The most common application of gabion supporting walls is in road- and railway construction. Besides gabion cages, gabion mats are also used to cover watercourse beds and banks in water construction. The supporting walls may have to endure great load, and this is why it is so important to take static measurement before the construction of gabion supporting wall system higher than one metre. The measurement has to take into consideration the geological conditions under the system and all the load affecting the supporting walls. The use of gabion supporting walls is justified also when there are level differences of several meters, for the reasons of spatial and financial economy. The cages are built upon one and another in several rows, and the bottom rows are usually wider. The gabion supporting walls are usually built in with a 6 to 8° inclination angle.
In contrast to other technological solutions, gabion the system has the following advantages:
- permeable, which helps the decrease of hydrostatical pressure and minimizes the risk of landslides due to the drenching of the soil behind the wall.
- flexible, being able to follow minor ground movements without losing from its function.
- easy to build as it does not require special foundation or the application specific building industry skills.
- aesthetic as it fits the natural environment without additional covering, retaining its uniqueness by using stones of various different colours, for example.
- environmentally friendlier since, thanks to the use of natural stones, it charges the nature with artificial substances to a lesser extent than, for instance, a reinforced concrete structure.
