sao tome and principe Adjustable 2.0mm Single Sided Textured Harmless HDPE Geomembrane

Geomembranes use plastic movies as anti-seepage substrates, commonly which encompass polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt combo geomembrane) is moreover designed and used.

Product Description

Introduction

Anti seepage Geomembrane is a waterproof material used in civil engineering, usually made of synthetic materials such as high-density polyethylene (HDPE), polypropylene (PP), or polyvinyl chloride (PVC). Therefore, anti-seepage geotextile membranes are widely used in civil engineering such as roads, tunnels, dams, embankments, and landfills, providing reliable anti-seepage protection for engineering projects.

Applications

High waterproof performance: Due to its high density, the anti-seepage geotextile film has a good waterproof effect, which can effectively isolate water, prevent groundwater infiltration and soil liquid leakage.

Corrosion resistance: The anti-seepage geotextile film has excellent chemical corrosion resistance and can resist the erosion of corrosive substances such as acid, alkali, and chemical agents.

Aging resistance: The specially treated anti-seepage geotextile film has good aging resistance and can be used in outdoor environments for a long time without being affected by UV rays, oxidation, thermal deformation, etc.

Impermeability: The anti-seepage geotextile membrane has a high thickness and tight structure, outstanding impermeability, and can effectively prevent the intrusion of groundwater.

Flexibility and plasticity: The anti-seepage geotextile membrane has a certain degree of flexibility and plasticity, which can adapt to the needs of different shapes and surfaces, and is easy to construct.

Environmental friendliness: Modern anti-seepage geotextile membranes are non-toxic and odorless during production and use, meeting environmental protection requirements.
