Gabions are wire mesh gauge formed by connecting individual wire mesh panels with helical spirals on the vertical edge wires creating an open series of box compartments that are folded into a concertina wire.
Gabions are engineered in the form of retaining structures designed as mass gravity walls to hold back earth or other solid materials without the risk of overturning, sliding, or foundation failure. Gabion retaining wall should be checked by a well-qualified structural engineer on site before construction.
The gabion structure helps variation in the section to be accommodated according to the increase in height. The strength of theses units ensures dimensional and structural stability while a degree of flexibility accommodates ground movement and settlement when necessary.
Trapions are a form of gabion structure created from welded wire mesh panels with either one or both the faces inclined at varying angles to the horizontal dependent. They are supplied in lengths of 1, 2 or 3m or part lengths and pre-assembled with helical spirals for flat packing and ease of transportation.
This inclination of the walls is tilted around 8% degrees from the vertical which is essential for the stability of these structures. The gabion wall specification ends are terminated with prefabricated weldmesh panels. Trapions are normally filled with gabion stone for a rusty appearance.
