Product Description
Flexible GCL: Adapt to Irregular Terrain for Tunnel and Subway Anti-Seepage
Our Geosynthetic Clay Liner (GCL) offers exceptional flexibility and adaptability, designed to conform precisely to irregular surfaces. The material can be freely bent, cut, and laid according to terrain contours, ensuring complete surface contact without cracks or gaps. Even with uneven foundation settlement, the GCL maintains structural integrity, with internal bentonite capable of self-repairing cracks up to 2mm to preserve anti-seepage performance.
Advanced Production Process

Our manufacturing process is specifically optimized for irregular terrain applications. The geotextile surface features anti-slip treatment to enhance friction between the GCL and base surface, preventing displacement during installation. Precision spreading equipment ensures uniform bentonite distribution, while increased needle punching density (200 punches/m²) prevents agglomeration and flow. Finished products are rolled with flexible cores to protect against damage during transport and uncoiling.

Technical Specifications

Compliant with ASTM D6363-17, EN ISO 13760:2019, and GB/T 17642-2011 standards:

Parameter Specification
Bending Radius ≤ 50 cm (no damage)
Tensile Strength (Longitudinal/Transverse) ≥ 7.0 kN/m
Elongation at Break ≥ 12% (both directions)
Peel Strength ≥ 50 N/100mm
Permeability Coefficient ≤ 3×10⁻¹¹ m/s
Operating Temperature Range -20℃ to 60℃ (suitable for low-temperature construction)
Standard Dimensions Width: 4-5m, Length: 30-50m (customizable to project requirements)
Application Scenarios

Specifically engineered for underground engineering applications with irregular terrain, including:

  • Tunnel and subway anti-seepage systems
  • Underground utility corridors
  • Basement waterproofing
  • Slope and embankment protection
  • Complex terrain projects where traditional waterproof materials face installation challenges

This flexible GCL solution addresses the limitations of conventional waterproof materials, providing superior adaptability and reliable performance in demanding construction environments.
