What is a Coated SBR Reinforcement Polyester Geogrid?
It's a composite geosynthetic material engineered for superior performance. Let's dissect its name:
1.Polyester Geogrid (The Core):
Material: Made from high-tenacity polyester (PET) yarns.
Structure: The yarns are woven or knitted into a grid-like pattern (apertures) and then coated.
This open structure allows for excellent interlock with soil and aggregate.
Key Property: Polyester has exceptionally high tensile strength and very low creep.
Creep is the tendency of a material to deform permanently under a constant load over time.
This is the single most important property for long-term stabilization projects like railways and highways.
2. SBR Reinforcement Coating (The Protective Layer):
Material: SBR (Styrene-Butadiene Rubber) is a synthetic rubber known for its durability, flexibility,
and resistance to abrasion.
Function: The coating is applied to the polyester core to:
Protect against Installation Damage: During construction, rocks and aggregate can be sharp.
The tough rubber coating shields the sensitive polyester yarns from cuts, abrasion, and punctures.
Improve Friction with Soil: The rubbery texture provides a higher coefficient of friction with the surrounding
soil/aggregate, enhancing the interlock and load transfer.
Provide Additional Durability: It offers better resistance to chemicals and environmental factors.

Yixing Shenzhou Geosynthetics Coated SBR Reinforcement Polyester Geogrid is a premium geosynthetic solution
designed for the most demanding infrastructure projects. Its combination of:
High-Strength, Low-Creep Polyester Core for long-term stability, and
Abrasion-Resistant SBR Coating for durability during installation and service,
makes it an ideal choice for reinforcing the foundations of railways and highways.
It transforms a weak, two-layer system (soil + aggregate) into a strong, composite,
three-layer system (soil + geogrid + aggregate), leading to a more durable, long-lasting, and cost-effective infrastructure asset.
Polyester Geogrids Application :
PVC-coated 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.
