Polyester Geogrid – High Strength PET Geogrid for Road and Slope Reinforcement

• High Tensile Strength；Manufactured from high-tenacity polyester yarns, Polyester Geogrid provides exceptional tensile strength for soil reinforcement and load distribution.

• Low Elongation；Maintains structural stability under heavy loads with minimal deformation, ensuring long-term performance.

• Excellent Creep Resistance；Designed to withstand continuous loads over extended periods, making it ideal for permanent civil engineering structures. 

• Superior Soil Interlock；The optimized grid structure enhances interaction between the geogrid and surrounding soil, improving overall stability.

• Outstanding Durability；Resistant to environmental aging, weathering, and mechanical damage, ensuring a long service life.

• UV Resistance；Protective PVC or polymer coating provides excellent resistance to ultraviolet exposure during installation and service.

Transportation Infrastructure (Roads, Railways, and Airports)

• This is the most common application field. The geogrid acts as a reinforcement interlayer within the pavement structure.

• Asphalt Pavement Reinforcement (Anti-Reflective Cracking): Placed between the old concrete pavement and the new asphalt overlay. The low elongation (≤10-12%) of polyester geogrid absorbs tensile stresses, preventing cracks from the old layer reflecting up through the new asphalt.

• Subgrade Strengthening (Soft Soil): When laid on weak or swampy foundations, the grid "locks" with the aggregate above. This increases the bearing capacity, reducing rutting and differential settlement. 

• Railway Ballast Reinforcement: Placed beneath railway tracks to stabilize ballast (crushed stones), reducing lateral movement and reducing maintenance frequency.

Slope & Embankment Engineering

• When constructing steep slopes or widening existing embankments, gravity alone is insufficient to hold the soil.

• Steep Slope Stabilization: The geogrid is laid in horizontal layers within the slope fill. As the soil tries to slide downward, the grid grips the soil particles, creating a reinforced "soil mass" that stands at steeper angles (e.g., 70° instead of 45°).

• Embankment Widening: When adding lanes to a highway, new fill placed on the old slope tends to slide off. Polyester geogrid ties the new fill to the existing embankment, preventing separation.

Retaining Walls (MSE Walls)

• Mechanically Stabilized Earth (MSE) walls rely almost entirely on geogrids to hold back soil.

• Wrap-Face Walls: The geogrid is rolled out, the soil is placed, and the excess grid is folded back over the soil (like wrapping a present) to create a green or vegetated wall face.

• Modular Block Walls: The grid is attached to concrete blocks (the wall face) and extends deep into the backfill. The weight of the soil on the grid holds the wall upright.

OEM & ODM Services

• Beyond product specifications, many suppliers provide OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services . This includes:

• Custom Packaging: Logo, labels, and packaging design for distributors or branded product lines.

• Custom Sizes: Non-standard dimensions not listed in regular catalogs.

• Private Labeling: Your company 

Sample & Lead Time Information

• Before committing to a large order, you can typically request samples to verify quality :

• Samples: Usually provided free of charge.

• Lead Time: Generally 3–20 days after order confirmation, depending on production schedule and order quantity

• Raw material preparation: Select high-quality polyester fiber and undergo strict quality inspection.

• Warp knitting process: Use advanced warp knitting equipment to weave polyester fiber into a mesh structure.

• Surface treatment: Coat the surface of the grille to improve its corrosion resistance and anti-aging performance.

• Quality inspection: Strict quality inspection of finished products to ensure that the products meet national standards and customer requirements.

• Product quality certification: Passed ISO9001 quality management system certification, CE certification, etc.

• Product test report: Provide product test reports issued by authoritative organizations.

Q1: What is Polyester Geogrid?

A: Polyester geogrid is a high-strength geosynthetic material used for soil reinforcement and stabilization. It is manufactured from high-tenacity multifilament polyester yarns that are precision-knitted into a dimensionally stable grid structure, then coated with a protective polymer (such as PVC, bitumen, or latex) for enhanced durability . It is sometimes referred to as "fiber soft steel" due to its high tensile strength and low elongation .

Q2: What are the main types of Polyester Geogrid?

A: Polyester geogrids are available in two primary configurations :

Biaxial Geogrid: Equal tensile strength in both the warp (machine) and weft (cross) directions (e.g., 30 kN/m × 30 kN/m, 50×50, up to 300×300). Used for applications requiring load distribution in multiple directions, such as road bases and pavement reinforcement.

Uniaxial Geogrid: Significantly higher strength in one direction (e.g., 100 kN/m × 30 kN/m, up to 400×50). Used for retaining walls and steep slopes where the load is primarily in a single direction.
