Product Description
High-Performance Needle-Punched Sodium Bentonite Blanket
Cost-effective anti-seepage solution for demanding engineering applications
Product Overview
The Needle-Punched Sodium Bentonite Waterproof Blanket (GCL-NP) is a high-performance anti-seepage geosynthetic material engineered for superior waterproofing performance. Composed of high-swelling sodium bentonite particles securely sandwiched between two layers of geotextiles and bonded through advanced needle-punching technology, this innovative solution prevents particle displacement while ensuring uniform anti-seepage capabilities.
This product serves as an economical and reliable alternative to traditional compacted clay liners and geomembranes, meeting JG/T 193 standards with unit area mass options ranging from 4000g/m² to 6000g/m².
Key Features & Benefits
  • Excellent flexibility that adapts to irregular terrains and foundation deformations without cracking, effectively repairing cracks up to 2mm in concrete surfaces
  • Durable waterproof performance with sodium bentonite swelling 15-17 times its volume when encountering water, forming a dense colloidal waterproof layer with vertical permeability coefficient ≤5*10⁻¹¹ cm/s
  • Easy construction requiring no heating or bonding, suitable for installation on damp substrates (no standing water) and even at temperatures as low as -20℃, significantly reducing construction timelines
  • Eco-friendly and non-toxic composition using natural inorganic bentonite, harmless to humans and environment, with exceptional long-term durability and resistance to aging or corrosion
Applications
Ideal for projects requiring cost-effective and rapid anti-seepage solutions across multiple sectors:
  • Municipal engineering applications including underground garages and roof greening systems
  • Water conservancy projects such as irrigation canals and artificial lakes
  • Environmental protection projects including domestic waste landfills and sewage treatment pools
Reinforced Laminated GCL: Enhanced double anti-seepage protection specifically designed for harsh environmental conditions and demanding applications.
