification. Galfan may be appropriate for many wet or humid environments, while polymer-coated wire can provide an additional protective layer in more aggressive or abrasive conditions. Coastal, industrial, acidic, and saline sites require a documented coating specification and careful protection of cut ends, connections, and damaged areas.
