This high performance GCL liner is designed for environmental protection applications such as chemical storage yards and oil depots. It provides a reliable barrier against hazardous liquid leakage, protecting soil and groundwater.
The core material is sodium bentonite, which swells upon contact with moisture to create a highly impermeable layer. The surrounding geotextile layers ensure structural stability and prevent material displacement.
Its excellent chemical resistance and sealing performance make it suitable for projects where environmental safety is a priority.
