PVC Coated Gabion Retaining Wall for Riverbank & Road Slope Protection

1. Product Overview

Our PVC Coated Gabion Baskets are engineered for heavy-duty earth retention, hydraulic training, and slope stabilization projects. Manufactured from high-tensile steel wire with heavy Galfan / Zinc coating and extruded with a resilient polyvinyl chloride (PVC) protective jacket, these double-twisted hexagonal woven wire mesh units provide exceptional structural integrity and long-term durability.

Specifically designed for harsh environments—such as polluted riverbeds, coastal tidal zones, acidic/alkaline soils, and high-salinity highway slopes—the durable PVC polymer sleeve acts as an impervious barrier against chemical corrosion, scouring abrasion, and UV degradation. Once filled on-site with clean, durable stone, these gabions form a flexible, monolithic, and free-draining gravity retaining system that integrates harmoniously with natural ecosystems.

2. Technical Specifications (ASTM Standards Compliant)

All materials, manufacturing tolerances, and mechanical properties strictly conform to ASTM A975 (Standard Specification for Double-Twisted Hexagonal Mesh Gabions and Revet Mattresses) and related American testing standards.

3. Key Product Advantages

• Dual Corrosion & Abrasion Defense

  The fusion of metallic zinc/Galfan substrate protection with an outer high-grade PVC layer ensures maximum resistance to acidic water, chemical runoffs, saline mist, and high-velocity debris abrasion, providing an extended design service life exceeding 50+ years.

• Flexible & Monolithic Structural Response

  The double-twisted weave allows the retaining wall to accommodate differential soil settlement and subgrade deformation without fracturing or losing load-bearing capacity—an essential capability that rigid concrete walls lack.

• Natural Permeability & Hydrostatic Relief

  The porous stone infill allows free water drainage through the wall face, automatically relieving hydrostatic pressure behind the retaining structure. This eliminates the need for complex, costly artificial drainage piping systems.

• Ecological Integration & Bio-Engineering

  Over time, soil and silt naturally deposit in the void spaces between the stone fill, encouraging indigenous vegetation growth and root reinforcement. This blends the retaining structure seamlessly into the surrounding natural landscape.

• Cost-Efficient Installation & Non-Ravelling Security

  Shipped flat-packed to minimize international freight costs, units are simple to assemble and lace on-site using local rock fills. The double-twist design ensures that cutting or breaking an individual wire will not unravel the surrounding mesh.

4. Engineering Applications

• Riverbank Protection & River Training Works

  Erosion mitigation for riverbanks, canal linings, weirs, groynes, drop structures, and flood alleviation channels exposed to high scouring velocities.

• Road & Railway Slope Stabilization

  Gravity and stepped retaining walls along highway cuts, railway embankments, mountain switchbacks, and landslide remediation zones.

• Bridge Abutments & Culvert Wing Walls

  Reinforcing bridge approach embankments and surrounding piers against turbulent water flow and scour.

• Marine & Coastal Defense

  Seawall revetments, tidal channel linings, marina bulkheads, and breakwaters exposed to corrosive saltwater spray.

• Urban Infrastructure & Stormwater Channels

  Detention basin retention walls, drainage ditch protection, and commercial landscape terracing.
