What is Gabion?

Gabion are rectangular welded wire cage or box which are filled with materials such as stone, concrete, sand, or soil. So, these are used as  flexible block construction for slope stability and erosion protection in construction. 

Different types of gabions are constructed and used in  constructions. Gabions are a porous type of structure and sometimes these can be vegetated which improves durability and stability.  

Types of Gabions

1.  Gabion Baskets

2. Gabion Mattresses

3. Gabion Sacks

4. Gabion Wire Mesh

5. Decorative Gabion Elements

1. Gabion Basket

Gabion Basket

These are box shaped net wire mesh with which comes in different sizes. gabion basket are usually used in highway and railway works. and can be economical only when the filling material is available near project site.

2. Gabion Mattresses

Gabion Mattresses

Gabion mattresses are shorter than the other types of gabions. These are used in channel coating to prevent erosion. The standard size of mattresses would be 6m in length, 2m width and 3m height.

3. Gabion Sacks

Gabion Sacks

Gabion sacks has porous and flexible structure and these are generally used in hydraulic works.

4. Gabion Wire Mesh

Gabion Wire Mesh

Gabion wire mesh are used in-order to prevent the fall of rock and stone on highways and railway surfaces. It enhance the stability of the slope and helps in anti-erosion.
