8m Wide 0.75mm HDPE Geomembrane

Introduction to Geomembrane

     An 8-meter-wide 0.75mm HDPE geomembrane is made from 100% high-quality virgin polyethylene resin, processed by advanced techniques. The main components consist of 97.5% high-density polyethylene, along with approximately 2.5% carbon black and trace amounts of anti-oxidant, heat-stabilizer and other additives. There are no fillers or expanders. Its thickness is 0.75mm and the width is 8 meters. This product has strong anti-seepage properties, effectively preventing liquid penetration; it possesses UV resistance, acid and alkali resistance, and can be used stably outdoors; it has good flexibility, facilitating construction and laying, and is suitable for various fields such as water conservancy, environmental protection, and aquaculture for anti-seepage projects.

Application fields of Geomembrane

I. Water Conservancy Engineering Field

(1) Anti-seepage of Small Reservoirs

In a small mountainous reservoir project, an 8m Wide 0.75mm HDPE Geomembrane was used as the anti-seepage layer. Its 0.75mm thickness ensured the anti-seepage effect while having good flexibility, which could fit the complex base of the reservoir. The 8-meter width reduced the splicing workload and lowered the leakage risk. After use, the leakage volume of the reservoir significantly decreased, effectively improving the water storage capacity and ensuring the irrigation water supply for surrounding farmlands.

(2) Anti-leakage of Irrigation ChannelsIn a large-scale agricultural irrigation channel renovation project, this geotextile membrane was selected. It effectively prevented the leakage of irrigation water and improved the utilization rate of water resources. Due to its strong chemical stability, it could resist the erosion of irrigation water and chemical substances in the soil, and could work stably for a long time, ensuring the efficient operation of the irrigation system and helping to increase agricultural production.

II. Environmental Engineering Scope

(1) Liner of Landfill Sites

A newly-built small landfill site adopted this type of geotextile membrane as the bottom liner. The anti-seepage and corrosion resistance of the HDPE material prevented the leakage of landfill waste and contaminated soil and groundwater. The 8-meter width adaptation to the large-scale laying requirements of the landfill site reduced the joint processing cost and leakage risks, and built a defense line for the safe landfill of waste.

(2) Anti-seepage of Sewage Treatment Ponds

In a township sewage treatment plant, an 8m Wide 0.75mm HDPE Geomembrane was used for the treatment pond anti-seepage. It isolated the sewage from the contact with the soil around the pond, preventing the leakage of sewage and pollution of the environment. The durability of the material could withstand the complex chemical environment of the sewage, reducing the maintenance frequency of the sewage treatment facilities and ensuring the continuous and stable operation of the sewage treatment work.

III. Aquaculture Industry

(1) Fish Pond Construction

Many farmers chose this geotextile membrane when building new fish ponds. The 0.75mm thickness could both prevent seepage and retain water, and was convenient for construction operations. The 8-meter width could cover the bottom and slope of the fish pond extensively, reducing splicing gaps and maintaining good water quality of the fish pond, creating a stable environment for fish growth, and increasing the farming income.

(2) Shrimp Pond Protection

In the coastal shrimp farming area, 8m Wide 0.75mm HDPE Geomembrane was applied to the shrimp ponds. Its resistance to seawater corrosion effectively resisted seawater erosion, ensuring the stability of the shrimp pond structure. At the same time, the anti-seepage function maintained the constant water level of the shrimp pond, helping shrimp to grow healthily and increasing the yield and quality of shrimp farming.

IV. Mining Field Application

(1) Anti-seepage of Tailings Dams

A small non-ferrous metal mine's tailings dam adopted the 8m Wide 0.75mm HDPE Geomembrane for anti-seepage treatment. It effectively prevented the leakage of wastewater containing heavy metal ions from the tailings dam, avoiding contamination of the surrounding soil and water bodies. The 8-meter width was suitable for large-scale laying of the tailings dam, reducing construction difficulty and ensuring the environmental compliance of mining production.

(2) Anti-leakage of Heap Leaching Ponds

In the mining heap leaching process, the heap leaching ponds used this geotextile membrane. Its anti-seepage performance ensured that the leaching liquid did not leak, improving the metal leaching rate, and reducing resource waste. The high strength of the material could withstand the pressure of heap leaching materials, ensuring the smooth progress of the heap leaching operation and improving the economic and environmental benefits of mining production.

Product parameter specifications

Application Case of 0.75mm Geomembrane

1. Qatar Fish Pond: In August 2020, a customer in Qatar sought a solution for the frequent illness of fish in the natural fishpond and high operating costs. After communication, it was recommended to use 100% natural material, 0.75mm thick HDPE geotextile membrane. After providing samples of 0.5mm, 0.75mm, and 1.00mm and the third-party test report, the customer chose the 0.75mm product. Due to the inability of the engineer to provide on-site guidance due to the pandemic, the installation and welding were completed through online video. Compared to not using the geotextile membrane before, the water quality of the fishpond became stable after use, the incidence of fish diseases decreased significantly, and the operating costs decreased. 

2. Mongolia Mining Area: In a certain mining area in Mongolia, an 8m wide HDPE geotextile membrane with a thickness of 0.75mm was used for the anti-seepage of the chemical solution pool. This geotextile membrane has good flexibility and can adapt to the complex terrain and possible ground subsidence in the mining area. Compared with other thinner anti-seepage materials, its anti-puncture and chemical corrosion resistance are better, effectively preventing chemical solution leakage and avoiding pollution of the surrounding soil and water bodies, ensuring the environmental compliance of the mining area production, and having a lower cost than thicker specification products. 

3. American Landscape Lake: This specification geotextile membrane was used in the construction of a landscape lake in the United States. The 8-meter width reduces the amount of splicing work and lowers the risk of leakage. Compared with traditional clay anti-seepage materials, the 0.75mm HDPE geotextile membrane has better anti-seepage effect and can effectively maintain the water level of the landscape lake. It has strong weather resistance and can resist outdoor ultraviolet rays, temperature changes, etc., maintaining stable performance for a long time, providing a lasting and reliable anti-seepage guarantee for the landscape lake, and creating a beautiful and stable landscape water environment.

   
   

Future Outlook of 0.75mm Geomembrane

Globally, the prospects for 8m Wide 0.75mm HDPE Geomembrane are promising.

1. In the field of environmental protection, as countries pay increasing attention to pollution control, the demand for landfill sites and sewage treatment plants for this material will continue to rise, as it is used to prevent pollutant leakage. In the field of water conservancy projects, emerging countries are vigorously developing infrastructure, and the construction of irrigation channels, small reservoirs, etc. will be widely adopted to improve water resource utilization.

2. From a technological trend perspective, in the future, emphasis will be placed on enhancing material performance, such as improving resistance to ultraviolet rays and extending the outdoor service life. Through improvements in manufacturing processes, optimizing the uniformity of product thickness, and improving welding reliability. In the domestic market, with the promotion of the rural revitalization strategy, the construction of agricultural facilities has increased, and this geocomposite membrane will be continuously expanded in applications such as fish ponds, shrimp ponds, and agricultural water storage tanks. Moreover, with the acceleration of the standardization process, product quality and application specifications will be further improved, promoting its wider application.
