ABSTRACT
A wide variety of construction systems to execute reinforced ground structures exist. Reinforced soil structures consist of improving the properties of the soil by installing reinforcement with metal strips or synthetic mesh, with the aim of providing tensile strength. The implementation of geogrids in the market is a competitive alternative with the added value of environmental sustainability. The geogrids work as a reinforcement element for each layer, distributing the efforts and generating friction due to the soil-reinforcement interaction, in such a way that the friction angle of the ground increases. Consequently, it is possible to use as structural material, tolerable soils with low mechanical properties, thus avoiding the transport of material and making its use viable. In 1979, the first officially executed structure with the combination of gabions and mechanically reinforced soil was built. At the time, a 14-meter structure was verticalized and as these results were extremely satisfactory, the solution was used again in other applications. From this work, the evaluation studies of the use of the double torsion hexagonal mesh as a reinforcement element in private and international laboratories resulted in the creation of the Terramesh System. This type of structure replaces the classic concrete structures which reduces the environmental impact. The mechanical and environmental characteristics are certified in accordance with international institutions and standards that include the CE mark. In this presentation, we want to demonstrate the main criteria, advantages, and durability of the Terramesh systems that have been studied in recent years.
