Maccaferri® gabion basket is a double-twisted "DT" steel wire mesh which is interconnected with similar units to form flexible, permeable and monolithic structures such as mass gravity retaining walls, channel linings, revetments and weirs for hydraulic and erosion control projects.
The gabion baskets are site assembled and packed with locally quarried or imported rock which is carefully hand-placed along all exposed faces of the baskets to ensure the best aesthetic earth retaining structure.
The innovative PoliMac® polymer coating is applied for gabions that are to used in more aggressive environments, or where a longer design life is required to offer greater resistance to abrasion, chemical aggressions, UV rays and performance in cold weather.

WHY CHOOSE MACCAFERRI DT GABION BASKET?
- GalMac & GalMac G10 coatings provide 5x durability compared to standard galvanised mesh
- PoliMac polymer coating provides 10x resistance to abrasion, 2x resistance to chemicals and 4x resistance to UV rays compared to traditional PVC coated wire mesh products
- Enhances biodiversity and vegetation growth by trapping sediment and seed, aiding CO2 sequestration
- Reduces carbon emissions by 10x compared to concrete walls
- Flexible and reliable, accommodating large settlements without structural impact
- Cost-effective alternative to various wall systems such as mass gravity boulder walls, grouted rock walls and mass concrete block walls as it reduces the amount of material needed to build a wall
- Constructible at 5-10 metres height with flexible face options
- Independently verified and tested with BBA-HAPAS certification
- Supported with design assistance using Maccaferri GAWAC 3.0 software available to download here
- Supported with specialist installation tools for hire including pneumatic lacing tools lacing or you can purchase "C" rings and preformed bracing wires to halve assembly time
Our recommended specialist gabion installers can construct sample units on-site before works begin to ensure products are installed as per our guidelines.

FUNCTION
Erosion & Sediment Control
The use of a geosynthetic to prevent soil or other particle movements on the surface slope. Acts to reduce soil erosion caused by wind forces, rainfall impact and surface water runoff. The use of geosynthetics in erosion control is to maintain soil cover either as a temporary measure offering protection from soil loss whilst vegetation is established or as a permanent control measure, typically on steeper slopes or high-water velocity situations.
Reinforcement
Geosynthetics provides additional strength to soils and aggregate. Used to reinforce steep slopes, and to stabilise road or rail construction over weak and variable soils. Enables embankments to be constructed over very soft foundations and to build slopes at steeper angles than would be possible with unreinforced soil. Geosynthetics (or geogrids) are also used to bridge over voids that may develop below load bearing granular layers (roads and railways) or below cover systems in landfill applications.
Retaining
Geosynthetic or geogrid acts to support soil laterally so that the structure can be retained at different levels on the two sides. Retain (holds back) any material (usually earth) and prevents it from sliding or eroding away. Gravity retaining and reinforced soil retaining walls are designed to resist the material pressure of the material that it is holding back.
