Uniaxially stretched geogrid is a kind of high-strength geotextile, which is mainly made of high molecular polymer, added with certain anti ultraviolet and anti-aging additives, reoriented and arranged in a linear state through uniaxial stretching, extruded and pressed into thin plates, punched into regular pore networks, and then stretched longitudinally.

Geogrid is a kind of main geosynthetics. Compared with other geosynthetics, it has unique performance and efficacy. It is often used as reinforcement of reinforced soil structure or reinforcement of composite materials.Geogrids are divided into four categories: Plastic geogrids, steel plastic geogri
