Soil erosion is a very serious issue that affects not only the agricultural activities but also the ecology of the region. But, till recently no tangible solutions could be found to arrest the soil erosion. However, now the popular gabion retaining walls have come as a very effective solution which effectively addresses the problem of soil erosion. As a matter of fact, recently a popular garden designer in Australia has used the Gabion principle not only to create level garden areas but also to provide drainage to supply water to the plants.
Yet another architect, while building a meditation platform, has constructed a gabion cage made of volcanic rock. This rock which is made of rocks of thermal mass dispels the heat from the sun. As a result, the rock helps to keep the environment inside the structure cool. Further, the volcanic rock also gives a unique appearance to the building which in fact replicates the appearance of a retreat. All these varied applications underline the extended utilities of the Gabion procedure.
Varieties of Gabions:
As a matter of fact, a gabion, which is believed to have originated from Italy (gabbione; which means big cage) is in the form of either a box or cage and this box is filled with rocks. Now, even exclusive concrete blocks are used to fill the boxes or Gabion. In fact, in some places even locally available hard rocks are used to fill the gabion blocks. In fact, now even heavy concrete blocks varying from 1 to 4 tonnes are used for the construction of these unique gabion walls. With the advancement in construction technology, now, technologists have introduced varieties of gabions. Some of the popular varieties are gabion wire, box gabion, sack gabion and Green matter mesh gabion. Further, gabion wire is an exclusively designed wire with predetermined strength and elongation capability. Normally, the gabion wire will have a zinc coating to ensure the durability of the wire.
Application of Gabions:
Now, gabion retaining walls are extensively built on the slopes of hills and mountains as well as on the embankments of rivers. These are also built for purposes of protecting river channels. Depending on the severity of soil erosion, the gabions are also built in a box design by adopting a heavy hexagonal heating procedure. In order to preserve ecology and also to further arrest the soil erosion, the technologists also suggest that plants should be grown on the top of the gabion baskets. Check out Gravity Wall Systems
Gabions on the sea shore:
In the normal course, gabion retaining walls are durable and are most economical too. However, gabions built on the beaches will have a life span of about 5 to 10 years, depending on the intensity of the waves and wind velocity. This is because the gabion may not be able to withstand the pressure of the waves. Further, by design, there is a gap in between two gabions which makes the gabion a porous structure. As a result, heavy waves and high-velocity winds can dislodge the gabion.
Look for professional architects and builders:
Considering the exclusive characteristics of gabion walls, it is always advisable that specialized and professional architects and builders like the http://www.gravitywallsystems.com/ should be approached for such walls. Such architects and engineers make the best use of the available materials and also ensure that the walls constructed are durable and also cost viable.
