HDPE Geomembrane

Zhonglongʼs HDPE Geomembrane For Sale

The HDPE geomembrane is a high-performance geosynthetic impermeable material, widely used for environmental containment and waterproofing projects. It is manufactured from high-density polyethylene (HDPE) resin through advanced extrusion and co-extrusion processes.

The geomembrane is formulated with anti-UV, anti-oxidation, and anti-aging additives, giving it exceptional durability and chemical resistance under long-term exposure to sunlight and harsh environmental conditions.

Its molecular structure provides excellent tensile strength, puncture resistance, and low permeability. The smooth surface version ensures superior seepage control and easy installation, while the textured surface enhances frictional performance on steep slopes.

When used in landfill liners, mining ponds, reservoirs, and wastewater treatment systems, the HDPE geomembrane acts as an effective barrier to liquids and gases, ensuring reliable environmental protection and long-term performance. It is recognized as one of the most advanced and durable impermeable geosynthetic materials available today.

Product Category of HDPE Geomembrane

Our company's HDPE Geomembrane are mainly classified two types based on their processes and application scenarios：

HDPE Geomembrane (Smooth Type)

It is an impermeable geosynthetic liner made from high-density polyethylene resin through extrusion and calendaring processes. Featuring a smooth surface on both sides, it provides excellent chemical resistance, UV stability, and low permeability, making it ideal for applications such as landfill liners, wastewater ponds and liquid containment systems.

HDPE Geomembrane (Textured Type)

It is a geomembrane liner with one or both sides textured to enhance friction and interface stability. Manufactured from high-quality HDPE resin, it offers superior shear strength and slope stability while maintaining outstanding impermeability. Compared with the smooth, it is commonly used in steep slopes, mining tailings ponds and other areas requiring high friction performance.

HDPE Geomembrane Core Features

1. High-quality raw materials

HDPE geomembranes consists of 97.5% high-density polyethylene and about 2.5% carbon black, anti-aging agent, antioxidant and UV absorber and other auxiliary materials to ensure superior product performance.

2. Excellent performance

HDPE geomembrane has strong anti-seepage and isolation capabilities and is suitable for a variety of environments.

3. Advanced technology

HDPE geomembrane adopts the leading four-layer co-extrusion process to ensure product quality and stability.
