1, Impermeability: GCLs provide excellent impermeability due to the swelling nature of sodium bentonite, forming a tight waterproof barrier when in contact with water.
2, Sealing Capability: The ability of GCLs to swell and form a colloidal waterproof layer enhances their sealing capability, preventing water from permeating through the liner.
3, Flexibility: GCLs are flexible and conform to the contours of the underlying surface, making them suitable for different shapes and profiles in various construction projects.
4, Chemical Resistance: GCLs exhibit resistance to a wide range of chemicals, making them suitable for applications in environments with different types of contaminants.
5, Ease of Installation: The installation process of GCLs is relatively simple compared to traditional clay liners. This can result in cost savings and faster project completion.
