Assessing different membrane types for your next geosynthetic application? Don’t overlook HDPE (HDPE) membrane. HDPE has been in use for decades and during that time a number of studies have been conducted to evaluate its lifespan and capability to fulfill green project standards. Here, we investigate some of those studies to examine the pros of HDPE when compared with other membrane types such as PVC.
How Does HDPE Measure Up With PVC and Other Membrane Varieties?
As a waterproofing liner, a HDPE liner is preferred over other substances for its modest cost-effective and practical benefit. Financially, HDPE geomembrane is more advantageous thanks to its comparatively straightforward manufacturing process, which has boosted availability and kept expenses affordable in contrast to other varieties of membranes. As more design engineers become comfortable with the substance, growing proficiency in its use further encourages its market leadership and economic benefit over alternative options.
In addition, HDPE is chosen for its structural qualities. Even though analyses performed on PVC and High-Density Polyethylene indicate scant practical distinctions, HDPE generally surpass Polyvinyl Chloride and other geosynthetics in areas such as endurance against folding damage and kinetic force. Additionally, the polymer is a highly stable polymeric material that is chemically inert and can maintain long-term soundness and durability. These attributes position the HDPE geosynthetic liner a popular selection to impermeabilize and close waste disposal sites and other containment systems.
High-Density Polyethylene geomembrane is also fabricated with additives to boost certain attributes.
How Does the HDPE Geosynthetic Liner Contribute to Environmental Sustainability?
Relative to other geosynthetics, HDPE has the highest projected unexposed lifespan at more than a century. This long-term service capability establishes High-Density Polyethylene a valuable asset for environmental sustainability initiatives such as the safe sealing of a landfill.
In the case of uncovered liner , a study , an HDPE geomembrane subjected to a decade of sunlight and wastewater exhibited no substantial modification in physical characteristics (e.g., tensile strength, tear resistance, puncture resistance, and carbon black content). The only noticeable difference appeared in tensile stretch and melt flow index, both assumed to be due to material cross-linking as a result of UV exposure . Nevertheless, exposure to sunlight over the decade had minimal effect on most of the material’s properties, rendering it almost identical to a newly produced sample .
The research shows the effective role of HDPE geomembrane in environmental durability . Furthermore, it implies that current HDPE is expected to achieve higher performance due to technological enhancements in resin stabilization and manufacturing processes.
