Evaluating numerous geosynthetic membranes for your next geotechnical project? Don’t ignore high-density polyethylene (HDPE) geomembrane. HDPE has been in use for decades and during that time a number of studies have been carried out to evaluate its durability and ability to fulfill green project requirements. Here, we investigate some of those researches to understand the pros of HDPE compared with other geomembranes such as PVC.
How Does HDPE Stack Up With PVC and Other Geosynthetic Liners?
As a waterproofing liner, a HDPE liner is chosen over other materials for its reasonable economic and practical benefit. Financially, HDPE liner is better thanks to its fairly straightforward manufacturing process, which has driven up production and kept expenses down in contrast to other types of geosynthetic liners. As more project designers become comfortable with the substance, growing proficiency in its application further encourages its market edge and cost-effective advantage over competing products.
Next, HDPE is chosen for its physical attributes. Even though analyses performed on PVC and HDPE reveal very few practical differences, High-Density Polyethylene generally outclass PVC and other geosynthetics in spheres such as resistance to creases and shock. Furthermore, the polymer is a remarkably stable polymeric material that is inert and capable of sustain long-term integrity and durability. These properties render the HDPE geomembrane a preferred option to waterproof and secure waste disposal sites and other sealing applications.
High-Density Polyethylene geosynthetic liner can also be manufactured with enhancers to boost certain attributes.
How Does the HDPE Membrane Material Enhance Environmental Conservation?
Relative to other membrane materials, HDPE possesses the highest projected unexposed lifespan at >100 years. This high service life potential makes HDPE a powerful tool for environmental sustainability efforts such as the secure closure of a refuse area.
When it comes to exposed lining, a single study, an HDPE geomembrane enduring a decade of sunlight and wastewater showed no significant change in material properties (e.g., tensile, tear, puncture, and carbon black ). The only noticeable difference appeared in tensile elongation and melting index , both thought to result from cross-linking of the material due to 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 study demonstrates the capable 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 .
