Product Description
Sodium bentonite geosynthetic clay liner (GCL) is an advanced environmental and ecological composite impermeable material engineered for superior seepage prevention across multiple engineering applications.
Product Overview
This innovative waterproof blanket combines graded natural sodium bentonite particles with specialized admixtures, securely fixed between geotextile and plastic woven cloth using advanced needling technology.
Key Properties
Sodium bentonite exhibits exceptional water-swelling characteristics, forming a high-density gel upon hydration to deliver outstanding anti-seepage performance. The material provides comprehensive sealing, isolation, and reinforcement functions while offering strong self-healing capabilities, simplified installation, and excellent long-term durability.
Application Areas
- Landfill containment systems
- Artificial lakes and reservoirs
- Water channels and river projects
- Roof gardens and green infrastructure
- Basements and underground structures
- Metro tunnels and underground passages
- Various civil engineering seepage prevention projects
