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
Bidirectional Load Distribution
- Balanced tensile strength (15-30kN/m in both directions)
- Reduces differential settlement by up to 70%
Enhanced Bearing Capacity
- Increases CBR values by 3-8 times versus unreinforced soil
- Allows construction on soft subgrades (<5% soil modulus improvement)
Cost Efficiency
- Reduces aggregate requirements by 30-50%
- Cuts construction time by 40% through rapid deployment
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)
