Yixing Shenzhou Polyester Geogrid 200-50Kn/M
1.Material: Polyester (PET)
Low Creep (Critical): The essential property for this strength class. It ensures the geogrid will not stretch
significantly over decades under these extreme loads, guaranteeing the structure's long-term integrity (75-100+ year design life).
High Tensile Modulus: It is very stiff, resisting elongation under load to minimize deformation.
Durability: Excellent resistance to chemical and biological degradation in soil.
2.Structure: Uniaxial
Despite the high transverse strength, this is still a uniaxial geogrid.
The primary function is to carry load in one direction.
The ribs in the longitudinal direction are the main load-bearing elements.
Why the Higher Transverse Strength PET Geogrid(50 vs. 30) Matters?
Enhanced Durability & Damage Resistance: The higher transverse strength makes the geogrid
more robust against installation damage (e.g., from sharp rocks or equipment).
It is less likely to tear or be compromised during backfilling and compaction.
Handling of Multi-Directional Stresses: In complex structures like very tall walls or slopes,
there can be unexpected stress redistributions, arching effects, or localized failures.
The higher transverse strength provides a greater margin of safety against these unpredictable forces.
Improved Interlock: The stronger transverse ribs can contribute to a better mechanical interlock with the soil,
creating a more coherent reinforced soil mass.
Yixing Shenzhou Polyester Geogrids :
UX Uniaxial Polyester Geogrids:
Stronger in one direction, used for reinforcement in specific directions, such as retaining walls.
BX Biaxial Polyester Geogrids:
Strong in both directions, suitable for applications requiring reinforcement in all directions, like embankments and slopes.
How Uniaxial Geogrids Work ?
Soil Reinforcement:
Uniaxial geogrids are placed between soil layers, providing tensile strength in one direction, which helps to reinforce the soil and improve its overall stability.
Load Distribution:
They distribute loads over a wider area, reducing stress on individual soil particles and preventing settlement or failure.
Erosion Prevention:
By reinforcing the soil, they help prevent erosion, particularly on slopes and embankments

Uniaxial Polyester Geogrids Applications:
This geogrid is not for standard projects; it is reserved for mega-scale and critical reinforcement:
Very Tall Mechanically Stabilized Earth (MSE) Walls: This is the primary application.
It is used for walls exceeding 12-15 meters (40-50 feet) in height, and often for walls over 30 meters (100 feet). Examples include:
Highway interchanges and bridge abutments in mountainous terrain.
Retaining walls for port and harbor facilities.
Noise barrier walls along major transportation corridors.
Extremely Steep Slopes: Reinforcing slopes at angles that would be impossible with natural soil,
often in challenging environments where space is severely constrained.
Landfill Infrastructure: Reinforcing the steep sides of modern landfills and supporting heavy liner systems.
Major Infrastructure Support: Used in foundations and support systems for large structures built on or near unstable slopes.
