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.
