Comparing various geomembranes for your geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been in use for decades and during that time several research has been conducted to check its longevity and ability in order to meet environmental sustainability project requirements. Here, we explore some of those studies to check the benefits of HDPE in comparison with other geomembranes types such as polyvinyl chloride (PVC).

How Does HDPE Equate to PVC as well as other Geomembrane Types?

Like 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, containing driven up supply and kept prices low in contrast to other forms of geomembranes. As more design engineers understand 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 tend to outperform PVC along with other geomembranes in areas including capacity folding damage and dynamic impact. Furthermore, the fabric is a very stable polyolefin that is certainly chemically inert and capable to maintain long-term integrity and durability. These properties increase the risk for HDPE geomembrane a popular option to waterproof and seal landfills along with other containment applications.

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

How Does the HDPE Geomembrane Help with 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 robust tool for environmental sustainability efforts including the safe closure of your landfill.

In the matter of exposed liner, one study, a HDPE geomembrane confronted with A decade of ultraviolet radiation and wastewater showed no significant change in physical properties (e.g., tensile, tear, puncture, and carbon black). The one observed difference what food was in tensile elongation and melt index, both believed to be a consequence of material cross-linking because of UV exposure. However, sunlight exposure over the 10-year period did little to impact a lot of the material’s properties insomuch it’s nearly indistinguishable from a newly manufactured sample.

The analysis demonstrates the capable role of HDPE geomembrane in environmental sustainability. Furthermore, it suggests that today’s HDPE to expect to perform at the more impressive range due to technological improvements in resin stabilization and sheet manufacturing techniques.
