Basalt Fiber Geogrid High Tensile Reinforcement For Critical Infrastructure
Volcanic rock-engineered geosynthetics with polymer-modified asphalt coating deliver 40% higher tensile strength than polyester grids. Engineered for heavy-load applications (-260°C to 650°C operational range), our geogrids eliminate long-term creep deformation while reducing roadbed thickness by 35%.
Core Advantages
- Military-Grade Strength: 120kN/m withstands NATO STANAG 4569 LV3 blast loads (0.3% strain at 90kN/m sustained load)
- Zero-Creep Guarantee: 50-year service life with ≤3% elongation under continuous stress (JT/T 1432.1-2022 certified)
- Extreme Climate Resilience: Withstands Arctic permafrost (-260°C) to desert heat (650°C) without cracking
- Rapid Installation: Pre-tensioned rolls deploy 3x faster than steel mesh (400㎡/hour crew efficiency)
