Product Advantages
Exceptional Waterproofing: Haoyang's GCL utilizes bentonite clay, known for its superb water retention properties, forming a natural and effective barrier that prevents liquid migration.
Multi-layer Composite Design: Our GCL features a multi-layer composite structure, combining needle-punched nonwoven geotextiles and bentonite clay to enhance both durability and impermeability.
Self-Sealing Ability: The bentonite clay swells when exposed to water, automatically sealing any punctures or small holes, adding extra protection.
High Tensile Strength: With a tensile strength of ≥700, our GCL provides robustness and stability for long-term use in challenging environments.
Environmental Safety: As an eco-friendly material, GCL is a sustainable solution for waste management, minimizing environmental impact.
Applications
Haoyang’s Geosynthetic Clay Liner (GCL) is ideal for a range of waste containment and environmental protection applications, including:
Domestic waste landfills: Preventing leakage of hazardous waste liquids into the surrounding soil and groundwater.
Wastewater treatment plants: Lining basins, ponds, and lagoons to prevent contamination.
Mining and industrial waste: Serving as a secure barrier for industrial waste storage and tailing ponds.
Environmental remediation: Acting as a protective barrier for soil remediation projects.

Application Example
The following is an application example of sodium-based bentonite in a domestic waste landfill project:
The first phase of the Jingbian County Urban Domestic Waste Landfill covers an area of 62,476 square meters (approximately 93.7 acres), with a storage capacity of 104.0 cubic meters, an effective storage capacity of 1.029 million cubic meters, a landfill capacity of 300 tons per day, and a design service life of 10 years. The landfill adopts sanitary landfill technology to improve the environmental conditions of the original waste dumping site, making the residential area beautiful and clean, saving a lot of land, and improving the space utilization factor. At the same time, the project adopts artificial horizontal seepage prevention, and the seepage prevention project at the bottom of the reservoir area adopts a composite lining seepage prevention system, using polyester filament spunbond needle punched geotextile layer + HDPE artificial seepage prevention layer + GCL bentonite waterproof blanket + composite drainage network + compacted soil for seepage prevention, which can avoid the pollution of leachate to the surrounding surface water, groundwater, and soil, reduce the damage to human health, save pollution control costs, reduce economic losses caused by pollution, and improve residents' satisfaction level, with good environmental and economic benefits. The project covers an area of approximately 60,000 square meters, and the seepage prevention project in the reservoir area is constructed by our company, using a composite lining layer. The leachate is guided and collected by the three-dimensional composite drainage network produced by our company, effectively avoiding the pollution of surface water, groundwater, and soil.
In this project, the role of sodium-based bentonite waterproof blanket is to prevent sharp objects from damaging the membrane, effectively avoiding the harm of uneven settlement to the HDPE geomembrane. As an auxiliary seepage prevention layer, it does not pollute groundwater on the one hand, and on the other hand, it can prevent the backflow of groundwater.
To protect your property and environment, it is crucial to choose an efficient and environmentally friendly waterproof material. As a high-quality waterproof material, bentonite waterproof blanket can meet your various needs and create a safe and comfortable living environment for you. If you are looking for a reliable waterproof solution, please don't hesitate to choose bentonite waterproof blanket!
