Gabion walls have gained a role in sustainable construction in the rapidly growing infrastructure and landscaping development industry in Saudi Arabia. They are most suitable because of their resilience and versatility whether to be used as highways, flood channels or landscape design of a villa. Of all forms, hexagonal mesh gabion walls with a double-twist are of superior technical specification, product differentiation, and desired structural advantages, especially, settlement and scour resistance.
With cities such as Riyadh, Jeddah and Dammam still committed to modern infrastructure development, the concept of the double twist advantage will be crucial to the contractors, engineers and consultants who appreciate the long term structural integrity in the harsh and dry environment in Saudi Arabia.
Learning about the Double Twist Hexagonal Mesh System
A unique arrangement of wires is the double twist hexagonal mesh in which two strands of wire are twisted together to create a pattern composed of six sides. The design is also unique in that even when one of the strands is cut, the mesh does not unravel which makes it literally safer and more dependable compared to other types of mesh that are welded.
Technical Specification of Double Twist Gabions
These technical specifications are designed to meet the demanding conditions of Saudi projects, from desert drainage channels to mountainous retaining structures.
| Parameter | Specification |
|---|---|
| Mesh Type | Double Twist Hexagonal Mesh |
| Mesh Opening Size | 60 × 80 mm or 80 × 100 mm |
| Wire Diameter | 2.7 mm to 3.9 mm (core), 0.5 mm coating |
| Coating Options | Galvanized, PVC, or Zn-Al alloy (Galfan) |
| Tensile Strength | 350–550 N/mm² |
| Basket Dimensions | 1m × 1m × 1m, 2m × 1m × 0.5m (custom sizes available) |
| Stone Fill Size | 100–200 mm, angular, hard stone like basalt or granite |
Product Differentiation How Hexagonal Mesh Beats Welded Gabions.
Although both welded and hexagonal mesh gabions are applied in retaining as well as erosion control, their product differentiation is in flexibility, strength, and deformation resistance.
Key Differentiators
- Flexibility and Movement Absorption: The double twist structure enables the gabion to flex without failure depending on the settlement of the soil or the changed terrain.
- Corrosion Resistance: Gabion Coatings- Galfan and PVC Coating increase their shelflife even in saline coastal environments such as Jeddah.
- Non-Ravel Design: Contrary to welded mesh, when one of the wires has been damaged, the hexagonal mesh cannot unravel thus ensuring long term safety.
- Convenient to install: The mesh structure can be easily assembled and this saves on time and labor costs incurred by the project.
The hexagonal mesh gabion walls to be used by Hitech are tested in field condition and have been proven to perform better in settlement-prone and high-flow conditions hence they have a clear competitive advantage in product differentiation.
Key structural benefits - Settlement and Scour Resistance.
The most important structural advantages of the double twist gabions are particularly very sensitive to the infrastructure that is exposed to soil movement, water, and erosion. They are also resistant to settlement and scour which is superior thus suitable in the terrain and desert of Saudi Arabia.
Resistance to Settlement
Gabion walls can adapt to the irregular terrain or slight changes in the foundation, which would not result in structural collapse. Their flexibility also spreads loads evenly eliminating stress concentration points. This ensures:
- Stability of walls over an extended period even in case of differential settlement.
- Little maintenance on soft or unstable soils
- Long life span as opposed to concrete structures that are hard to bend.
Resistance to Scour
Scour can be used to take away the base of retaining walls in areas that are likely to experience a high velocity of water or flash flood. This is deterred by hexagonal mesh gabion by
- Hydraulic dissipating permeable structure
- Water-absorbing stones influence the flow in slowness.
- Combination with the use of the gabion mattresses at the base, which ensure the stable foundation with anti-scour properties.
It is this resistance to settling as well as scouring that has led to the use of double twist gabions as the most dependable in managing floods, bridge abutment work and wadi defenses systems in Saudi Arabia.
Technical Performance in Saudi Conditions.
The climate problems facing Saudi Arabia include extreme temperatures, sand erosion and the occasional floods, which require materials that are highly adaptable. Such a technical and environmental stress is covered by hexagonal mesh gabions.
- Temperature Resistance: Coated wires can withstand high temperatures of more than 50 o C without reduction.
- Erosion Controlling: fillings are porous, which means that the pressure remains low and erosion is less likely.
- Performance in Seismic: Due to their flexibility, they are able to absorb energy safely in minor tremors.
- Hydraulic Stability: Will not leak even when the water drops.
The technical requirements assure that the performance of gabions is the same irrespective of the different geographies such as the dry uplands of Riyadh and Dammam coastal areas.
Case Insight: Case of Hitech Gabion in the Eastern Province.
In a protection system to protect a wadi in Dammam, Hitech Gabion has recently installed double twist hexagonal gabions to replace scoured concrete structures by floods.
Results achieved
- Scour resistance 100 percent following two rainy seasons.
- The flexibility of the structure remained in the face of settlement areas.
- 35 percent of the savings of the total project cost through the low maintenance.
The case highlights the direct relationship between technical specification and product differentiation in such a way that they are directly translated into major structural advantages on Saudi projects.
Comparative Overview – Hexagonal vs. Welded Gabions
A technical comparison between hexagonal (double twist) gabions and welded mesh gabions, highlighting structural performance, durability, and application suitability.
| Feature | Hexagonal (Double Twist) | Welded Mesh Gabions |
