Comparing various geomembranes for your next geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been around use for several years and in that period many research has been conducted to try its longevity and ability to meet environmental sustainability project requirements. Here, we explore one particular studies to look at the main advantages of HDPE weighed against other geomembranes types like polyvinyl chloride (PVC).

What makes HDPE Compare With PVC as well as other Geomembrane Types?

As a waterproofing liner, a HDPE geomembrane is favored over other materials for its modest economic and operational advantage. Economically, HDPE geomembrane is superior thanks to its relatively straightforward manufacturing process, containing driven up supply and kept prices low in contrast with other sorts of geomembranes. Weight loss design engineers know more about the pad, growing competence in the use further promotes its market dominance and economic edge over competing products.

Secondly, HDPE has been favored due to the physical properties. While tests are powered by PVC and HDPE show very few practical differences, HDPE does often outperform PVC along with other geomembranes in areas for example effectiveness against folding damage and dynamic impact. Furthermore, the fabric is an extremely stable polyolefin that’s chemically inert and capable to maintain long-term integrity and sturdiness. These properties increase the risk for HDPE geomembrane a favorite replacement for waterproof and seal landfills and also other containment applications.

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

How can the HDPE Geomembrane Help with Environmental Sustainability?

In contrast to 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 like the safe closure of an landfill.

Regarding exposed liner, one study, a HDPE geomembrane subjected to Ten years of ultraviolet radiation and wastewater showed no significant change in physical properties (e.g., tensile, tear, puncture, and carbon black). The one observed difference was at tensile elongation and melt index, both regarded as a direct result material cross-linking because of UV exposure. However, sunlight exposure in the 10-year period did little to affect almost all of the material’s properties insomuch that it was nearly indistinguishable coming from a newly manufactured sample.
