The development of methods of preparing relatively rigid polymeric materials by tensile drawing, in a sense "cold working," raised the possibility that such materials could be used in the reinforcement of soils for walls, steep slopes, roadway bases and foundation soils. The principal function of geogrids is for reinforcement.
Methods for producing stiff polymers via stretching, or "cold working," led to the idea that these materials could be utilized to strengthen soil in structures like walls, slopes, roadbeds, and foundations. Geogrids are primarily designed for reinforcement purposes.
