Material Specification for Gabions Wall & Stone Pitching

A Gabion structure is prepared from pre-assembled rectangular cages made of double

twisted steel woven wire mesh filled with rocks/ boulders. It is a simple gravity retaining structure, which retains soil with its weight. These types of structures are in use in highways,bridges, canal linings, buildings, shore protection works, etc

The porosity of gabions prevents the pore-water pressure development behind the walls which,is one of the major advantages of these kinds of systems. These structures blend with the surroundings and allow vegetation to take roots through the structure which enhances the life of the structure. Reduced carbon foot prints are also a noticeable feature when compared to conventional solutions.

• Elements of Gabion Wall:

1. Gabion / revet Mattress Mesh (Gabion box)
2. Rocks for filling the Gabion

• Gabion Box:

In my project we have used Zinc metallic coated wire mesh having mesh size of 10x12cm.
