Examining The Advantages Of HDPE Geomembrane

Comparing various geomembranes for your forthcoming geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been use for decades and throughout that point several reports have been conducted to evaluate its longevity and talent to satisfy environmental sustainability project requirements. Here, we explore some of those studies to look at some great benefits of HDPE weighed against other geomembranes types including polyvinyl chloride (PVC).

So how exactly does HDPE Equate to PVC and also other Geomembrane Types?

Like a waterproofing liner, a HDPE geomembrane is favored over other materials due to the 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 lacking in contrast with other kinds of geomembranes. As increasing numbers of design engineers familiarize yourself with the material, growing competence rolling around in its use further promotes its market dominance and economic edge over competing products.

Secondly, HDPE has been favored for its physical properties. While tests run on PVC and HDPE show very few practical differences, HDPE does often outperform PVC and also other geomembranes in areas including effectiveness against folding damage and dynamic impact. Furthermore, the material is certainly a stable polyolefin which is chemically inert capable to maintain long-term integrity and sturdiness. These properties make HDPE geomembrane a well known option to waterproof and seal landfills and other containment applications.

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

How can the HDPE Geomembrane Give rise to Environmental Sustainability?

In comparison with other geomembranes, HDPE has got the highest theoretical unexposed service life at >100 years. This high service life potential makes HDPE an effective tool for environmental sustainability efforts including the safe closure of an landfill.

Regarding exposed liner, one study, a HDPE geomembrane encountered with A decade of ultraviolet radiation and wastewater showed no significant alteration of physical properties (e.g., tensile, tear, puncture, and carbon black). The only observed difference was in tensile elongation and melt index, both considered to be a direct result material cross-linking as a result of UV exposure. However, sunlight exposure within the 10-year period did little to impact most of the material’s properties insomuch it's nearly indistinguishable from your newly manufactured sample.
