Bentonite waterproof blanket

Product Description

Geosynthetic Clay Liner (GCL) is a high-performance waterproofing material composed of natural sodium bentonite sandwiched between two layers of geotextiles, bonded together through needle-punching technology. In hydraulic engineering, GCLs are extensively used in canals, dams, reservoirs, and artificial lakes for seepage control. The bentonite layer swells upon contact with water, forming a low-permeability gel-like barrier that effectively prevents water infiltration and ensures the stability of hydraulic structures.

Technical Specifications

Features

• Compactness: Sodium bentonite forms a high-density impermeable membrane under water pressure, offering strong self-water-retention properties.
• Permanent waterproofing: As sodium bentonite is a natural inorganic material, it does not degrade or corrode over time or under environmental changes, ensuring long-lasting waterproof performance.
• Easy and fast construction: Compared to other waterproofing materials, its installation is simpler, requiring no heating or adhesion.
• Temperature-resistant: It remains intact even in cold climates without becoming brittle.
• Integration with the structure: The waterproofing material bonds seamlessly with the substrate.
• Eco-friendly: Bentonite is a natural inorganic material, non-toxic and harmless to humans, with minimal environmental impact, making it highly sustainable.

Application

• Municipal Engineering: Seepage prevention for subways, underground structures, and rooftop water storage tanks.
• Environmental & Sanitation: Landfill sites for municipal solid waste, sewage treatment plants, and industrial waste containment.
• Water Conservancy: Seepage control, leakage sealing, and reinforcement for rivers, lakes, reservoirs, and dams.
• Landscaping: Waterproofing for artificial lakes, golf course ponds, and similar applications.
• Petrochemical & Mining: Anti-seepage and leakage prevention in related engineering projects.
