Gabions are cages which are engineered from double twisted hexagonal woven steel wire mesh. Delivered flat-packed, gabions are assembled and then filled with stones at the project site.
Gabion baskets are made from high-quality steel wire, which is heavily galvanised. An additional protective polymeric coating is also applied for gabions that are to be used in more aggressive environments, or where a longer design life is required.

- Permeability. Stone filling is characterized by porosity that enables water to flow and doesn’t create hydraulic pressure on the panels of gabion structures, it has drainage function.
- Flexibility and versatility. Gabions are able to deform while still retaining their integrity, they adapt themselves to terrain where the concrete structures may crack and fail, they are suitable for unstable subgrades.
- High resistance and durability. Secured by outstanding features of steel wire, its surface treatment by heavy galvanization or PVC coating and by the quality of stone filling.
- Ecological and aesthetic. Gabion structures during their lifetime merge with surrounding nature, they are grown over by local vegetation, look more aesthetic than concrete structures.
- in Civil Engineering, construction of road and railway embankments, bridges, retaining walls, water dams, channel lining and river training works for following main purposes:
- to stabilize shore or slope against erosion
- to create a barrier that prevents erosion
- to hold back earth or other solid materials without overturning, sliding or foundation failure
- to prevent silt and topsoil from washing away during heavy rains or even floods to reduce water velocities and re-capture bed sediment in streams
- in Military Engineering to protect artillery crews
- Erosion control
