Shandong Hongyue Environmental Protection Materials Co., Ltd. is pleased to announce the launch of our bentonite waterproofing blanket (GCL) product line, engineered to provide reliable, self-healing waterproofing solutions for civil engineering and environmental protection projects worldwide.
Our GCL products combine high-quality sodium bentonite clay between two layers of geotextile (woven and non-woven), creating a robust barrier that swells on contact with water to form an impermeable seal.
Key Product Features:
Self-healing capability — bentonite swells to seal punctures automatically
High impermeability — hydraulic conductivity < 5×10⁻¹¹ m/s
Easy installation — no specialized equipment required
Chemical resistance — stable in various soil conditions
Long service life — 50+ years of reliable performance
Environmentally friendly — natural bentonite, no harmful additives
The unique sandwich structure consists of a layer of sodium bentonite granules encapsulated between a woven and a non-woven geotextile, providing both strength and flexibility.
Typical Applications:
Landfill base and cap liner systems
Reservoir and pond waterproofing
Tunnel and basement waterproofing
Canal and irrigation channel lining
Mining heap leach pad liners
Contaminated site remediation
GCLs are widely used in large-scale environmental projects where reliable waterproofing is critical. The self-healing property ensures long-term performance even under challenging conditions.
“Bentonite waterproofing blankets offer a cost-effective alternative to traditional clay liners and geomembranes,” says Robin, Export Manager at Shandong Hongyue. “The self-healing property is a game-changer for projects where puncture resistance and long-term sealing are critical.”
All GCL products are manufactured in compliance with ISO 9001 quality standards and tested to meet international specifications including ASTM D5887 and GRI-GCL3. Every batch undergoes rigorous testing for permeability, peel strength, and hydraulic conductivity before leaving our facility.
