Textured HDPE geomembrane is a new type of impermeable material made from high-density polyethylene, featuring a high impermeability coefficient (up to the order of 1×10⁻¹³ cm/s) and excellent chemical stability. It can maintain a service life of 30 years in environments ranging from -60°C to 60°C. Its surface has a unique columnar point structure that increases the friction coefficient, making it suitable for slope projects such as dams and landfills. During construction, it is important to protect the geomembrane from direct impact from stones and to provide an appropriate protective layer to prevent UV exposure and thermal deformation. The raw materials meet environmental standards and do not pollute soil or water, but care must be taken during construction to avoid direct stone impact and thermal deformation.
