PET geogrid

PET Geogrid – High-Strength Polyester Geogrid for Soil Reinforcement

Our PET Geogrid (Polyester Geogrid) is manufactured from high-tenacity polyester yarns and coated with a protective layer to deliver exceptional tensile strength, low creep, and long-term durability. It is widely used for road construction, railways, retaining walls, embankments, slope stabilization, soft soil reinforcement, and other civil engineering applications.

With its stable structure, excellent performance under load, and outstanding compatibility with soil, PET geogrid significantly improves bearing capacity, reduces settlement, and increases the service life of engineering structures while lowering overall construction costs.

 What Is PET Geogrid?

PET geogrid is a high-strength geosynthetic material made from polyester yarns through a weaving and tensile orientation process.
It is available in uniaxial and biaxial configurations.

Its primary functions include:

  • Soil reinforcement

  • Increasing structural stability

  • Improving load distribution

  • Reducing deformation

  • Extending road and foundation lifespan

Due to its low creep performance, PET geogrid is ideal for applications requiring long-term load-bearing capacity.

🟦 Installation Guide

Step 1: Site Preparation

Clear debris, vegetation, and level the ground.

Step 2: Laying the Geogrid

  • Place in the correct direction (MD/TD as required)

  • Pull tight to remove wrinkles

Step 3: Anchoring / Fixing

Secure using U-pins, sandbags, or compaction equipment.

Step 4: Overlap

  • Standard overlap: 20–30 cm

  • Soft soil: 40–60 cm

Step 5: Backfilling & Compaction

Backfill in layers and compact evenly for optimal performance.

🟦  FAQ:

Q1: Is PET geogrid stronger than HDPE geogrid?

Yes. PET geogrid offers higher tensile strength and better long-term creep performance than HDPE geogrid, making it ideal for heavily loaded structures.

Q2: How long does PET geogrid last?

Under typical soil and environmental conditions, PET geogrid can last 50–100 years.

Q3: Can PET geogrid be used for slope reinforcement?

Absolutely. It is widely used in slope stabilization and erosion control applications.

Q4: What roll sizes are available?

Most common widths range from 3.9 m to 5.8 m, with custom roll lengths available.

Q5: Do you offer samples?

Yes, samples are available upon request.
