Assessing different geosynthetic membranes for your next environmental application? Don’t miss high-density polyethylene (HDPE) membrane. HDPE has been in use for years and during that time a several studies have been performed to test its longevity and capability to fulfill environmental sustainability project standards. Here, we delve into some of those researches to examine the pros of HDPE compared with other geosynthetic membranes such as vinyl.

How Does HDPE Stack Up With PVC and Other Geosynthetic Liners?

As a water-resistant membrane, a HDPE liner is chosen over other substances for its notable economic and functional advantage. Cost-wise, HDPE liner is better thanks to its comparatively uncomplicated fabrication, which has boosted supply and kept prices affordable in relation to other types of membranes. As more project designers become acquainted with the material, increasing proficiency in its use further encourages its market dominance and economic advantage over alternative options.

Secondly, High-Density Polyethylene has been favored for its material characteristics. Despite evaluations on PVC and High-Density Polyethylene reveal scant practical distinctions, High-Density Polyethylene often does exceed Polyvinyl Chloride and other membrane materials in spheres such as tolerance to folding damage and shock. Besides, the polymer is a exceptionally stable polymeric material that is inert and can preserve long-term cohesion and endurance. These characteristics make the High-Density Polyethylene geomembrane a preferred choice to waterproof and insulate waste disposal sites and other containment systems.

High-Density Polyethylene geomembrane can be manufactured with additives to boost certain attributes.

How Does the High-Density Polyethylene Membrane Material Aid in Environmental Environmental Health?

Compared with other geosynthetics, HDPE features the highest estimated unexposed longevity at greater than 100 years. This high service life potential renders High-Density Polyethylene a valuable asset for environmental sustainability efforts such as the safe closure of a refuse area.

When it comes to exposed liner , one study , an HDPE geomembrane subjected to ten years of sunlight and wastewater exhibited no substantial modification in physical properties (e.g., tensile strength, tear resistance, puncture resistance, and carbon black content). The sole observed variation appeared in tensile stretch and melt flow index, both assumed to be due to material cross-linking caused by UV exposure . Nonetheless, sunlight exposure over the 10-year period did little to impact most of the material’s properties insomuch that it was nearly indistinguishable from a newly manufactured sample .

The study highlights the proficient role of HDPE geomembrane in ecological sustainability. Moreover, it suggests that today’s HDPE can be expected to perform at a higher level thanks to technological improvements in resin stabilization and sheet manufacturing techniques .

Using HDPE Geomembranes as a Closure Solution
