Some basics of choosing HDPE geomembrane

HDPE geomembrane, commonly known as geomembrane or impermeable membrane, HDPE means high-density polyethylene and is a white granular product. It has a density of 0.941 to 0.960 g/cm, is non-toxic, odorless, and has high hardness. Its tensile strength and creep properties are better than those of low-density polyethylene (LDPE). It is also wear-resistant, flexible, resistant to high and low temperatures, chemically stable, insoluble in organic solvents, and resistant to acids, alkalis, and various salts. 

So HDPE geomembrane has the characteristics of high-density polyethylene, non-toxic, tasteless, high and low-temperature resistance, high strength, good hardness, good toughness, wear resistance, good chemical stability, acid and alkali resistance, and good impermeability, it is widely used in aquaculture as well as the planting of impermeable. It can also be used in animal husbandries, such as ground impermeability of pig farms, oxidation pond impermeability, and black film digester construction. 

Also, HDPE geomembrane can be involved in the construction of hydraulic engineerings, such as reservoirs, canals, rivers, cisterns, and environmental protection projects such as oil tank bottom seepage control, chemical plant seepage control, sewage treatment seepage control, tailings storage, fly ash landfill, landfill seepage control, etc. But do you know how to choose a good HDPE geomembrane?

Some basics of choosing HDPE geomembrane

HDPE geomembrane products are typical product materials in the geomaterials market and are used in many engineering projects for laying. Our company has the skills to use HDPE geomembranes in all aspects, so how should the purchase of HDPE geomembranes be carried out? The surface of the HDPE geomembrane is relatively smooth. When choosing the thickness of the HDPE geomembrane, the following factors can be considered. The first point to consider is the water pressure of the scenario where the HDPE geomembrane is being applied, and the strength distribution of the impermeable geomembrane joint material. 

The second point we have to consider is the way the contact surface is treated. When you want to use HDPE geomembrane for landfill, you need to carefully consider the contact area between the HDPE geomembrane and the site to avoid leakage. The third point to consider is the expected effect of HDPE geomembrane waterproofing. Not only that but also to carefully understand the technical parameters of the HDPE geomembrane purchased. Geomembranes are selected based on thickness and production process standards, with a thickness generally ranging from 0.1mm-3.0mm and process standards divided into four standards: non-standard, national standard, new material, and American standard.

How to use HDPE geomembrane correctly?

If the thickness of the chosen HDPE geomembrane is thin, care should be taken not to let it be pierced by sharp objects on-site during construction. Of course, a layer of geotextile can be laminated on one or both sides of the geomembrane, which not only can protect the geotextile well but also can play a role in increasing the friction. Since the demand for HDPE geomembranes is increasing, the relevant departments have also introduced relevant standards and testing methods one after another to make the industry more standardized and regulated.
