Assessing numerous geomembranes for your next geosynthetic application? Don’t ignore HDPE (HDPE) geomembrane. HDPE has been in use for decades and over this span a several researches have been performed to test its lifespan and capability to meet environmental sustainability project standards. Here, we investigate some of those studies to examine the pros of HDPE in comparison with other membrane types such as polyvinyl chloride.
How Does HDPE Compare With PVC and Other Geomembrane Types?
As a water-resistant barrier, a HDPE liner is favored over other options for its modest economic and functional advantage. Financially, HDPE membrane is superior thanks to its fairly uncomplicated fabrication, which has boosted supply and kept prices low in relation to other kinds of geomembranes. As more project designers become familiar with the substance, growing competence in its use further supports its market edge and economic edge over competing products.
Secondly, High-Density Polyethylene is chosen for its physical properties. Although examinations conducted on Polyvinyl Chloride and High-Density Polyethylene demonstrate a few practical discrepancies, High-Density Polyethylene often does surpass Polyvinyl Chloride and other geosynthetics in areas such as resistance to bending wear and kinetic force. Additionally, the material is a highly stable polyolefin that is inert and able to sustain long-term stability and durability. These properties position the HDPE geosynthetic liner a common option to impermeabilize and insulate refuse areas and other containment systems.
High-Density Polyethylene geosynthetic liner is also fabricated with supplements to enhance certain characteristics.
In what ways does the High-Density Polyethylene Geomembrane Support Environmental Environmental Health?
In comparison with other geomembranes, HDPE features the highest estimated unexposed longevity at >100 years. This extended lifespan makes High-Density Polyethylene a powerful tool for environmental conservation measures such as the reliable closing of a refuse area.
When it comes to exposed liner , a single study, an HDPE geomembrane enduring a decade of sunlight and wastewater showed no significant change in physical characteristics (e.g., tensile strength, tear resistance, puncture resistance, and carbon black content). The sole observed variation was in tensile elongation and melting index , both believed to be a result of material cross-linking as a result of 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 environmental durability . Moreover, it implies that current HDPE is expected to achieve higher performance due to technological enhancements in resin stabilization and manufacturing processes.
