As what you can tell as per the above information, 120 mil HDPE geomembrane is a type of anti seepage geomembrane made of HDPE materials in the thickness of 3mm. “mil” is a commonly recognized unit for representing the membrane’s thickness while 1 mil estimately equals to 0.0254 mm. For many 120 mil gemembrane manufacturers and wholesalers, HDPE is a preferred material with great chemical resistance, anti UV ability as well as mechanical strength. Going with its thickness of 120 mil, this geomembrane can bear the harsh environment of landfills and mining projects.
The Core Performance Advantages of 120 mil HDPE Geomembranes
Better Acupuncture and Tearing Resistance Ability
The thickness of 120 mil HDPE geomembrane offers a reliable protecting layer between the anti seepage system and harsh constructing conditions like sharp stones, construction wastes and heavy-duty equipments. Compared with 60 mil HDPE geomembrane or 80 mil geomembrane, 120mil HDPE geomembranes can bear the external damage and strikes more effectively.
Strong UV and Harsh Weather Resistance
You can definitey take the advantage of 120 mil HDPE geomembrane’s stronger harsh weather resistant ability when your projects are handled under the conditions of long-time exposure in the sunlight or harsh weather. At the same time, its great UV resistant ability can extend the geomembrane’s lifespan and stablize its anti seepage effect when being applied in a temporary storage pool of mining project or the bare ground of landfills.
Good Chemical Stablity
This HDPE membrane can go against the acid solution and trash leachate corrosion that may happen during the process of mining operation. In a word, 120 mil HDPE geomembranes can effectively avoid the erosion from harmful substances(i.e. chemicals, solution, heavy metal, etc.) and do good to the environmental protection.
Lower Permeability
Thanks to the lower permeability of 120 mil HDPE geomembrane, the protection of underground water resource and pollution control can enormously be guaranteed. What’s more, the stable sealing effect can be realized when the membrane is appied in the tailing mining prjojects.
Why Can You Use 120mil or 3.0 mm HDPE Geomembrane in Landfills?
The security of anti seepage system plays an important role in reducing the risk of nearby environmental pullution during the whole period of landfill projects. Yes, it really matters! However, 120 mil or 3mm HDPE may be a optimized solution to this concern:
- Bottom Anti Seepage Layer: To prevent the leachate from penetrating the underground water.
- Capping System: Stop the rain water from penertration, which can refrain the flow of leachate.
- Great Loading Capacity: Can bear the big pressure from solid waste.
- Durable for Use: The lifespan of these HDPE geomembranes can last over 50 years under proper installation.
Moreover, the thickness of 3.0 mm or 120 mil can be much easier to recognize by environmental protection regulatory agencies. This type of geomembranes can also help your projects comply with the operating standards of local government.
Why This 120mil or 3mm HDPE Geomembrane Performs Best in the Mining Project?
As for the mining operation projects, this HDPE geomembranes are widely used in tailings, waster water pools and heap leaching pools. Their strengths are mainly reflected as follows:
- Heap Leaching Pool/Pond Liners: Effectively prevent the leakage of acid solution from polluting the underground water.
- Tailing Dam Liners: Capable of withstanding the high pressure of water and mud.
- Reinforced Chemical Resistance: Can handle the erosion caused by heavy metal and aggressive solvents existing in the mining waste.
Even in high altitude, remote or complicated geology areas, the 120 mil HDPE Geomembrane produced by Xinyu Geosynthetics can keep an intacted structure and run smoothly in a long term for any mining projects.
Installation Tips of These 120 mil HDPE Geomembranes
Although 120 mil or 3.0 mm HDPE Geomembranes perform well enough in landfill or mining projects, however, you should pay much attention to the following installation tips:
- Use Professional Equipment: Consider the thickness and weight of 120 mil HDPE geomembranes, professional welding machines(i.e. hot wedge welders or extrusion welders) are necessary to use for installing them.
- Need an Experienced Engineering Team: The complexity of welding thick membranes asks for skillful engineering workers to handle the installation job.
- Quality Inspection: To ensure a perfect welding line, a vacuum box testing and air pressure testing are highly recommended to be done.
Even if the installing process is a little more complicated than that of HDPE geomembranes in other thickness type, nevertheless, the investment you spend on these membranes will be neutralized because of their advantages of low-frequency maintenance and lower error ratio.
Cost vs Long-term Value
The unit price of 120 mil HDPE geomembrane is comparatively higher than 60 mil HDPE geomembrane and 80 mil HDPE geomembrane. However, this type of geomembrane is a more reasonable selection in the long run with the perspective of lower maintenance cost and environmental protection.
Thickness | Avg. Cost Per m² | Typical Lifespan | Risk of Early Failure |
60 mil | Low | 10–20 Yrs. | High |
100 mil | Moderate | 25-35 Yrs. | Medium |
120 mil | Higher | 40-50 yrs. or More | Very Low |
Taking a copper ores project of Xinyu Geosynthetics in Chile for example: Xinyu’s engineering team installed more than 2,000,000 ㎡ of 120 mil HDPE geomembranes as liners of heap leach facilities. As a result, all the geomembranes they bought from us are still in the running process. No leakage occurs until now even under harsh environmental conditions, such as the pH exposure and heavy traffic from machinery. You can tell that thicker geomembranes are more popular with worldwide project contractors and owners.
Conclusion
The whole system’s security and regulatory compliance of any industrial projects rely on the quality of geomembranes for anti seepage use. In this article, you must have learned why this 120 mil HDPE Geomembrane is your primary anti seepage materials that can be applied in landfill or mining projects.
To conclude, 120 mil HDPE geomembrane is the most reliable anti seepage solution to your landfill and mining projects by taking advantages of its quality and sustainability. It can perform quite well with the appearance of pond liners or dam liners in different landfills and tailing dams(minings).
