Polyester geogrid is made from polyester fiber as the raw material. It adopts a warp-knitted directional structure, where the warp and weft yarns in the fabric are in a non-bent state relative to each other, and the intersection points are bound together with high-strength filament fibers, forming firm connection points that leverage their mechanical properties. Warp-knitted polyester geogrid offers high tensile strength, low elongation, high tear resistance, minimal difference in longitudinal and transverse strength, resistance to UV aging, abrasion, and corrosion, light weight, strong interlocking with soil or gravel, and plays a significant role in enhancing soil shear resistance and reinforcing the integrity and load-bearing capacity of the soil mass.

Features:

1. High tensile strength

2. Low elongation rate

3. Resistance to erosion and aging

4. Strong interlocking with base materials

5. Lightweight with drainage function

Applications:

1. Warp-knitted polyester geogrid is used for reinforcing soft soil subgrades in highways, railways, municipal roads, and various other road types, effectively improving subgrade strength and delaying reflective cracking.

2. It is applied in hydraulic engineering for reinforcing embankments and river channels, isolating and stabilizing soft soil foundations, enhancing protective capabilities, and improving foundation bearing capacity and stability.

3. Used for slope reinforcement of embankments and retaining walls, enhancing overall strength, and reinforcing soft soil foundations in highways, railways, and water conservancy projects.

4. Employed in railway ballast protection: Prevents ballast loss caused by train vibrations and weather exposure by wrapping the ballast with geogrid, thereby improving subgrade stability.

5. Utilized in railway retaining walls: Reinforces retaining walls along railways, such as platforms and freight docks within stations, extending service life and reducing maintenance costs.

6. Applied in reinforced retaining walls: Adding geogrid layers alongside highways and in vertical retaining walls enhances their load-bearing capacity.

7. For bridge abutment foundations, which are prone to settlement causing bumpy transitions, laying geogrid under the foundation improves bearing capacity and stabilizes the abutment.
