The needle-punching process uses barbed needles to repeatedly pierce through the upper and lower woven fabric and geotextile layers and the bentonite core. This mechanically intertwines the materials, bonding the three layers into a single, cohesive unit. It is far stronger than just surface adhesion.

Among the numerous geosynthetics on the market, many are made from high molecular polymer materials, which have a significant advantage in terms of cost-performance. However, if the raw materials used are of poor quality, the products after molding are also difficult to be used for a long time. For geomembranes, there are significant differences in physical and chemical properties between new HDPE granules and recycled HDPE granules...

Filtration refers to the function of geosynthetics that allows liquids (like water) within the soil to pass through and be discharged, while preventing the loss of upstream soil particles (see Figure a). The function is similar to that of a traditional sand filter layer...

In the geosynthetic materials market, geotextile is a common material. The production process of geotextile is mainly divided into woven geotextile and nonwoven geotextile, and further divided into weaving, needle-punched, hot-melt bonding, etc. depending on the specific processing details. These geotextiles are suitable for different scenarios. However, if universality and versatility are taken as a reference, nonwoven needle-punched geotextile is a product that has been market-tested, with mature technology, affordable price and durability.

In the industry, geogrids are made of various materials, such as glass fiber or steel-plastic. As a manufacturer of geosynthetic materials based on high molecular polymer, Zhonglong focuses on providing plastic geogrids that meet the national standard (GB/T 17689-2008), mainly divided into two types of raw materials: PP and PE.

A tailings storage facility (TSF) is a dedicated dam structure used to store tailings — the fine waste residues produced after mineral processing, which still contain trace useful components. It is not a simple dumping site. It is a complex and high-risk engineered system composed of a retaining dam, reservoir area, and drainage & seepage-control systems.
