Product Description

Special High-Strength Geomembrane For Tailings Ponds And Landfills


Product Introduction

    Smooth geomembrane is a kind of smooth surface geomembrane, which is mainly made of high polymer materials such as high density polyethylene (HDPE).


 Product Properties

1. Excellent chemical corrosion resistance: can resist the erosion of a variety of chemical substances, including acid, alkali, salt and so on.
2. Large temperature range: can be used in a wide temperature range, with good heat resistance and cold resistance.
3. Long service life: under proper use and maintenance conditions, the service life of smooth geomembrane can be very long.
4. High tensile strength: with high tensile strength and elongation, it can withstand certain water pressure and adapt to foundation deformation.
5. Good impermeability: The use of plastic film impermeability, effectively cut off the leakage channel, often used in waterproof and impermeability projects.


Product Application

1. The impermeable layer of the landfill.
2. Waterproof layer of tailings storage yard.
3. Water conservancy projects in the channel seepage prevention, dam seepage prevention.
4. Waterproofing measures in subway engineering.
5. Seepage prevention of artificial lakes, reservoirs and other water bodies.
