Evaluating different geomembranes for your next geotechnical project? Don’t miss high-density polyethene (HDPE) geomembrane. HDPE has been in use for decades and over this span a several studies have been conducted to test its lifespan and capability to satisfy green project criteria. Here, we investigate some of those researches to examine the benefits of HDPE compared with other membrane types such as PVC.
How Does HDPE Compare With PVC and Other Geosynthetic Liners?
As a water-resistant barrier, a HDPE membrane is favored over other materials for its notable financial and functional advantage. Cost-wise, HDPE membrane is better thanks to its relatively uncomplicated production method, which has driven up supply and kept expenses affordable in contrast to other varieties of geosynthetic liners. As more project designers become familiar with the product, increasing competence in its implementation further supports its market dominance and cost-effective advantage over competing products.
Next, HDPE has been favored for its physical properties. While tests run on Polyvinyl Chloride and HDPE reveal minimal practical differences, High-Density Polyethylene does tend to exceed PVC and other membrane materials in areas such as withstanding creases and dynamic stress. Additionally, the polymer is a highly stable polymeric material that is non-reactive and has the capacity to maintain long-term soundness and durability. These attributes make the HDPE geosynthetic liner a popular option to make waterproof and close refuse areas and other enclosure uses.
High-Density Polyethylene geosynthetic liner may also be created with additives to enhance certain features.
What ways does the HDPE Membrane Material Enhance Environmental Sustainability?
In comparison with other membrane materials, High-Density Polyethylene possesses the highest estimated unexposed longevity at over 100 years. This prolonged service life makes HDPE a valuable asset for environmental eco-friendly practices such as the safe sealing of a dump site.
Concerning exposed lining, one study , a HDPE geomembrane exposed to 10 years of ultraviolet radiation and wastewater showed no significant change in physical properties (e.g., tensile, tear, puncture, and carbon black ). The only observed difference was in tensile elongation and melt index , both believed to be a result of material cross-linking caused by UV exposure . Nevertheless, a decade of sunlight exposure minimally affected the material’s properties, making it nearly the same as a new sample.
The study highlights the proficient role of HDPE geomembrane in ecological sustainability. Additionally, it implies that current HDPE is expected to achieve higher performance due to technological enhancements in resin stabilization and manufacturing processes.
