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.
