HDPE membrane, or HDPE geomembrane, is composed of high-density polyethylene material. It serves as a waterproof barrier, safeguarding structures from water and vapor, as well as protecting concrete against corrosive substances and ground salts. This versatile membrane is extensively utilized in geotechnical and environmental engineering projects, ensuring containment and shielding against contamination.

As the leading geosynthetics manufacturer and supplier, GEOSINCERE offers high quality HDPE membrane in custom thickness and size in bulk order at best factory price.

1. What is HDPE Membrane

HDPE membrane, also known as HDPE geomembrane, is a waterproof barrier material made from high-density polyethylene resin. Engineered with custom formulations, it possesses key properties such as strength, flexibility, and chemical resistance. Manufactured in long rolls, HDPE membranes are installed on-site as a barrier layer to contain liquids or prevent the migration of contamination.

One of the notable advantages of HDPE membrane is its exceptional resistance to environmental stress cracking, making it highly durable. It exhibits resistance to low temperatures, anti-aging properties, and corrosion resistance. With a wide operating temperature range of -60°C to +60°C and a service life of over 50 years, HDPE membrane is extensively used in various anti-seepage projects. These projects include domestic waste landfills, solid waste landfills, sewage treatment plants, artificial lakes, and tailings treatment facilities.

HDPE membranes create a continuous bond with poured concrete, remaining unaffected by ground settlement. This characteristic allows them to act as impermeable barriers, effectively preventing the passage of water, moisture, and gas. HDPE membranes also offer good puncture resistance during the placement of reinforcement bars, ensuring their integrity and performance. They are inert and highly resistant to chemicals, acids, bases, alkalis, and salts, providing excellent corrosion resistance in a wide range of environments.

3. What Is HDPE Membrane Used For?

3.1 Landscaping Application

HDPE water barrier can indeed be utilized as a root guard for trees, bamboo, and weeds, effectively preventing the spread of roots throughout the landscape. In such applications, customized HDPE membrane options are available, specifically designed for foundation waterproofing and root containment. The following are examples of the material dimensions and thicknesses commonly used in these cases:

3″ x 3″ Pieces: Available in 30 Mil, 40 Mil, 60 Mil, and 80 Mil thicknesses.

Rolls:

  • 10″ x 100′ Roll: 80 Mil Thickness
  • 18″ x 100′ Rolls: Available in 30 Mil, 40 Mil, 60 Mil, and 80 Mil thicknesses.
  • 24″ x 100′ Rolls: Available in 30 Mil, 40 Mil, 60 Mil, and 80 Mil thicknesses.
  • 30″ x 100′ Rolls: Available in 30 Mil, 40 Mil, 60 Mil, and 80 Mil thicknesses.
  • 36″ x 100′ Rolls: Available in 30 Mil, 40 Mil, 60 Mil, and 80 Mil thicknesses.
  • 48″ x 100′ Rolls: Available in 30 Mil, 40 Mil, 60 Mil, and 80 Mil thicknesses.
  • 48″ x 80′ Roll: 80 Mil Thickness
  • 60″ x 80′ Roll: 60 Mil Thickness

These dimensions and thicknesses provide a range of options to suit different project requirements and ensure effective root containment. The choice of size and thickness depends on factors such as the type of plant, the desired level of root restriction, and the specific landscape conditions.

By using HDPE membrane as a root guard, the spread of plant roots can be controlled, preventing potential damage to infrastructure, hardscapes, or adjacent planting areas. The impermeable nature of HDPE membrane effectively acts as a barrier, confining the roots and maintaining the desired landscape design and functionality.

3.2 Mining Application

 HDPE membrane plays a crucial role in ensuring environmental protection and regulatory compliance in mining operations by providing reliable containment solutions for various waste materials, process fluids, and water resources. Its impermeable properties, durability, and chemical resistance make it well-suited for the challenging conditions encountered in the mining industry.

3.2.1 Tailings Storage Facilities (TSF) Liners

HDPE membrane is used to line tailings storage facilities, which are used to store the waste materials generated from the mining process, known as tailings. The impermeable properties of HDPE membrane help to prevent the seepage of contaminants from the tailings into the surrounding soil and groundwater, minimizing environmental impact and protecting nearby ecosystems.

3.2.2 Heap Leach Pads

In heap leach mining operations, HDPE membrane is employed to line the leach pads where crushed ore is stacked and leaching solutions are applied to extract metals such as gold, copper, or uranium. The HDPE liner prevents the leachate solution from infiltrating into the underlying soil and groundwater, ensuring containment and environmental protection.

3.3 Evaporation Ponds

HDPE membrane is used to line evaporation ponds, which are used to store and evaporate water from mining operations, such as process water or wastewater. The impermeable barrier provided by the HDPE liner helps to minimize water loss through seepage and ensures proper containment of potentially contaminated water.

Water Storage and Treatment: HDPE membrane is utilized in water storage reservoirs, ponds, and treatment facilities associated with mining operations. The liner helps to prevent seepage and contamination of water sources, ensuring that water used for mining processes or discharged from operations meets environmental regulations and quality standards.
