What Problems Occur When Using Gabion Mesh and How to maintain them?

        Woven gabion mesh is widely used in riverbank protection, slope reinforcement, and landscaping projects due to its ease of construction, flexibility, and high permeability. This article provides a set of maintenance and material selection recommendations, focusing on common problems and actionable solutions, to help owners and contractors reduce later operation and maintenance costs and improve project reliability.

        Ⅰ. Frequently Asked Questions and Quick Assessment

        1. Surface rust or pitting: Often caused by insufficient coating, untreated cut edges, or chloride ion corrosion at sea. Diagnosis method: Observe joints, knots, and cut edges for initial rust.

        2. Gabion mesh deformation or collapse: Usually caused by uneven stone loading, oversized filler, or loose cage binding. Structural problems can be determined by inspecting the distance between unit frames and partitions.

        3. Stone leakage or erosion: Often occurs due to insufficient foundation compaction, erosion of the foundation, or improper connections between cages. Checking anchoring and foundation protection is crucial.

        4. Plastic coating peeling or cracking: Often caused by prolonged exposure to UV rays,mechanical friction,or contact with acidic or alkaline media.Materials should be selected according to the environment,and a protective layer should be added.

        Ⅱ. Material selection and process recommendations

        1. Material selection should be based on the engineering environment: for inland freshwater environments, hot-dip galvanized or Galfan steel wire is preferred; for coastal or acidic/alkaline environments, plastic coating before galvanizing or a thicker coating is recommended.

        2. Wire diameter and mesh size should be matched to the design load and stone particle size. The outer frame wire should be one size thicker than the mesh wire to improve impact resistance.

        3. Cutting and twisting joints must be treated with anti-corrosion measures. The double-twisted length should meet the specifications to avoid coating damage.

        Ⅲ. Key Points of Installation and Quality Control

        • The gabion mesh should be placed in layers evenly and compacted appropriately to avoid local voids; the spacing of the partitions, clamping methods, and connectors must strictly adhere to the design specifications.

• Qualified fasteners or hinged devices should be used at joints to avoid premature failure caused by direct welding or temporary binding.
