Gabion Retaining Wall | PVC Coated Gabion Baskets for Slope Protection

Product Overview

Our PVC Coated Gabion Baskets are double-twisted hexagonal wire mesh containers engineered specifically for heavy-duty earth retention, slope stabilization, and erosion control. Manufactured in strict compliance with ASTM A975 (Style 3), each unit features a heavily zinc-coated or Galfan (Zn-5% Al-MM) steel wire core extruded with an organic polymer PVC protective coating.

The double-twist woven construction ensures continuous structural integrity without unraveling even under localized stone shifting, differential ground settlement, or extreme hydrodynamic shear forces. These baskets are supplied flat-packed, folded into position on-site, and filled with natural stone to create monolithic, free-draining gravity structures.

Key Advantages

• Dual-Layer Anti-Corrosion Barrier: Combining hot-dip galvanization or Galfan alloy with an impermeable, UV-resistant PVC outer layer shields the core wire from aggressive chemicals, marine salinity, acidic soils, and standing water.

• Flexible Gravity Structure: Unlike rigid concrete walls that crack and fail during ground displacement, double-twisted gabions naturally deform and adjust to subgrade settlement without loss of structural capacity.

• Natural Drainage & Hydraulic Relief: Stone matrix provides high natural permeability, dissipating hydrostatic pressure behind the wall automatically. Eliminates the need for complex, costly artificial sub-drainage systems.

• Ecological Integration: Gaps between rock fill naturally collect sediment over time, supporting root growth and vegetative cover to blend into the surrounding landscape.

• Rapid Jobsite Deployment: Delivered folded flat for efficient container shipping; erected quickly using pneumatic lacing tools or manual tie wire without requiring specialized heavy machinery.

Applications

• Slope Stabilization & Landslide Mitigation: Reinforcing highway embankments, railway cuttings, and steep hillsides subject to slippage.

• Retaining Wall Construction: Tiered or vertical gravity retaining walls for commercial sites, highway expansion, and residential grade changes.

• Riverbank & Channel Lining: Scour protection, stormwater canal armor, and stream bank training under high flow velocities.

• Coastal & Marine Infrastructure: Seawalls, breakwaters, groin structures, and tidal zone revetments exposed to aggressive saltwater environments.

• Culvert Headwalls & Bridge Abutments: Scour aprons, culvert wing walls, and bridge pier protection against hydraulic erosion.

•
