Our eco-friendly walls are examples of the technically called "reinforced ground walls". They consist of the development of earth walls that have been reinforced. Their angle of internal friction varies and this way we achieve much wider angles in the outer sides.
The reinforcement of this earth is carried out through the insertion of different quality materials in it. These so-called materials give the structure a big resistance against slides and/or undesired turn overs and make it stay up strong, thus becoming one of the best ground structures that can nowadays be found.
