Product Description
High-Performance Needle-Punched Sodium Bentonite Blanket
Cost-effective anti-seepage solution for industrial and environmental applications
Product Overview
The Needle-Punched Sodium Bentonite Waterproof Blanket (GCL-NP) is a high-performance geosynthetic anti-seepage material engineered with advanced needle-punching technology. This innovative solution provides reliable waterproofing while offering significant cost savings compared to traditional methods.
Technical Construction
Composed of high-swelling sodium bentonite particles securely encapsulated between two layers of geotextiles and bonded through precision needle-punching. This advanced manufacturing process ensures bentonite particles remain firmly locked in place, preventing displacement and delivering consistent, uniform anti-seepage performance throughout the material.
Manufactured in compliance with JG/T 193 standards, available in unit area mass ranging from 4000g/m² to 6000g/m² to meet diverse project requirements.
Key Performance Features
  • Superior Flexibility: Conforms seamlessly to irregular terrain and accommodates foundation deformations without cracking. Effectively repairs concrete surface cracks up to 2mm wide.
  • Exceptional Waterproofing: Sodium bentonite expands 15-17 times its original volume upon water contact, forming a dense, impermeable colloidal barrier with vertical permeability coefficient ≤5*10⁻¹¹ cm/s.
  • Simplified Installation: Requires no heating or bonding agents. Can be installed on damp substrates (without standing water) and in temperatures as low as -20℃, significantly accelerating project timelines.
  • Environmental Safety: Manufactured from natural inorganic bentonite, completely non-toxic and harmless to humans and ecosystems. Offers long-term durability with no aging or corrosion concerns.
Application Areas
Ideal for cost-effective, rapid deployment anti-seepage solutions across multiple sectors:
  • Municipal Engineering: Underground parking structures, rooftop green spaces, and urban infrastructure
  • Water Management: Irrigation channels, artificial lakes, reservoirs, and canal lining
  • Environmental Protection: Landfill containment systems, wastewater treatment facilities, and pollution control projects
Reinforced Laminated GCL Option
For demanding applications in harsh environments, our reinforced laminated GCL provides enhanced double-layer anti-seepage protection with increased durability and performance under extreme conditions.
