PVC Coated Gabion Wire Mesh Durable Retaining Wall Basket for Soil Stabilization

• Core Metallurgy: Heavy hot-dipped galvanized wire (Zinc or Zinc-Aluminum Galfan alloy) ensuring premium internal protection.
• Polymer Armor: Tough, extruded Polyvinyl Chloride (PVC) coating, minimum thickness 0.5mm, tightly bonded to eliminate internal air gaps.
• UV & Chemical Stability: PVC compound is UV-stabilized and resistant to sea salts, organic acids, and industrial chemical runoff (compliant with ASTM A975 / EN 10223-3).
• Weave Security: Double-twisted hexagonal pattern ensures that if any single wire is mechanically severed by rocky backfill, the overall tensile strength of the retaining wall remains uncompromised.

Proven Soil Stabilization Project Briefs

Our PVC coated retaining wall baskets are widely specified in international public works where soil conditions are unstable and highly corrosive:

• The Challenge: A newly cut mountain highway slope was highly prone to landslides. The local soil possessed a low pH (high acidity) and high moisture retention, which would quickly corrode standard metal mesh.
• The Solution: A stepped gabion retaining wall constructed with our PVC Coated Gabion Baskets, backfilled with graded granite.
• The Outcome: The PVC coating completely isolated the steel core from the acidic soil chemistry. Even with continuous groundwater seepage through the retaining wall, the structure has shown zero rust or deformation over 7 years of monitoring.

• The Challenge: Tidal fluctuations and saltwater spray were causing severe subgrade erosion underneath a vital coastal tourist road.
• The Solution: A massive sea-front gabion revetment wall utilizing PVC-coated stone cages to absorb wave energy and retain the road foundation.
• The Outcome: The dual-layer coating successfully resisted the brutal abrasive action of shifting beach gravel and saltwater corrosion, saving the city millions in emergency roadway reconstruction.

• Elimination of Hydrostatic Failure (Self-Draining Wall): Traditional concrete or shotcrete retaining walls often fail due to water buildup behind the structure. Our PVC gabion walls feature over 30% natural porosity. Groundwater drains freely, removing the hydrostatic pressure that triggers slope failures.
• Unyielding UV Resistance in Arid Regions: Exposed retaining walls face intense, direct sunlight. Our proprietary PVC compound includes advanced UV inhibitors that prevent the polymer from cracking, scaling, or becoming brittle under extreme solar radiation.
• Flexible Response to Severe Differential Settlement: Unlike rigid concrete structures that crack and fail when the underlying soil shifts, our double-twisted mesh accommodates minor subgrade settlements dynamically. The wall moves with the earth, maintaining structural continuity.
• Decades of Maintenance-Free Operation (Lowest Life-Cycle Cost): While the initial material cost of PVC-coated wire is slightly higher than basic galvanized wire, it extends the structure's service life by 20 to 30 years in harsh environments, completely eliminating the need for costly structural repairs or replacements.
• Green Infrastructure Integration: As soil particles deposit within the stone voids, native vegetation roots spontaneously within the wall. This biotechnical stabilization locks the gabion structure into the landscape, transforming a grey engineering asset into a green, living retaining wall.
