1. Overlaps self-seal without adhesives.
2. Vertical installation capability.
3. 100% natural sodium bentonite core.
Product Introduction:
Haoyang Environmental's cold-weather geocomposite features a specially formulated bentonite core that maintains swelling capacity (≥18mL/2g) at temperatures as low as -25°C, verified through 100 freeze-thaw cycles (ASTM D7322). The frost-resistant polypropylene geotextile layers incorporate crystalline anti-freeze additives that prevent fiber embrittlement, with field data from Siberian installations showing 98% retention of tensile strength after five winter seasons. This engineered solution achieves ≤5×10⁻¹⁰ m/s permeability in permafrost conditions while withstanding 50kPa shear stresses on 3:1 slopes.
Our triple-layer erosion control system combines a high-swelling sodium bentonite core (5kg/m²) with needle-punched PET geotextiles (400g/m²) and UV-stabilized netting, creating a durable yet flexible matrix for slope stabilization. The composite structure demonstrates 85% vegetation establishment within 12 months (ASTM D7322) while reducing soil loss by 90% compared to conventional methods (ASTM D6459). Pre-cut panels (2m×5m) with biodegradable stitching allow rapid deployment in challenging terrain, with the bentonite layer activating upon first rainfall to form an impermeable barrier.
Engineered Applications
1. Urban Green Infrastructure:
30mm thick drainage composites reduce roof loads by 40% versus granular systems.
