Gabion Baskets - Galfan Gabion Baskets, Double Wire Woven Mesh Gabion Baskets, Mattresses

Gabion baskets are rectangular mesh containers crafted from mild tensile steel wire, with diameters ranging from 2mm to 8mm. These can be welded or woven, galvanized, Galfan, or plastic-coated. Filled with suitably sized rocks or quarry stones, they are pivotal in retaining wall construction due to their flexibility, durability, strength, permeability, economy, and aesthetic appeal. The hexagonal double-twist wire mesh basket gabions are generally class A galvanized to SABS 675 of 1993. Internal cells are created by adding diaphragms, which are mesh panels with similar characteristics to the external sides, spaced 1m apart to reinforce the structure and expedite construction.

Gabion baskets, available in welded mesh or woven wire, are extensively used in different scenarios including earth movement and erosion stabilization, river control, reservoirs, canal refurbishment, landscaping, and retaining walls.

Gabion Baskets of Galvanized Steel Hexagonal Wire Mesh

These basket-shaped compartmentalized containers are made of galvanized steel hexagonal wire mesh. Their robust construction is capable of holding the stone fills needed for channel and foundation shifts.

The galvanized wire can be coated with a 0.5mm thick PVC (polyvinyl chloride) layer before weaving to ensure complete protection from corrosion in marine or polluted environments.

Must-Have Features

This type of gabion basket must have the following features to meet various needs:

• Hexagonal mesh pattern critical points
• Double twist to avoid unraveling
• Reinforcing wires woven into corners
• A securely attached diaphragm at the base to prevent shifting and reinforce the gabion

Advantages

1. Flexible: Adaptable to varying conditions of earth settlement without causing fractures.
2. Durable: Gaps between stones fill naturally over time, supporting vegetation growth.
3. Permeable: Allows water to pass through, preventing build-up of water pressure.
4. Strong: Flexibility enables it to withstand pressures from water and earth masses.
5. Economical: Filling materials are usually locally sourced, eliminating the need for structural maintenance.
6. Natural Appearance: Natural stone makes the structure aesthetically pleasing, enhancing with vegetation coverage.
7. Simple: Easy assembly requiring unskilled labor.
8. Maintenance: Easily maintained using additional mesh or grout.
9. Functional: Becomes immediately functional once constructed.
10. Extendable: Simple attachment of additional units to existing ones.

Baskets come in a flat pack form and are assembled on-site, usable for a range of applications from small domestic projects to large industrial schemes. Typically, locally sourced stones ranging from 200mm to 100mm are used as infill. Hand facing ensues a good cosmetic appearance.

Projects

Heavy Galvanized Mattress Basket of Gabions Work

Resistance: Heavily galvanized with Galfan, a Zn-5% Al-MM (mischmetal) alloy, followed by a 0.5 mm thick PVC/Epoxy coating. Gabion sizes: 2x1x0.3m and 2x1x0.5m.

Materials: The quality of stones and wire used in gabion manufacture is high, meeting standards like EN 10223-3: Material for mesh, quality of stones, and a heavily galvanized coating with 200 gms per square meter zinc minimum.

Galfan Coated Gabion Baskets and Mattresses

Wire thickness: 5mm for the JAMAICA project. Basket: 1800mm length x 900mm width x 1000mm in height, formed using 8x10 double twisted hexagonal steel woven wire mesh as per ASTM specifications.

Basket Mattress: 3600mm x 2400mm x 150mm with galvanized mattresses held together with 8x10 double-twisted hexagonal steel woven wire mesh, Galfan coated, for a Belgium project using double wire woven mesh gabion baskets and mattresses. Another project in India uses 100mm x 100mm mesh with 10 SWG galvanized iron wire.

Gabion Baskets for Gabion and Pond Works Projects

Lined gabion baskets come in sizes such as 1500 x 1000 x 1000mm and 1000 x 1000 x 1000mm. Standard sizes include 80 x 100 x 2.7mm wire dimensions, with customizable sizes to suit site conditions and Class A galvanized or PVC coating for added protection.

Notes to Design Engineers

Gabions are widely recognized in civil engineering and are specified in most contracts. Their success hinges on proper construction practices, including proper wiring, pretensioning, cross-bracing, and stone filling.

Security

Gabions offer protection against enemy attacks like rocket fire or bomb blasts, providing defense in structures like farmsteads, bunkers, and bomb shelters.

Applications

Basket gabions have numerous applications: mass-gravity walls, reinforced soil walls, river canals, erosion control, architectural cladding, rockfall mesh netting, or even decorative and security structures.
