Large gabion baskets are a hexagonal box structure made of highly corrosion-resistant, high-strength metal wire through a mechanical weaving process. Their height is usually not less than 0.5 meters, and they are larger than ordinary gabion boxes in length, width and other dimensions to meet the needs of large-scale projects.

Performance Advantages
2,000+ Hour Salt Spray Performance
Featuring heavy-duty hot-dip galvanization or deep-coated PVC/PE armor, our gabions are built to withstand the harshest coastal salt fog, high humidity, and acidic/alkaline soils without premature oxidation.
Self-Draining Permeability
The stone-filled matrix creates a 20%–30% natural open area, instantly relieving back-structure hydrostatic pressure to maintain soil-water equilibrium while securing fine particles against erosive piping.
Engineered Seismic Toughness
Woven strictly to ASTM standards, the flexible double-twist mesh comfortably absorbs ±5% ground settlement or frost heave, offering a high-ductility, shatter-proof alternative to rigid concrete in dynamic load zones.
Zero-Maintenance Eco-Restoration
Rock pockets naturally trap silt to trigger spontaneous native plant growth within 3–6 months, eliminating the need for artificial greening and blending the engineered barrier seamlessly into the local ecosystem.
Applications
Large-scale hydraulic revetment: River embankments, reservoir banks, intake diversion walls.
Port and wharf slope protection: Breakwaters, rear slopes of container terminals.
High bridge abutment slopes: Highway bridge cone slopes, railway bridge abutments.
Geological disaster control: Landslide toe ballast, large-scale rockfall retaining walls.
Installation Points
Foundation Treatment
The foundation bearing capacity must be ≥150kPa. A 200-300mm thick crushed stone cushion layer should be laid, and a horizontal geogrid should be installed to enhance anti-slip properties.
01
Assembly and Connection
Large Gabion Baskets require crane assistance for deployment. The spacing between adjacent gabions should be ≤100mm, and the bottom should be anchored to the foundation.
02
Infilling Process
Layered filling should be used, with each layer compacted using a small vibratory plate to prevent subsidence due to settlement.
03
Backfilling Behind the Gabion Baskets
Backfilling behind the gabions must be synchronized with the gabion filling process. Each layer of soil should be filled before adding another gabion; high-volume filling at once is strictly prohibited.
04
Corner Treatment
Custom-made fan-shaped mesh should be used for corners or curved sections to avoid forced bending on-site, which could deform the mesh.

FAQ
Q: What is the cost difference between large-size gabion baskets and conventional gabion baskets?
A: Large-size gabion baskets integrate reinforcing wires, high-strength edge wires, and a double-diaphragm design. Due to the structural reinforcement, their pure material cost increases by 20%-30% compared to conventional baskets. However, this structure significantly reduces on-site assembly labor and machinery shifts. Based on life-cycle cost calculations, its overall project cost is still superior to that of a rigid concrete retaining wall of the same size.
Q: What is the maximum design height of this large-size gabion basket support structure?
A: Based on Mechanically Stabilized Soil (MSE) engineering theory, large gabion baskets, combined with extended reinforcing mesh, can construct gravity/reinforced composite retaining walls up to 15-20 meters high. Such high slope projects require strict adherence to layered reverse filtration design, geogrid pull-out calculations, and overall sliding stability calculations.
Q: How should the logistics and container capacity of large-size gabion baskets be planned?
A: Our factory uses heavy-duty packing machines to fold and compress large-sized containers (each bundle is approximately 0.3-0.5m thick after compression), and then secures them with construction-grade steel straps. The standard loading capacity for a 20-foot standard container is approximately 600-800 square meters (based on the total unfolded area of the mesh panels). We will provide customized packing and loading solutions for specific orders to optimize the utilization of internal space.
