Comparing various geomembranes for your next geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been around use for many years and throughout the period several research has been conducted to try its longevity and talent to meet environmental sustainability project requirements. Here, we explore some of the people studies to look at some great benefits of HDPE in contrast to other geomembranes types such as polyvinyl chloride (PVC).

How Does HDPE Match up against PVC as well as other Geomembrane Types?

As 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, containing driven up supply and kept prices reduced contrast with other forms of geomembranes. As increasing numbers of design engineers familiarize yourself with the pad, growing competence in their use further promotes its market dominance and economic edge over competing products.

Secondly, HDPE may be favored because of its physical properties. While tests run using PVC and HDPE show few practical differences, HDPE does tend to outperform PVC and also other geomembranes in areas such as effectiveness against folding damage and dynamic impact. Furthermore, the information is a very stable polyolefin that is certainly chemically inert and capable to maintain long-term integrity and sturdiness. These properties increase the risk for HDPE geomembrane a popular option to waterproof and seal landfills and other containment applications.

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

What makes the HDPE Geomembrane Bring about Environmental Sustainability?

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

In the case of exposed liner, one study, a HDPE geomembrane subjected to Ten years 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 consequence of material cross-linking as a result of UV exposure. However, sunlight exposure on the 10-year period did little to affect most of the material’s properties insomuch it’s nearly indistinguishable from your newly manufactured sample.
