How To Understand: "Knitted BX PET Polyester Geogrid" ?
1. PET Polyester:
This is the base material, as discussed before. Polyester (PET -
Polyethylene Terephthalate) is chosen
for its high tensile strength and, most critically, its extremely
low creep characteristics, making it suitable
for permanent, heavy-load applications.
2. Knitted:
This describes the manufacturing process. Unlike woven or extruded
geogrids, this type is produced
by a knitting process, similar in concept to textiles.
High-tenacity polyester yarns are looped and interlocked in a
precise pattern on a large knitting machine.
Key Advantage of Knitting: This process creates a very stable,
dimensionally secure grid that is highly resistant
to unraveling if the yarn is cut or damaged at the edge. The loops
can redistribute load effectively.
3. BX:
This is the most specific part and indicates the aperture geometry
and structure.
The "B" typically stands for "Biaxial," meaning it provides
strength in two directions – both the machine
direction (longitudinal) and the cross-machine direction
(transverse).
The "X" refers to the specific rectangular or square aperture shape
and the nodal structure that connects the
ribs. You can think of "BX" as a common industry designation for a
standard biaxial geogrid with a specific
rib and junction configuration.

Polyester Geogrids Application :
Polyester geogrids are used in all major reinforcement
applications,
especially where long-term performance is critical:
Reinforced Soil Retaining Walls (MSE Walls):
The primary application, where they provide the tensile strength to
hold the soil mass together.
Steep Slope Reinforcement: Stabilizes slopes at angles steeper than
natural soil would allow.
Basal Reinforcement over Soft Soils:
Used to construct embankments and roads over soft, compressible
ground by distributing
loads and providing a stable platform.
Landfill Liners and Capping Systems:
Reinforces the sides and covers of landfills, providing stability
to the composite liner system.
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.
