50.8x50.8mm Grid Mesh Size 200-30 KN/M Uniaxial Polyester Geogrid Reinforcement of weak ground For Transportation
Why This 200-30KN/M Polyester Geogrid Specification Matters ?
Economical for Massive Structures: Using a single layer of 200 kN/m geogrid can be more cost-effective
and faster to install than multiple layers of a lower-strength geogrid (e.g., 80 kN/m), reducing the number
of lifts and the amount of compaction required.
Enables Ambitious Designs: It allows engineers to design and build earth structures that were previously
only feasible with massive concrete gravity walls or complex soil nailing/anchoring systems.
Proven Reliability: The combination of polyester's material properties and the integral structure of the geogrid
provides a predictable and reliable material for critical permanent works.
Polyester (PET) Geogrid Key Characteristics:
This nomenclature directly refers to the geogrid's ultimate tensile strength per meter of width,
as determined by standardized test methods (e.g., ASTM D6637).
200 kN/m: This is the strength in the primary, longitudinal (machine) direction.
Context: 200 kilonewtons per meter is an extremely high capacity. To visualize,
200 kN is roughly equivalent to holding a tensile force of 20,000 kg (or 20 metric tons) for
every single meter width of geogrid. This is the working direction of the geogrid.
30 kN/m: This is the strength in the secondary, transverse direction.
Context: This is significantly lower because the geogrid is engineered to be uniaxial.
This secondary strength is primarily to maintain the geogrid's geometry and integrity during
handling and installation, not for carrying primary loads.
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.
