Triaxial geogrid is a high-performance polymer grid (typically polypropylene or polyester) with triangular apertures, engineered for multidirectional load distribution. Unlike conventional biaxial grids, its hexagonal structure delivers 360° stress transfer, making it ideal for weak subgrade conditions.
Key Features
- Triangular Geometry
- Aperture angles (120°) optimize interlock with aggregates, achieving 20-30% higher confinement efficiency than rectangular grids (per ASTM D6637).
- Multiaxial Strength
- Equal tensile strength (10-30kN/m) in all directions, eliminating weak axes common in biaxial products.
- Installation Advantages
- Lightweight rolls (30-50kg/roll) enable 50% faster deployment vs. traditional methods.
- Compatible with all soil types (CL, ML, SP per USCS classification).
- Durability
- UV-stabilized formulations retain >85% strength after 10,000 hours (ISO 13426).
- Resistant to chemical/biological degradation (pH 2-12).
Applications
- Road Construction: Reduces base course thickness by 40% while extending pavement life (AASHTO M288 compliant).
- Slope Stabilization: Factor of safety (FOS) improvement up to 1.8× vs. unreinforced slopes.
- Railway Ballast: Decreases track settlement by 60% (tested per EN 15381).
