Comparing various geomembranes for your geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been around use for many years and in that point many research has been conducted to try its longevity and ability to meet environmental sustainability project requirements. Here, we explore one particular studies to analyze some great benefits of HDPE in contrast to other geomembranes types like polyvinyl chloride (PVC).

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

As being a waterproofing liner, a HDPE geomembrane is favored over many other materials for its modest economic and operational advantage. Economically, HDPE geomembrane is superior as a result of its relatively straightforward manufacturing process, that has driven up supply and kept prices reduced contrast to other sorts of geomembranes. As more 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 because of its physical properties. While tests operate on PVC and HDPE show hardly any practical differences, HDPE does usually outperform PVC and other geomembranes in areas like capacity folding damage and dynamic impact. Furthermore, the information is certainly a stable polyolefin which is chemically inert and capable to maintain long-term integrity and durability. These properties make HDPE geomembrane a well known option to waterproof and seal landfills and also other containment applications.

HDPE geomembrane may also be manufactured with additives to amplify certain qualities.

So how exactly does the HDPE Geomembrane Help with Environmental Sustainability?

In contrast to other geomembranes, HDPE gets the highest theoretical unexposed service life at >100 years. This high service life potential makes HDPE an effective tool for environmental sustainability efforts like the safe closure of an landfill.

Regarding exposed liner, one study, a HDPE geomembrane encountered with Decade of ultraviolet radiation and wastewater showed no significant alternation in physical properties (e.g., tensile, tear, puncture, and carbon black). The only observed difference was at tensile elongation and melt index, both considered to be a direct result material cross-linking due to UV exposure. However, sunlight exposure over the 10-year period did little to impact almost all of the material’s properties insomuch it had become nearly indistinguishable coming from a newly manufactured sample.
