4800g Sodium Bentonite Geosynthetic Clay Liner(GCL)
A geosynthetic clay liner (GCL) is a type of barrier material used in construction and environmental engineering for containment applications, such as waterproofing. It is composite materials comprising bentonite clay sandwiched between layers of geotextiles. This unique combination results in a versatile and highly effective barrier against water infiltration.
Sodium bentonite Geosynthetic clay liner(GCL) usually include three layers, one side is flat fiber woven geotextile, the other side is nonwoven gofabrics, and in the middle is sodium bentonite, this kind of structure can enhance its performance and prevent the migration of the clay.
Haoyang Environmental Co., Ltd. is a pioneering force in environmental solutions since 2008. At Haoyang, we're committed to revolutionizing geosynthetic materials for a sustainable future. Today, we proudly present our flagship product: the 4800g sodium bentonite Geosynthetic Clay Liner (GCL), engineered to redefine waterproofing standards.

Applications of Sodium Bentonite Geosynthetic Clay Liner(GCL)
GCLs with sodium bentonite are wildely used in the following area:
◢ Landfills:
GCLs are commonly used in landfill liners and caps to prevent the leachate (liquid that has percolated through a landfill) from contaminating underlying soil and groundwater.
Geosynthetic clay liners serve as a barrier to control the migration of harmful substances, such as heavy metals and organic compounds, from the landfill waste into the surrounding environment.
◢ Waterproofing:
GCLs are also used in waterproofing applications for structures such as dams, canals, and reservoirs.
They act as a barrier to prevent water seepage, protecting structures from potential damage caused by water infiltration.
◢ Road and Rail Construction:
GCLs can be used in road and rail construction to provide slope stabilization and erosion control.
They help prevent soil erosion and water infiltration, maintaining the stability of embankments and cut slopes.
◢ Pond and Canal Liners:
GCLs are used in the construction of pond and canal liners to prevent water seepage and enhance water retention.
◢ Tunnel Construction:
GCLs can be applied in tunnel construction to provide waterproofing and prevent water ingress into tunnels.
Advantages of GCL
◢ Cost-Control
GCLs can offer cost savings compared to traditional clay liners in terms of material costs, transportation, and installation. Their ease of installation and versatility contribute to their cost-effectiveness.
◢ Long-Term Performance
When properly installed and maintained, GCLs can provide long-term performance. The self-sealing properties and durability of the sodium bentonite contribute to the effectiveness and longevity of the liner in various applications.
◢ Self-Sealing Properties
The sodium bentonite in GCLs has self-sealing properties. If the liner is punctured, the bentonite swells to fill and seal the puncture, helping to maintain the integrity of the liner over time.
◢ High Swelling Capacity
Sodium bentonite in GCLs has a high swelling capacity when hydrated, providing an additional layer of protection against water migration. This swelling property enhances the overall performance of the liner in terms of impermeability.
◢ Ease of Installation
GCLs are relatively easy to install compared to traditional clay liners. They come in large rolls or panels, making them convenient for transportation and installation. This can result in cost savings and faster construction times.
