How Are Geogrids Made?
Geogrids are typically made from polymer materials,including polyester, polypropylene, polyethylene, or polyvinyl alcohol.They can be woven or knitted from yarns,punched into a polymer sheet,extruded through rotating die heads to create a net structure or welded from strips of material.
Punched and drawn geogrids
Molten polymer is extruded into a sheet of defined thickness and a pattern of holes is punched into the sheet.The punched sheet is then stretched in either a single direction to form a uniaxial geogrid or in two directions to form either biaxial or multiaxial geogrids.
Extruded geogrids
Molten polymer is extruded through rotating “die heads” each with a series of “holes” which allow the creation of a “net” type structure.The geometry of the resulting net or geogrid is dependent on the die/extrusion configuration with both uniaxial and biaxial products available.
Welded geogrids
Polymer strips are manufactured and are then bonded together to form a square or rectangular grid shape.The bonding would typically be carried out using heat.
Woven geogrids
Woven geogrids are produced by weaving polymer yarns together, or sometimes knitting polymer yarns together to form a net/grid-like structure.These woven products are often then coated with other polymer materials such as polyvinyl alcohol (PVC) to form the final woven geogrid.
Geogrid/geotextiles composite geogrids
It can be formed by bonding a geotextile separator fabric to the completed geogrid manufactured by the methods above.

Uniaxial Geogrid Features
- Tensile Strength: Uniaxial geogrids(https://geolianyi.com/product/pp-uniaxial-geogrid/)have high tensile strength in one primary direction, known as the machine direction (MD). This strength enables them to withstand significant loads and distribute forces effectively.
- Aperture Size: Uniaxial geogrids(https://geolianyi.com/product/hdpe-uniaxial-geogrid/)feature a regular grid structure with uniform apertures or openings. The aperture size can vary depending on the specific application and desired engineering properties.
- Rib Structure: These geogrids consist of ribs that run in the machine direction and are interconnected by junctions. The ribs provide stiffness and structural integrity, while the junctions facilitate load transfer between adjacent ribs.
- Strain Characteristics: Uniaxial geogrids exhibit low strain characteristics, meaning they have a minimal tendency to deform or elongate under load. This property helps maintain their integrity and load-bearing capacity over time.
- Durability: Geogrids are designed to have excellent resistance to environmental factors such as chemical attack, UV degradation, and biological degradation. This durability ensures long-term performance in various soil conditions.
- Soil Interaction: Uniaxial geogrids form a mechanical bond with the surrounding soil, creating an interlocking effect. This interaction enhances soil reinforcement and provides stability to slopes, retaining walls, and other structures.
7.Installation Efficiency: Uniaxial geogrids are typically supplied in roll form, allowing for easy transportation, handling, and installation. They can be deployed horizontally or vertically, depending on the specific application, and are commonly used in reinforcement layers within soil structures.

Fiberglass Geogrids(https://geolianyi.com/product/fiberglass-geogrids/)Advantages
Slow down reflective cracks: It can suppress stress and release strain. As a hard interlayer with high rigidity, it enhances the tensile and shear resistance of the overlay structure and reduces cracks.
Anti-fatigue cracking: A buffer zone is formed between the stressed areas, allowing the stress to gradually change, reducing the damage caused by sudden stress changes to the asphalt overlay layer. At the same time, the low elongation rate reduces the deflection of the pavement.
High-temperature rutting resistance: It plays a skeletal role in the asphalt surface layer, forming a composite mechanical interlocking system, restricting the movement of aggregates, preventing the asphalt surface layer from pushing, and resisting rutting.
Resistance to low-temperature shrinkage cracking: Enhance the tensile strength of asphalt concrete, resist tensile stress, and even if local cracks occur, the stress can be gradually eliminated through it, preventing the cracks from developing into cracks.
