Alumina Red Mud Storage Facility Project in Indonesia
Project background:
Red mud is a mixture of waste residues and wastewater generated in the process of alumina production. It is called red mud because it is rich in iron oxide (ferrous oxide oxidizes to ferric oxide in open conditions), giving it a red color. Red mud is highly alkaline and contains aluminum ions as well as harmful substances such as fluorine and chromium. If not properly treated, it can cause environmental pollution to water and soil. Therefore, effective anti-seepage measures are essential for red mud storage facilities. Typically, dams are constructed at valley mouths or on flat terrain to intercept and contain red mud, creating storage capacity for its proper management.
The HDPE smooth geomembrane produced by our company has been selected for the Alumina Red Mud Storage Facility Project in Indonesia due to its stable quality and performance exceeding national standards. It has gained high recognition from customers in practical use.

Funtions of products in every layer:
1, HDPE Geomembrane:
Possesses corrosion resistance and anti-aging properties, effectively serving as a barrier against seepage and isolation.
2, Upper Layer Filament Spunbond Needle-punched Geofabric:
Provides permeability and anti-filtering functions while preventing the frictional force generated by sharp objects or uneven loads from damaging the membrane.
3, Lower Layer Filament Spunbond Needle-punched Geofabric:
Acts as a protective layer for the geomembrane, preventing damage from sharp objects in the underlying soil, especially under long-term loading conditions.
Specific Products We Use
1, 2mm HDPE geomembrane
A 2mm HDPE geomembrane is a geosynthetic liner made of high-density polyethylene (HDPE) material with a thickness of 2 millimeters. HDPE geomembranes are commonly used for waterproofing and seepage control in various engineering projects, including landfill sites, wastewater treatment plants, reservoirs, mining operations, and chemical facilities. In the Alumina Red Mud Storage Facility Project, the 2mm HDPE geomembrane plays a crucial role, offering the following key functions and advantages:
1, Seepage Prevention: The 2mm thick HDPE geomembrane serves as a reliable barrier, effectively preventing the penetration of harmful substances from alumina red mud into the surrounding soil and groundwater.
2, Isolation: The geomembrane isolates the red mud from the surrounding environment, preventing the diffusion of chemicals that could negatively impact the soil and water.
3, Stability: The 2mm thickness of the HDPE geomembrane provides sufficient physical strength and stability to withstand the pressure and loads within the structure of the red mud storage facility.
4, Corrosion Resistance: HDPE geomembranes exhibit excellent corrosion resistance, maintaining stability over the long term in environments containing chemical substances.
5, Durability: Due to its robustness and long lifespan, the 2mm HDPE geomembrane ensures the sustainability and long-term benefits of the Alumina Red Mud Storage Facility Project.
2，600g/m² filament spunbond needle-punched geofabric
600g/m² filament spunbond needle-punched geofabric is a geotextile fabric with a weight of 600 grams per square meter. It uses filament spunbond technology and is further reinforced through needle-punching. This type of geofabric is commonly used in engineering projects, and its primary functions in this project include:
1, Soil Reinforcement and Enhancement:
The filament spunbond needle-punched geofabric, with its reinforced fibers through needle-punching, effectively strengthens the soil, improving tensile strength and stability.
2, Prevention of Soil Erosion:
The geofabric covering helps slow down water flow, reducing soil erosion and preventing soil loss.
3, Filtration and Drainage:
Designed to allow water to pass through while blocking the passage of particles, the geofabric acts as a filter and facilitates drainage.
