Biaxial Geogrid

Biaxial geogrids are high-performance polymer grids designed with equal strength in both machine and cross-machine directions. These engineered materials feature integrally formed ribs and apertures (typically 15-50mm) that create optimal interlock with granular soils, delivering superior stabilization for demanding civil engineering applications.

Key Advantages

1. Bidirectional Load Distribution

   • Balanced tensile strength (15-30kN/m in both directions)
   • Reduces differential settlement by up to 70%

2. Enhanced Bearing Capacity

   • Increases CBR values by 3-8 times versus unreinforced soil
   • Allows construction on soft subgrades (<5% soil modulus improvement)

3. Cost Efficiency

   • Reduces aggregate requirements by 30-50%
   • Cuts construction time by 40% through rapid deployment

4. Environmental Compliance

   • 100% recyclable HDPE/PP materials
   • LEED-certified projects eligible

Technical Specifications

• Materials: UV-stabilized HDPE or Polypropylene
• Aperture Stability: ≤5% deformation under 2000h creep test (ISO 13431)
