Who invented gabions?

Gaetano Maccaferri
The most common civil engineering use of gabions was refined and patented by Gaetano Maccaferri in the late 1800s in Sacerno, Emilia Romagna and used to stabilise shorelines, stream banks or slopes against erosion.

What is the purpose of gabions?

The primary purpose of gabion retaining wall is to provide lateral movement of soil or rock in order to control the active earth pressure and also resist the transverse load in case of gravity retaining wall which are settled and stabilized by their weight.

How long do gabions last for?

50 to 100 years
A gabion wall’s lifespan depends on the type of wire used and the amount of salt spray it is exposed to. “Something that is very coastal tends to rust out like any metal a little quicker,” Jurgensen says. “The further inland you go the longer these tend to last but 50 to 100 years is the typical lifespan.”

Are gabion walls structural?

A gabion wall is a retaining wall made of stacked stone-filled gabions tied together with wire. Gabion walls are usually battered (angled back towards the slope), or stepped back with the slope, rather than stacked vertically. Some gabion manufacturers guarantee a structural consistency of 50 years.

Do gabions need foundations?

Gabion structures, whether walls or fences, do not need a concrete foundation. However, they do need some work under the surface. Otherwise, as heavy as they are, they would be easy to topple over. Unlike many other walls, Gabion does not require a concrete foundation.

How do I stop my gabions from bulging?

Filling – use our guide to filling gabions. Use windlass braces to ensure gabions do not bulge. Use corner braces if required. Ensure that the gabion wall design is based on factual soil investigations.

How high can a gabion wall be?

10.0m high
For inexperienced installers we recommend adding a 4mm face for walls 3m and below, this reduces the risk of bulging. The selection of wire diameter is not straight forward. Below photos include examples of gabion retaining walls up to 10.0m high and constructed using various wire diameters.
