High-Performance PVC Coated Hexagonal Woven Gabion Baskets for Retaining Wall Construction

1. Product Overview

PVC Coated Hexagonal Woven Gabion Baskets represent an engineered, durable, and cost-effective solution specifically designed for heavy-duty earth retention, soil erosion control, and slope stabilization. Fabricated from high-tensile steel wire with a heavy galvanized undercoat and an extruded Polyvinyl Chloride (PVC) protective layer, these gabion baskets are mechanically woven into a continuous double-twisted hexagonal mesh structure.

Engineered specifically for gravity retaining walls, riverbank protection, and coastal defense, the double-twist woven design ensures structural flexibility and non-raveling integrity, allowing the structure to absorb differential settlement without mechanical failure.

2. Structural & Material Engineering Details

• Double-Twist Hexagonal Woven Pattern: Manufactured via continuous mechanical weaving, the hexagonal mesh features a double-twist lock mechanism. This prevents catastrophic unraveling in the event of accidental wire cut or rupture, maintaining tension and structural stability across the entire matrix.

• Dual Anti-Corrosion Barrier:

  • Primary Layer: High-purity zinc or Galfan (95% Zn / 5% Al-Mischmetal) galvanization, offering exceptional sacrificial corrosion protection.

  • Secondary Layer: Heavy-duty, UV-stabilized PVC coating. The polymer jacket isolates the metal core from severe environmental exposures, including saltwater immersion, acidic soils, industrial effluents, and prolonged UV light.

• Internal Diaphragm Reinforcement: To preserve structural geometry during filling and compaction, gabion baskets are partitioned into uniform internal cells using internal wire diaphragms spaced at 1-meter intervals along the length.

• Heavy-Gauge Selvedge Wires: All perimeter edges are reinforced with larger-diameter selvedge wires, ensuring stress distribution during installation and tensioning.

3. Key Advantages for Retaining Wall Applications

• High Permeability & Self-Draining Design: The rock-filled basket structure allows natural groundwater drainage through the void spaces, automatically eliminating hydrostatic pressure buildup behind the retaining wall—a primary cause of conventional masonry wall failures.

• Flexible Structural Integrity: Unlike rigid concrete structures, woven gabions can articulate and conform to ongoing soil movement and ground settlement without cracking or structural collapse.

• Eco-Friendly & Bio-Engineered Integration: Over time, silt fills the voids between the stone infill, promoting vegetation growth and natural root anchoring. This enhances the wall’s structural binding while blending seamlessly into the surrounding landscape.

• Exceptional Longevity: Designed for demanding civil engineering environments, the combination of Galfan/zinc substrate and UV-resistant PVC coating yields a service life exceeding 50 to 70 years under harsh environmental conditions.

• Cost-Efficient Installation: Requires low-skilled labor for assembly and placement. Baskets ship flat-packed to minimize transport volumes and are easily expanded and filled on-site with locally sourced stone or quarry rocks.
