Geogrid is a primary geosynthetic material, possessing unique properties and functions compared to other geosynthetics. It is commonly used as reinforcing material for soil structures or composites. Geogrids are categorized into four main types: plastic geogrid, steel-plastic geogrid, glass fiber geogrid, and glass fiber polyester geogrid.
Plastic Geogrid
Due to the polymer's high molecular reorientation during the heating and extension process in the manufacturing of plastic geogrids, the intermolecular bond strength is enhanced, thereby increasing its strength. The elongation rate is only 10% to 15% of the original sheet. Adding anti-aging materials such as carbon black to the geogrid can provide excellent resistance to acids, alkalis, corrosion, and aging, enhancing its durability.
Bidirectional Geotextile Grid
The bidirectional geogrid is formed by extrusion, sheet formation, and punching processes, followed by longitudinal and transverse stretching of high molecular polymer. This material boasts significant tensile strength in both directions, offering an ideal interlocking system for force distribution and diffusion within the soil, making it suitable for large-area load-bearing foundations.
Unidirectional Geogrid
Unidirectional geogrid is formed by extruding and pressing high molecular polymer into a thin plate, followed by punching regular holes to create a woven mesh, which is then stretched longitudinally. This process aligns the high molecular polymer into a directional linear state, forming a uniformly distributed, high-node-strength, long elliptical mesh structure. This structure boasts a high tensile strength and modulus, with our products demonstrating high early-stage (elongation of 2% to 5%) tensile strength and modulus. It provides an ideal force-bearing and diffusive连锁 system for soil. The product has a large tensile strength (>150 Mpa), suitable for various soils, and utilizes reinforced reinforcement materials.
Steel-plastic geogrid
Steel-plastic geogrids are made of high-tensile steel wire (or other fibers), specially treated, blended with polyethylene (PE), and supplemented with other additives, then extruded to form a composite high-tensile tensile strip with rough embossed patterns, known as high-strength reinforced geotextile tape. From this single strip, by weaving or interlacing longitudinally and laterally at certain intervals, and using special reinforced bonding welding technology to weld the junction points, a reinforced geogrid is formed.
Glass Fiber Geogrid
Glass fiber geogrid is a woven mesh structural material made from glass fiber, a special composite geosynthetic material treated with a unique coating process to protect the glass fiber and enhance overall performance. The main components of glass fiber are silicon dioxide, an inorganic material with extremely stable physical and chemical properties. It features high strength, high modulus, wear resistance, frost resistance, no long-term creep; good thermal stability; the mesh structure allows for aggregate interlocking and restraint; and improves the load-bearing capacity of asphalt mixtures. The special modified asphalt coating on the surface endows it with dual composite properties, enhancing the wear resistance and shear strength of the geogrid.
