Comparing various geomembranes for your upcoming geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been doing use for many years and throughout that time numerous studies have been conducted to test its longevity and ability to meet environmental sustainability project requirements. Here, we explore some of the people studies to look at the benefits of HDPE compared with other geomembranes types such as polyvinyl chloride (PVC).

How Does HDPE Look when compared with PVC and Other Geomembrane Types?
Being a waterproofing liner, a HDPE geomembrane is favored over many other materials because of its modest economic and operational advantage. Economically, HDPE geomembrane is superior thanks to its relatively straightforward manufacturing process, which has driven up supply and kept prices low in contrast with types of geomembranes. As more design engineers know more about the information, growing competence in the use further promotes its market dominance and economic edge over competing products.

Secondly, HDPE has been favored because of its physical properties. While tests are powered by PVC and HDPE show very few practical differences, HDPE does have a tendency to outperform PVC along with other geomembranes in areas for example resistance to folding damage and dynamic impact. Furthermore, the fabric is definitely a stable polyolefin that's chemically inert capable to maintain long-term integrity and sturdiness. These properties increase the risk for HDPE geomembrane a well known option to waterproof and seal landfills and also other containment applications.

HDPE geomembrane can even be manufactured with additives to amplify certain qualities.

So how exactly does the HDPE Geomembrane Contribute to Environmental Sustainability?
Compared with other geomembranes, HDPE has the highest theoretical unexposed service life at >100 years. This high service life potential makes HDPE an effective tool for environmental sustainability efforts such as the safe closure of the landfill.

In the matter of exposed liner, one study, a HDPE geomembrane subjected to Decade of ultraviolet radiation and wastewater showed no significant difference in physical properties (e.g., tensile, tear, puncture, and carbon black). The one observed difference is at tensile elongation and melt index, both thought to be a consequence of material cross-linking as a result of UV exposure. However, sunlight exposure on the 10-year period did little to impact almost all of the material’s properties insomuch it had become nearly indistinguishable from a newly manufactured sample.

Case study demonstrates the capable role of HDPE geomembrane in environmental sustainability. Furthermore, it shows that today’s HDPE can be expected to do with a advanced thanks to technological improvements in resin stabilization and sheet manufacturing techniques.
