Geogrid Embankment Stabilization Over Soft Soil
Overview of Uniaxial Woven Polyester Geogrid:
What is a Uniaxial Woven Polyester Geogrid?
It is a high-strength, synthetic polymer grid material,
manufactured by weaving high-tenacity
polyester yarns in a specific pattern. The key term "uniaxial"
means its tensile strength
is primarily oriented in a single direction (along the machine
direction or roll length).
This makes it ideal for applications where the primary tensile
forces are expected from one direction.
Uniaxial Woven Polyester Geogrid Advantages Limitations :
1.Very High Tensile Strength Strength is Directional:
Not suitable for applications requiring equal strength in all
directions (for that, biaxial geogrids are used).
2.Excellent Creep Resistance for long-term performance
Sensitivity to pH:
Polyester yarns can be susceptible to hydrolysis (chemical
degradation) in extreme pH environments
(highly alkaline or acidic soils), though modern coatings are
designed to mitigate this.
3.Rigid Apertures for superior soil interlock
Generally more expensive than polypropylene geogrids, but justified
by superior performance.
4.Durable and Robust coating protects fibers
5.Proven Performance in critical, permanent structures

Uniaxial woven polyester geogrids are used in applications where
forces are predominantly in one direction:
Reinforced Soil Walls (MSE Walls):
This is the most common application. The geogrid layers are placed
horizontally between
soil layers to create a stable, reinforced mass that can retain
soil at a steep angle.
Reinforced Steep Slopes: Similar to walls, but for slopes at angles
steeper than what the
soil could naturally maintain. The geogrid provides the necessary
tensile strength to prevent slope failure.
Embankment Stabilization over Soft Soils: When building an
embankment on soft, weak ground,
layers of geogrid are used to prevent circular slip failures and
distribute the load, ensuring global stability.
Foundation Reinforcement:
In some cases, they are used to improve the bearing capacity of
foundations.

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.
