In the construction of roads and railways, retaining walls are an essential component to maintain alignment acceptable for moving vehicles and trains. In areas of soft soils roads and railway tracks are prone to local and global subsidence. Retaining walls and constructions over soft soils have been built efficiently and economically in different countries of the world with similar conditions to those found in countries like ours, using appropriately selected and designed geogrids and other geosynthetic products. We are expert in these kinds of applications, from the design to construction.
