The purpose of geo-textiles in the reinforcement function is to reinforce the weak sub-grade or subsoil. It helps to strengthen the soil surface and to increase the soils ability to stay put especially on the slopes. Due to this the slopes are stabilised either permanently or temporarily and creep stops or at least diminishes. Further, it helps in preventing water from permeating a slope and controlling the amount of infiltration that occurs during various rain events. Reinforcing aspect of geo-textiles can be used for roads, temporary roads, pavements, airstrips, stabilised road slopes, retaining walls, containment systems, controlling reflective cracking, fibre or fabric reinforced concrete etc. Asphalt impregnated geo-textile is used as a paving fabric, relieving stress and acting as a moisture barrier. For reinforcement, synthetic woven fabric or spun-bond is preferred. Reinforcement is further enhanced by the use of geo-grids or geo-nets.
