Geomembrane Dam Liner

Geomembranes are made from impermeable geosynthetic material consisting of thin continuous sheets of polymers. Geomembranes create an impermeable barrier that prevents the leakage of harmful contaminants or dangerous chemicals to surrounding environments. It is also regularly used as containment barriers for potable water and irrigation storage requirements to prevent leakage. Geomembranes are used in conjunction with other geosynthetic products to control fluid movement and provide containment in projects related to mining, sewage treatment and canal construction.

 

 

The growing application of geomembranes is noticeable in different industries due to the versatility of the product. Geomembranes have a wide range of applications in industries such as mining, marine, civil, water treatment and transportation. Some of the applications are detailed below.

Textured or Smooth Geomembrane?

A textured product is necessary or not. This apparent truism must be remembered in many cases where a product is specified for a project that clearly does not qualify to be designated as textured but is designated as such, creating enormous confusion over the uncertainty of the customer's needs.

If the client does not clarify what he needs, it will be difficult to offer the appropriate solution under conditions comparable to those of any competing company.

2. Is a Geomembrane with a wider roll better?

There is a technical limit for manufacturing geomembranes. In high density polyethylene (HDPE), this is 7.5 to 8m. Beyond this limit, either the raw material is not an HDPE and is instead a softer material which enables the extrusion-header system of the machine to complete the geomembrane transformation cycle, or the uniform thickness or thermal treatment parameters of the raw material have been seriously compromised. Within these limits and exceeding a minimum width, under which it would be unreasonable to present a product for the Safe Containment application, the roll width is the choice of the manufacturer, usually subject to the presentation format and transport cost optimisation.

There is hardly any difference between the cost of machines for given widths.

Within these limits, it is true that a wider roll relieves installation costs in large projects by a small percentage; however it is always at the expense of a higher cost of handling bulk unit weight of the roll or overruns in the finishing of curves or corners.

3. Differences between LLDPE and HDPE?

Linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) are similar raw materials in terms of composition, but very different in their behavior, as already mentioned in previous sections.

HDPE has become a global standard for Secure Containment applications precisely because of its unique properties and marketing an LLDPE as HDPE in these applications is equivalent to offering a substitute product without any benefit to the customer. Differentiating them is very simple. It would be sufficient to require the MFI parameter. Below 1.2 for 190/5 kg it is an HDPE and above it is not. It's as simple as that.
