Product Overview
Our 4-6m wide high swelling self-healing sodium bentonite waterproof blanket (GCL) is a premium inorganic geosynthetic anti-seepage material for permanent waterproof projects. Produced by encapsulating high-purity sodium bentonite between double-layer reinforced geotextiles via professional needle-punching process, this wide-size GCL features excellent water swelling performance and automatic self-repairing capability. Without any chemical adhesive, it forms a dense waterproof colloid layer after contacting water, delivering stable and long-lasting anti-seepage effects. The optimized wide-width design greatly improves laying efficiency while ensuring integral waterproof structure, making it a reliable permanent anti-seepage solution for large-scale civil and environmental engineering.
Core Advantages & Key Features
High Swelling Self-Healing Performance: Adopting high-grade sodium bentonite raw material, the blanket features powerful water absorption and swelling capacity. It can automatically fill tiny punctures, construction gaps and foundation cracks, realizing self-healing and eliminating hidden leakage risks permanently.
4-6m Ultra-Wide Efficient Laying Design: Standard 4m to 6m wide specification effectively reduces splicing times and joint leakage points during construction. It covers larger construction area at one time, simplifies laying procedures and greatly improves overall project construction efficiency.
Permanent Stable Anti-Seepage Effect: As a pure natural inorganic mineral material, the bentonite layer will not age, degrade or fail with long-term buried use. It maintains ultra-low permeability and stable waterproof performance, achieving lifelong anti-seepage protection for engineering structures.
Strong Environmental Adaptability: The composite GCL structure resists corrosion, extreme temperature and foundation deformation. It adapts to various complex soil and water environments, keeping intact structural and waterproof performance in harsh engineering conditions.
Eco-Friendly & Zero Pollution: Free of chemical additives and toxic substances, the product conforms to international environmental protection standards. It causes no secondary pollution to soil and groundwater, suitable for ecological and environmental protection engineering projects.
Cost-Effective & Low Maintenance: Featuring simple construction, no complex processing and long service life, it effectively cuts down construction labor cost and later maintenance investment with outstanding comprehensive economic benefits.
Application Scenarios
Widely applied in municipal landfill anti-seepage and closure, tailings pond and reservoir anti-leakage, artificial lake and wetland ecological waterproofing, underground structure waterproofing, river course renovation, foundation anti-seepage and other projects requiring permanent and high-standard anti-seepage performance.
