Gabions

‘Functional, sustainable and environmentally friendly’:

Those are the characteristics of Gabions. Gabions are boxes made of twisted or welded steel wire. These boxes, filled with rock, present a flexible, multi-purpose building block for civil constructions such as scour protection, retaining walls, erosion control structures, sound barriers, bridge heads or plain decorative landscape elements.

Since the invention and first commercial applications of gabions and gabion mattresses more than 110 years ago, millions of square and cubic meters of gabions have been installed succesfully all over the world.

The main advantages of gabions in a nutshell: stable yet flexible and water transparent building material, cost effective (they can be filled with recycled material or rubble), easy to install (low-tech and labour intensive) by local work force, environmentally sound in terms of material and energy input compared to conventional solutions; can be applied in dry or wet conditions.

Nautilus Eco-Solutions bv can supply all current sizes and shapes of gabions, twisted as well as welded mesh gabions, zinc-galvanised, aluminum-zinc galvanised or zinc-galvanised and plastified. We also try to meet any special requirements.

Applications

Gabions: these multi-purpose building blocks can be used for a variety of purposes: bank and slope protection, noise barriers, bridge heads or plain decorative landscape elements and even for offshore scour protection.

The type of gabion material to be used depends on the required properties of the application: While “twisted” mesh gabions are most commonly used for bank and slope protection, noise barriers, visible walls and landscape elements are mostly built in welded mesh gabions.

The following applications for gabions are typical examples, but give only a limited overview of the broad range of possible applications. From garden walls, lightweight foundations all the way to floating elements: there are countless options also for the filling material.

Gabions in sound barriers and walls

For large scale applications and for cases where aesthetics play an important role, as in the case of this sound barrier, clients typically choose welded mesh gabions. Because of their massive yet porous structure, gabion walls absorb noise very effectively and offer possibilities for the development of plant life such as ivy or stonecrop species.

Similar gabion walls serve as partition structure, garden walls and landscape element. Design, size and filling material are variable.

Gabions in facades and cladding

In recent times, architects of residential and urban constructions make increasing use of gabions as a way of cladding facades. Because they are not carried by their own weight, narrow and high gabion walls have to be anchored in the wall or be built around a special steel frame. Besides the esthetical values, isolating properties and small scale natural habitat function are assets of gabion facades.

Architects enjoy the rocky, somewhat homespun surface which give gabion facades an ideosyncratic character. Even the Irish pavillion on the World Expo in Hannover was built in gabions to reflect the countries untamed, coarse highland landscape.

Gabions in cladding are usually applied nearby high- and waterways. They are anchored the same way as facades. Main reason for the use of gabions in facades and cladding is ofcourse, the aesthetics. It can truely be a piece of art. It’s a fantastic way for an architect to make name for himself. Click here for more information on gabion facades and cladding.

Gabions in shores and earth retaining walls

Erosion control in rivers and canalized waterways is the original and still the most popular application of gabions and gabion mattresses. Gabions are heavy, massive yet flexible, adaptable and water-permeable, thus forming a lasting embankment which does not cause hydrostatic pressures and which does not hinder nature development.

Gabions as a “heavy weight construction” can also serve as retaining walls, dam linings, stabilise slopes, protect dykes, bridge a height differential and the like in the dry.

For constructive stability, a stepwise, gradual design is advised. By prolonging the mesh wire of the lidpanels and anchoring them into the soil behind, a reinforced earth-type construction can be achieved: a stable and efficient way of retaining banks, slopes and steep hills.

From an ecological point of view, for instance for environmental compensation, combining gabions with Aqua-Flora® products provide almost instant and beautiful results.

Ecological and environmental aspects

Gabions are a resource efficient and environmentally sound building material in comparison to, for instance, metal sheet piling or concrete walls. All components are entirely recyclable. Recycled rubble is a common filling material. Energy input is low compared to alternative materials and seen over the long lifecycle.

Furthermore, gabions and gabion mattresses in particular easily blend in with the natural surroundings. Local fauna and flora will develop on and through the porous structure of the gabions.

Sound barriers built in gabions absorb noise and can become a “green wall”: A small “rocky” habitat for specialized flora and fauna. By combining functions (here: constructive and ecological) urban and city planners can make efficient use of a scarce resource: space.

In banks and shorelines, gabion mattrasses constitute a shallow, smooth transitionzone which is a characteristic feature of an ecological embankment. If need be, the gabions can be combined with Aqua-Flora® mats in order to provide instant vegetation.

Characteristics of gabions

Gabions or gabion mattresses are flexible mesh wire boxes filled with stone, soil and/or other materials. Gabions are usually fabricated per project according to the wishes and preferences of our customer. There are however some commonly used sizes.

Welded gabions

Welded gabions have a rectangular or square mesh opening and are manufactured from ‘galfan’ wire (wire with a beforehand applied alloy, consisting of 95% zinc (Zn) and 5% aluminum (Al)). The subsurface for applying gabions is, in most cases, sufficient bearing strength for a foundation on steel in which case, a work floor of concrete or a layer of debris is sufficient.

There are endless possibilities when it comes to choosing a filling for the gabions. Broken stone, rubble, bricks or other materials can all be used, the filling does have to be frost proof. Gabions filled with soil is also possible, this requires an additional layer of geotextile lining or coconut fiber on the inside.

Commonly used mesh widths on welded gabions;

50x50mm
75x75mm
100x100mm
50x100mm.

Commonly used wire diameter on welded gabions;

4.0mm
4.5mm
5.0mm.

Welded gabions

Welded gabions are available in the following sizes;

Mesh width Wire diameter Binding wire
60 x 80mm 2,0; 2,2; 2,7mm 2,4; 2,7mm
80 x 100mm 2,5; 2,7; 3,0mm 2,4; 3,8mm
100 x 120mm 2,7; 3,0mm 2,4; 3,8mm
Gabion mattrasses for purposes of erosion control are availble in the following sizes: We can offer these in thicknesses of 17, 23 en 30cm and sizes of 2 x 2m, 2 x 3m t/m 2 x 6m.

For the complete specifications of gabions (welded and twisted) and gabion matresses please contact us. For the bigger projects and projects where aesthetics play an important role, welded gabions are mostly chosen.
