Warp Knitted Grid Mesh Size 50.8mm Polyester Biaxial Geogrid Base
Reinforcement Of Unpaved And Paved Roads
What is a Polyester Biaxial Geogrid?
It is a high-strength synthetic grid made from high-tenacity
polyester (PET) yarns,
woven and coated to create a grid structure with large, open
apertures.
The key term "biaxial" means that it is engineered to have
significant tensile strength and stiffness
in two perpendicular directions—typically along the machine
direction (roll length) and the cross-machine direction (roll
width).
This equalizes stress distribution in a plane, making it ideal for
stabilizing weak subgrades and spreading loads over a wider area.
Comparison with Other Geogrid Types :
vs. Uniaxial Polypropylene (PP) Geogrids:
Polyester is stronger and has much better creep resistance than PP,
making it the preferred choice for permanent, critical structures.
PP is more cost-effective for smaller, temporary, or less critical
applications.
vs. Biaxial Geogrids:
Biaxial geogrids have strength in two perpendicular directions and
are used for
base reinforcement of roads, parking lots, and platforms where
loads are applied
from multiple directions. Uniaxial is specialized for
one-directional reinforcement in walls and slopes.

Polyester Biaxial Geogrid are used in applications :
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.
