Reinforced Soil Walls and Slopes

When it comes to using reinforcements to grant better mechanical performance to soils, geosynthetics, one of the newest groups of building materials, have become mandatory in almost all works of infrastructure, draining applications, waterproofing, paving, erosion control and soil reinforcement.
