High Tensile Strength UV Resistance Roll 3.95x100M Uniaxial Woven
Polyester Geogrid Reinforced Steep Slope
Overview of Uniaxial Woven Polyester Geogrid:
Uniaxial Woven Polyester Geogrid Key Characteristics and Properties :
High Tensile Strength & Low Elongation:
The primary advantage.
Polyester has a very high tensile strength and a very low strain
(elongation) at peak load,
typically between 10% and 13%.
This means it can withstand enormous pulling forces without
stretching excessively, providing excellent restraint.
Uniaxial Strength Orientation:
Its structure is optimized to provide maximum strength in one
direction (the "machine direction"),
with significantly lower strength in the perpendicular direction
(the "cross-machine direction").
Durability:
Excellent Creep Resistance: Polyester has superior resistance to
creep (long-term stretching under constant load)
compared to polypropylene (PP) or high-density polyethylene (HDPE)
geogrids. This is critical for permanent structures.
Robust Coating:
The polymer coating protects the sensitive polyester fibers from
installation damage, abrasion, UV radiation, and chemical attack
from soil environments.
Aperture Stability:
The rigid, coated junctions provide excellent interlock with
granular fill materials (like gravel, crushed stone, or soil).
Flexibility:
Despite its high strength, it is flexible enough to be rolled and
unrolled, conforming to subgrade irregularities during
installation.
Primary Functions in Geotechnical Engineering:
The main function of a uniaxial geogrid is Reinforcement. It works
through two primary mechanisms:
Lateral Restraint: The geogrid interlocks with the soil/aggregate
particles.
When a load is applied (e.g., from a road or embankment), the soil
tries to move laterally.
The geogrid, with its high tensile strength, resists this movement,
effectively confining the soil
and improving its load-bearing capacity.

Polyester Geogrids Application :
The Knitted BX PET Polyester Geogrid is a versatile workhorse used
in many of the applications we've already discussed:
Road and Highway Base Reinforcement:
Placed on the subgrade before the aggregate base course is laid.
It confines the aggregate, reduces rutting, and allows for a
thinner base layer, leading to significant cost savings.
Railway Track Bed Stabilization:
Placed between the subgrade and the ballast layer.
It prevents the ballast from penetrating the soft subsoil and the
subsoil from pumping up into the ballast,
maintaining track geometry and reducing maintenance.
Foundation Mattresses for Embankments:
Used to build stable embankments over very soft soils by
distributing the load over a wider area.
Soil Stabilization for Working Platforms:
Creates a stable platform for construction equipment on sites with
weak soils.
Note on Retaining Walls: While exceptionally strong, a standard
biaxial (BX) geogrid is often used for
stabilization. For the highest, most critical retaining walls, a
uniaxial geogrid (which concentrates strength
primarily in one, longitudinal direction) is often preferred, as
that is the direction of the tensile forces
in an MSE wall. However, BX grids are still successfully used in
many wall applications.

Yixing Shenzhou Geosynthetics Polyester Geogrid Design and Construction Workflow:
Site & Soil Analysis: Geotechnical engineers analyze the soil
conditions, loads, and required wall height.
Design: Engineers specify the geogrid type (polyester), its
strength, length, and vertical spacing between layers.
The length is crucial for creating a stable reinforced zone.
Construction:
A leveling pad is prepared.
The first layer of wall facing units is placed.
A layer of select backfill is placed and compacted.
The polyester geogrid is rolled out over the compacted soil and
connected to the wall face.
The process repeats: backfill, compact, place geogrid, until the
top is reached.
