gabion wall vs retaining wall

1) Sustainable – Carbon footprint analyses show that the use of a gabion solution can reduce CO2 emissions by up to 80% compared to a concrete retaining wall of the same height. If allowed to grow, vegetation can establish within a gabion wall, which can further contribute to carbon sequestration of the solution.

Can gabions be used as retaining walls?

Gabion basket retaining walls are a gravity type retaining wall that uses stone filled wire baskets. They are very similar to our concrete block design but can be more economical. The gabion basket allow water to escape if large stone is used to fill the baskets.

What are the disadvantages of gabions?

Disadvantages/Problems

Gabions are sometimes criticized as being unsightly. ...
Low habitat value.
Gabions are more expensive than either vegetated slopes or riprap.
The wire baskets used for gabions may be subject to heavy wear and tear due to wire abrasion by bedload movement in streams with high velocity flow.

Are gabion walls cheaper?

Not only are Gabion walls cheap, but they also last a long time. These two factors combined make them one of the most economical solutions available.

Are gabion walls strong?

Durable. A gabion wall is made of durable wire mesh that makes up the gabion basket and keeps the wall in structure. Another interesting fact is that they even become stronger with time. It`s because of the silt and vegetation being collected in between the filling of the baskets over time.
