Product Description

1.5mm/2mm/2.5mm/3mm Bituminous Hard HDPE Textured Composite Geomembrane in Heap Leach Pads/Waste Piles Sanitary Landfill Basal/Capping Liner

Composite geomembranes are engineered materials designed for superior impermeability, durability, and resistance to chemical and environmental degradation. They consist of a textured high-density polyethylene (HDPE) geomembrane bonded to a non-woven geotextile, combining the best properties of both materials. This composite structure enhances friction, puncture resistance, and stability, making it ideal for critical containment applications such as heap leach pads, waste piles, and sanitary landfill liners (both basal and capping layers).

HDPE Geomembrane is specially formulated. It is produced from high quality polyethylene, HDPE, together with pure polyethylene resin. This product contains many components. We can list these components as carbon black, antioxidant, anti-aging agent and UV resistance. Thus, HDPE geomembrane is produced by combining these components. We are the first among HDPE geomembrane manufacturers and we produce the best quality products for you.

Features & Benefits

1. Superior Impermeability & Leak Prevention

The HDPE core provides an exceptional hydraulic barrier, preventing the migration of liquids, leachates, and contaminants. The textured surface increases friction, reducing the risk of liner slippage in steep slopes.
 

2. Enhanced Durability & Puncture Resistance

The geotextile backing reinforces the geomembrane, improving resistance to punctures, tears, and stress cracks. This is crucial in applications with heavy waste loads, sharp aggregates, or dynamic settlement.
 

3. Chemical & UV Resistance

• HDPE is highly resistant to acids, alkalis, and industrial chemicals, making it ideal for heap leach pads (used in mining) where aggressive solutions like cyanide or sulfuric acid are present.

• UV-stabilized formulations ensure long-term performance in exposed applications such as landfill capping.
   

  4. Flexibility & Stress Crack Resistance

  Unlike rigid liners, textured HDPE geomembranes accommodate ground movement and subsidence without cracking, ensuring long-term containment effectiveness.

Application

 

1. Heap Leach Pads (Mining Industry)

In gold, copper, and uranium mining, heap leach pads use composite geomembranes to contain toxic leaching solutions (e.g., cyanide, sulfuric acid). The textured surface prevents liner slippage under ore piles, while the chemical-resistant HDPE ensures no leakage into the ground.

2. Waste Pile Liners

For industrial waste, coal ash, and hazardous material storage, these geomembranes provide a secure barrier against leachate seepage, protecting groundwater and soil from contamination.

3. Sanitary Landfill Liners (Basal & Capping Layers)

• Basal Liners: Prevent leachate from polluting subsurface soil and water.

• Capping Liners: Minimize rainwater infiltration, reduce gas emissions, and stabilize closed landfills.

4. Secondary Containment & Pond Liners

Used in wastewater treatment plants, oil & gas storage, and industrial lagoons, these geomembranes ensure zero leakage of pollutants.

FAQ

1. How long does an HDPE liner typically last?
An HDPE liner can last for up to 50 years or more, depending on the application and environmental factors.

2. What is the installation process for an HDPE liner?
The installation process for an HDPE liner typically involves excavating the area where the liner will be installed, laying down a layer of geotextile fabric, and then placing the HDPE liner on top. The edges of the liner are then anchored to prevent movement.
 

3. Can an HDPE liner be used for potable water storage?
While HDPE liners are commonly used for storing water, they are not typically used for potable (drinking) water storage. Specialized liners are required for potable water storage to ensure that the water remains safe to drink.

4. What is the cost of an HDPE liner?
The cost of an HDPE liner varies depending on its thickness, size, and other factors. However, HDPE liners are generally considered a cost-effective option compared to other types of liners.

5. What are the specifications for HDPE geomembrane used in gold mining heap leaching liner?
The specifications for HDPE geomembrane used in gold mining heap leaching liner vary depending on the specific application, but typically include thickness, permeability, and chemical resistance.
