Flexible Geosynthetic Clay Liner Adapts to Irregular Terrain for Tunnel and Subway Anti-Seepage
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.
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) |
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.
