High Density Polyethylene (HDPE) Geomembranes

Geomembranes are synthetic membrane liners or barriers used to control fluid migration in a manmade project, structure, or system. They are made from relatively thin continuous polymeric sheets that are sometimes made from the infusion of geotextiles with asphalt, elastomer, or polymer sprays.High-Density Polyethylene geomembranes are designed to protect structures from the ingress of moisture, water, liquids, radon, carbon dioxide and methane together with chemicals. Our technical team can advise on product selection appropriate to the application and full installation method statements.

HDPE membrane is also known as high density polyethylene membrane, HDPE geomembrane, HDPE seepage control membrane, HDPE membrane is a plastic web made up of HDPE, whose HDPE is a highly crystalline, non-sexual thermoplastic resin. The appearance of the original state HDPE is milky white, in the micro-thin cross-section of a certain degree of translucency.HDPE geomembrane has a good resistance to environmental stress cracking performance, low temperature, aging resistance, corrosion resistance, to a larger range of use temperature (-60 - +60) and a longer service life of 50 years, widely used in the domestic garbage landfill impermeable, solid waste landfill impermeable, wastewater treatment plant impermeable, the Artificial lake seepage control, tailings treatment and other seepage control projects.

Properties of HDPE geomembrane

HDPE geomembrane is made of high-density polyethylene, which has excellent physical and mechanical properties and chemical stability. It has the following properties,Anti-seepage performance HDPE geomembrane can effectively prevent the infiltration of water and chemical substances in the soil and protect the stability of the soil body.High strength and toughness HDPE geomembrane has high tensile strength and elongation at break, which can resist the deformation of the soil body and the role of external loads.

Chemical resistance HDPE geomembrane has good chemical resistance in a variety of media such as acids, alkalis, salts and organic solvents.

What are the main preparation processes of HDPE geomembrane?

The main preparation process of HDPE geomembrane includes extrusion method, calendering method, blown film method and so on. Among them, extrusion method is a common and mature preparation process, which can realize high quality geomembrane production.

HDPE geomembrane how to carry out construction site quality control

During the construction of HDPE geomembrane, quality control is required to ensure the quality of the project. Commonly used quality control measures include material acceptance, construction process monitoring, and quality inspection of welded joints. At the same time, it is also necessary to pay attention to the environmental conditions and construction operation requirements, in order to avoid operational errors during the construction process and the impact of environmental factors on the quality of geomembrane.
