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 high-swelling sodium bentonite particles encapsulated between two geotextile layers and secured through advanced needle-punching technology. This innovative construction ensures bentonite particles remain firmly locked in place, preventing displacement and delivering consistent, uniform anti-seepage performance across the entire surface.
Key Features & Benefits
Exceptional flexibility that conforms to irregular terrain and accommodates foundation settlement without cracking, capable of sealing cracks up to 2mm in concrete surfaces
Superior waterproof performance with sodium bentonite swelling 15-17 times its volume upon water contact, creating an impermeable gel barrier with vertical permeability coefficient ≤5×10⁻¹¹ cm/s
Simplified installation requiring no heating or bonding agents, suitable for damp substrates (without standing water) and extreme temperatures down to -20℃, significantly reducing construction timelines
Environmentally safe composition using natural inorganic bentonite, non-toxic to humans and ecosystems, with long-term durability resistant to aging and corrosion
Technical Specifications
Compliant with JG/T 193 standards with unit area mass options ranging from 4000g/m² to 6000g/m² to meet various project requirements.
Application Areas
Ideal for municipal infrastructure including underground parking structures and green roofs; water management projects such as irrigation channels and artificial lakes; and environmental protection applications including landfill liners and wastewater treatment facilities. The perfect choice for projects demanding cost-efficient, rapid deployment anti-seepage solutions.
Reinforced Laminated GCL
Enhanced double-layer anti-seepage protection specifically engineered for demanding environmental conditions and challenging project specifications.
