It is a combination of two key components:

  1. Biaxial Geogrid:
    • Made from polypropylene (PP), biaxial geogrids have high tensile strength in both longitudinal and transverse directions.
    • Their primary role is soil reinforcement, distributing loads evenly and enhancing the stability and load-bearing capacity of weak or soft soils.
  2. Nonwoven Geotextile:
    • Typically made from polyester filament, the geotextile is bonded to the geogrid using advanced heat-bonding technology.
    • Its primary functions are separation (preventing the mixing of different soil layers) and filtration (allowing water to pass through while retaining soil particles).

Key Features of Biaxial Geogrid Composites:

  • Heat-Bonded Structure: The geogrid and geotextile are permanently bonded, ensuring a strong and durable connection.
  • Multi-Functionality: Combines the benefits of reinforcement, separation, and filtration in a single product.
  • Versatility: Suitable for applications in roads, railways, embankments, retaining walls, and landfill projects.

Applications:

  • Road Construction: Stabilizing soft subgrades, reducing rutting, and extending pavement life.
  • Railways: Reinforcing trackbeds and preventing soil movement.
  • Embankments and Slopes: Providing stability and preventing erosion.
  • Landfills: Ensuring separation between waste and surrounding soil while maintaining drainage.

Our biaxial geogrid composite is a premium product that combines PP biaxial geogrid and polyester filament nonwoven geotextile, bonded together through advanced heat-bonding technology. This unique construction offers numerous advantages:

  1. Superior Reinforcement and Separation
    The PP biaxial geogrid provides exceptional tensile strength in both directions, reinforcing the soil, while the nonwoven geotextile ensures effective separation and filtration. This dual functionality makes the composite ideal for various soil stabilization applications.
  2. Improved Load-Bearing Capacity
    By distributing loads more evenly, the geogrid component enhances the foundation’s strength, reducing the risk of settlement or deformation, even on weak or soft soils.
  3. Enhanced Durability
    The high-quality PP geogrid and polyester geotextile are heat-bonded, ensuring a strong, durable connection. The composite is resistant to UV radiation, chemicals, and biological degradation, providing long-lasting performance in diverse environments.
  4. Simplified Installation
    The combined geogrid and geotextile design eliminates the need to install two separate layers, saving time and labor during construction. Its lightweight and flexible nature further simplifies handling and installation.
  5. Cost-Effective Solution
    The combination of reinforcement, separation, and filtration in a single product reduces the need for additional materials and aggregate layers, resulting in significant cost savings.
  6. Eco-Friendly Design
    The composite reduces material usage and minimizes environmental impact by optimizing construction processes, making it a sustainable choice for modern infrastructure projects.
  7. Versatile Applications
    Ideal for roads, railways, retaining walls, embankments, and landfills, this composite is a reliable solution for a wide range of soil reinforcement and stabilization challenges.

This innovative combination of PP biaxial geogrid and polyester filament nonwoven geotextile delivers outstanding performance, making it a trusted choice for engineers and contractors worldwide.
