Biaxial Polyester geogrid is a flexible material:
I
Key Characteristics and Components
Material: Polyester (PET)
High Tensile Strength: Polyester yarns have a very high resistance to stretching, allowing them to bear
heavy loads with minimal deformation.
Low Creep: This is a critical property. Creep is the tendency of a material to deform permanently under a
constant load over time. Polyester has excellent long-term creep resistance, making it ideal for permanent structures
like walls and steep slopes.
Excellent Chemical Resistance: It is highly resistant to soil chemicals, alkalis, and microorganisms, ensuring long-term
durability in the ground.
Moderate Acid Resistance: While good against many chemicals, it can be susceptible to strong acids. In such environments,
a protective coating (like PVC) is often applied.
Structure: Biaxial Geogrid (BX)
The grid is manufactured with ribs running in two main directions, creating a network of apertures (openings).
The ribs are integrally formed, meaning the junctions where the ribs meet are punched-drawn or laser-welded from the same sheet of material, creating a robust and locked structure.
This structure provides balanced strength in both the machine direction (MD) and cross-machine direction (CMD), allowing it to handle stresses coming from multiple directions.
Surface: Coated or Uncoated
The raw polyester yarns are often coated with a polymeric material (like PVC or a flexible latex) to:
Protect against installation damage.
Provide enhanced resistance to ultraviolet (UV) light during storage and installation.
Improve friction with soil particles.
How Biaxial Polyester Geogrid Works: The Mechanism
BX Polyester Geogrids function through two primary mechanisms:
Tensile Reinforcement: Soil is strong in compression but weak in tension.
When a geogrid is placed within the soil, it absorbs the tensile forces that the soil cannot,
effectively "holding the soil together."
Lateral Restraint and Interlock: The open apertures of the geogrid allow soil or aggregate particles
to partially penetrate and lock into the grid. This interaction creates a mechanically stabilized composite
zone that distributes loads and confines the soil, preventing lateral spreading.

Polyester Geogrids Application :
1.Roads and Pavements:
Biaxial geogrids are used to reinforce the base of roads and pavements,
enhancing their strength and durability, especially in areas with weak subgrades.
They help distribute loads more effectively and prevent cracking and rutting.
2.Ground Stabilization:
They are used to stabilize ground, particularly in areas with unstable or weak soils,
providing a foundation for construction and preventing settlement.
3.Embankments:
Biaxial geogrids can be used in embankment construction to improve the stability of slopes
and prevent soil erosion.
4.Retaining Walls:
They are used to reinforce retaining walls, providing stability and preventing failure due to soil pressures.
5.Landfills and Leachate Collection Ponds:
Biaxial geogrids can be used to prevent deformation and maintain the structural integrity of landfill caps and to enhance drainage in leachate collection systems.
6.Other Applications:
Biaxial geogrids can also be used in a variety of other applications, such as aggregate reduction, piling platforms, and foundation engineering.
