Gabions serve two distinct functions depending on the context: a flexible structural solution for hydraulic works and retaining walls on difficult ground, or a decorative architectural element with straight lines for modern design. The choice between double-twist hexagonal mesh and welded mesh is not a matter of nuance: one adapts and the other holds a rigid shape. This comparison of the two MOLTEXO gabions helps you decide which one fits your project.
🎯 Choose in 10 seconds
- If you are working on hydraulic works, a retaining wall on soft soil, erosion control or river channelling: go to Hexagonal mesh gabion
- If you are working on an architectural project with a modern aesthetic, urban furniture or a decorative wall: go to Welded gabion
What to consider before choosing
Before buying, evaluate these four criteria. They determine whether the gabion fulfils its structural function or remains a decorative element that fails under real load.
- Type of project: structural or ornamental: double-twist hexagonal mesh gabions are the classic structural solution for hydraulic works and retaining walls that must adapt to ground settlement. Welded gabions have a rigid architectural aesthetic useful for decorative walls, planters and urban furniture.
- Flexibility vs. structural rigidity: double-twist hexagonal mesh absorbs ground movements and progressive settlement without losing integrity — a critical advantage in hydraulic works with dynamic loads. Welded mesh keeps a rigid shape with straight lines — an advantage in modern architecture but a limitation on soils with irregular compaction.
- Exposure to salinity and continuous moisture: both MOLTEXO gabions are galvanized, but the hexagonal one incorporates an additional PVC coating over the hot-dip galvanizing, which provides reinforced protection for Caribbean coastal areas and hydraulic works with continuous water flow. For interior or dry residential architecture, the galvanizing of the welded gabion is sufficient.
- Permeable natural drainage: both gabions allow natural drainage through the stone fill, preventing the build-up of hydrostatic pressure behind the wall. This property is a differentiating advantage over solid concrete walls in areas with high subsoil moisture or heavy rainfall.
Hexagonal mesh box gabion: a flexible structural solution
- Flexible double twist that absorbs ground settlement
- Hot-dip galvanizing + PVC coating against salt
- Permeable natural drainage through the stone fill
- Integration with vegetation and sediment over time
- Deployment without heavy machinery using locally available stone
- Organic aesthetic less defined than the welded one
- Less recommended for modern architectural projects
Box gabion with hot-dip galvanized double-twist hexagonal mesh with PVC coating, dimensions 2 m × 1 m × 1 m. Designed for retaining walls in road works with soft soils and predictable progressive settlement; slope stabilization with risk of sliding, especially in tropical areas with intense seasonal rainfall; river channelling, bank protection and hydraulic works with continuous water flow; rockfall protection barriers, coastal defences and architectural landscaping projects with a natural aesthetic.
Welded box gabion: rigid architectural aesthetic
- Straight lines and rigid geometry, modern aesthetic
- Structural strength through welded design
- Permeable natural drainage like the hexagonal one
- Fill versatility: stone, recycled glass, decorative finishes
- Quick assembly without heavy machinery
- No flexibility for progressive ground settlement
- Galvanizing without PVC coating: less suitable for saline coastal areas
Box gabion with welded steel wire mesh, dimensions 2 m × 1 m × 1 m. Designed for architectural retaining walls in residential and commercial projects and urban infrastructure; decorative planters, landscaping dividers and exterior design elements with a modern aesthetic; urban furniture (benches, tables, dividers) in squares, parks and pedestrian areas; façade cladding and industrial-architectural design elements in bars, restaurants and interior design.

Before buying, define two things: whether the gabion is structural or decorative, and whether it is exposed to coastal salinity or continuous water flow. The practical rule: hydraulic works or retaining wall on difficult ground → double-twist hexagonal with galvanizing + PVC; modern architecture or urban furniture → welded. The flexibility of the hexagonal versus the rigidity of the welded one is the most important difference in real conditions.
Do not use a welded gabion in hydraulic works with continuous flow or in coastal areas with marine salinity. Galvanizing without an additional PVC coating corrodes quickly in these conditions, compromising structural integrity. For hydraulic works, the only correct option is the double-twist hexagonal gabion with dual galvanized + PVC protection.

Frequently asked questions
Which stone do I use to fill the gabions?
Angular quarry stone larger than the mesh opening, so that it is not lost during handling. For hydraulic works, hard non-erodible stone is preferred; for architecture you can use ornamental stone, local natural stone or even recycled glass for decorative finishes in welded gabions.
How long does a hexagonal gabion last in a Caribbean coastal area?
Decades under standard operating conditions thanks to the dual protection of hot-dip galvanizing plus PVC coating. The double twist absorbs ground movements and the galvanizing+PVC combination resists marine salinity and continuous moisture. Without the dual protection, the service life is significantly reduced.
Do gabions look ugly over time?
It depends on the context. Hexagonal gabions blend into the landscape over time as vegetation grows between the stones, an advantage in environmental works and natural landscaping. Welded gabions keep their rigid modern aesthetic for decades — an advantage in architecture where visual permanence is sought.
