Self-Sealing Sodium Bentonite Waterproof Blanket with 4-6m Width and ≥24ml/2g Swelling Index for Reliable Waterproofing
Product Description
Self-Sealing Sodium Bentonite Waterproof Blanket
This advanced geosynthetic clay liner (GCL) utilizes high-purity sodium bentonite as the core waterproofing material, delivering exceptional self-sealing and anti-seepage performance for complex engineering applications where water leakage presents significant challenges.
Advanced Composite Structure
The scientifically engineered three-layer construction ensures optimal performance:
Upper and Lower Non-Woven Geotextiles: Provide protection and water permeability, allowing rapid water contact with the bentonite layer
Middle Bentonite Layer: Evenly distributed, high-density sodium bentonite that swells rapidly upon water contact to form a dense impermeable barrier
Superior Performance Characteristics
Excellent puncture resistance for protection against sharp objects
Superior aging and chemical corrosion resistance
Maintains stable performance in harsh environmental conditions
Exceptional flexibility and foundation settlement adaptability
Accommodates slight foundation deformation without cracking or leakage
Lightweight design for easy transport and installation
Application Areas
Ideal for demanding waterproofing applications including:
Landfill bottom liners and containment systems
Roof garden and green roof waterproofing
Tunnel and underground structure waterproofing
Riverway renovation and water channel projects
Basement and below-grade waterproofing systems
Installation Specifications
Overlapping installation requires 15-20cm overlap between adjacent blankets. Secure using mechanical fixing or adhesive methods. For enhanced joint impermeability, apply bentonite paste to seal connections. This efficient installation process reduces labor intensity and improves construction efficiency while ensuring long-term waterproof performance.
