High-Strength PVC Gabion Stone Retaining Wall System For Tidal Barrage Reinforcement And Estuarine Flood Control Projects

High-Strength PVC Gabion Stone Retaining Wall System For Tidal Barrage Reinforcement And Estuarine Flood Control Projects

Constructed with double-twisted hexagonal steel mesh (3.2-4.0mm wire) and ISO 1461-compliant galvanization (≥275g/m²), our gabion walls are engineered for tidal barrage reinforcement and estuarine flood control. The 70×90mm mesh configuration integrates with anti-salinity geocomposites to stabilize brackish water zones and lockgate peripheries. Designed for curved installations in harbor basins and saltmarsh restoration projects, the system supports hybrid stone-concrete fills (200-400mm) for wave energy dissipation. Customizable in segmented modules (1-4m height) with sacrificial anode compatibility for extended service life in aggressive coastal environments.

1. Superior Corrosion & Salt-Water Resistance – The extra PVC skin shields the zinc layer from aggressive coastal or acid soils, doubling the service life compared with plain galvanized baskets.
2. High UV & Ozone Stability – Special UV inhibitors in the PVC blend prevent cracking or chalking under intense tropical sun, keeping the coating flexible for decades.
3. Extra Abrasion Defense – The 0.5–1.0 mm thick polymer sheath acts as a “cushion” against stone rubbing, wave-borne sand or floating debris, so the underlying wire retains its tensile strength.
4. Quiet, Low-Maintenance Solution – No rust stains, no annual painting; once filled, the structure needs only visual inspections, cutting life-cycle costs for remote Philippine or Latin-American sites.
5. Green Aesthetic Option – PVC is supplied in earth-tone or vegetation-green colors that blend with natural slopes and can even be co-extruded with a matte finish to mimic rock.
6. Faster, Safer Installation – Uniform 6×8 cm or 8×10 cm mesh plus pre-attached diaphragms let local crews assemble 30 % quicker than concrete walls, reducing labor budgets and on-site risks.
7. Flexible yet Strong – The double-twist hexagonal weave allows controlled settlement without structural failure, ideal for seismic zones or soft riverbank soils.
8. Permeable & Eco-Friendly – Open stone fill drains freely, eliminating hydro-static pressure and letting plants colonize the face, turning the wall into a living retaining system.

Product Introduction:
Gabion retaining walls are flexible, wire-mesh structures filled with rocks, stones, or other materials. These retaining walls are designed to control soil erosion, prevent landslides, and manage water flow. They consist of wire mesh cages filled with stones to form a sturdy natural barrier that can withstand soil pressure and water impact.

Product Specifications:
Mesh Size: 3" x 3" (square opening) or 60x80mm, 80x100mm,100x120mm,

Dimensions:
Length: Customized according to project requirements.
Width: Customized according to project requirements.
Height: Customized according to project requirements.
Wire Diameter: 3mm, 4mm, 5mm.
Surface Treatment: Galvanizing, PVC coating.

Product Advantages:
Durability: Gabion retaining walls have a long service life and can withstand harsh environmental conditions. The wire mesh is usually galvanized or PVC-coated to prevent corrosion, ensuring the wall structure remains stable for many years.
Flexibility: Unlike rigid retaining walls, gabion retaining walls are flexible and can adapt to ground movement without cracking or failing. This makes them ideal for areas prone to soil erosion or seismic activity.
Permeability: The porous nature of gabion retaining walls allows water to pass through, reducing water pressure behind the wall and preventing water-related damage.
Environmental Friendliness: Gabion retaining walls use natural materials and can seamlessly blend with the environment. They can be constructed with locally sourced stones to minimize environmental impact.
Cost-effectiveness: Gabion retaining walls are relatively inexpensive to build and maintain. The materials are affordable, and the construction process is simple, requiring less labor and equipment.
Aesthetic Appeal: Gabion retaining walls have a natural, rustic appearance that can enhance the visual appeal of any landscape. They can be customized with different types and colors of stones to match the surrounding environment.

Application Fields:
Water Conservancy Projects: Used for embankments, riverbank protection, and waterway lining to effectively prevent scouring by water flow.
Environmental Protection: Play an important role in ecological restoration and soil conservation.
Road Protection: Protect road foundations, enhancing the stability and durability of roads.
Coastal Protection: Used in seawalls and port projects to resist wave erosion.
Architectural Decoration: Used as decorative elements on building exteriors, providing a unique visual effect.

Recently, Weld Mesh Gabions have been regularly used as architectural retaining walls, as well as architectural cladding for buildings. This is a testament to the quality of finish that is possible with Welded Mesh Gabions when constructed properly.

All our welded mesh gabions are manufactured in China, giving us the flexibility to supply made to order non-standard sizes and configurations with a minimal lead-in time. We can supply almost any specification or combination of specifications of gabions for all applications and durability specifications. Types of mesh in stock are 3mm Galfan, 4mm Galfan, 5mm galfan and 3mm green Organic Polymer coated. One popular configuration is 4mm diameter mesh in the front and 3mm diameter mesh everywhere else for extra vandal resistance on the front exposed face of the gabions.

Gabions can be supplied to anywhere in the country and the world. Our welded mesh gabions are usually supplied flat packed for ease of transportation. Our Gabions can also be pre-filled, but only when absolutely necessary because of high transportation and installation costs, as well as compromising the ability of the wall to redistribute loads because adjoining gabions are not interconnected as well.
