PRODUCT DETAILS
1. High Density Polyethylene (HDPE) Geomembrane Liner
Our HDPE Geomembrane Liner is the most widely used geosynthetic product in the world for containment applications. Manufactured from premium virgin polyethylene resins, this impermeable sheet provides a robust and reliable barrier against seepage and environmental contamination. Known for its exceptional durability, chemical inertness, and long service life, HDPE Geomembrane is the foundational element for critical infrastructure, environmental protection, and valuable resource containment. We produce liners ranging from 0.3mm to 3.0mm to meet stringent global standards, including ASTM GRI-GM13.
2. Core Advantages of HDPE Geomembrane
-
Unrivaled Chemical Resistance: HDPE is inherently inert, making it highly resistant to a vast range of chemicals, acids, alcohols, and waste leachate found in industrial and municipal environments.
-
Superior Anti-Seepage: The low permeability coefficient of HDPE creates a near-perfect watertight barrier, crucial for preserving water resources and protecting groundwater.
-
Excellent UV Stability: Formulated with 2.0% to 3.0% Carbon Black, our liners offer outstanding resistance to UV degradation, making them suitable for prolonged exposed applications.
-
High Durability & Longevity: Offers exceptional tensile strength, tear resistance, and puncture resistance, ensuring a design life that can exceed 50 years when buried.
-
Cost-Effective Solution: HDPE is the most economical geomembrane material per square meter for large-scale engineering projects.
3. Surface Options and Specifications
To accommodate diverse engineering requirements, our HDPE Geomembranes are available in three primary surface finishes, each serving a specific structural purpose:
3.1 Smooth HDPE Geomembrane
-
Application: Ideal for flat basal areas, bottom liners, and low-friction applications where maximum intimate contact and high liquid flow rates are required.
-
Key Feature: Easier to clean and suitable for pre-fabrication welding.
3.2 Textured HDPE Geomembrane
-
Application: Essential for steep slopes in landfills, reservoirs, and mining heap leach pads.
-
Key Feature: The rough surface dramatically increases the interface friction angle, preventing slippage of overlying soil, protective layers, or waste mass. Available in single-sided and double-sided textures.

Geomembrane FAQs
1.What is a geomembrane used for?
Geomembranes primarily serve as low-permeability barriers and are widely utilized in the base lining and capping of landfills, tailings dam containment, and the construction of landscape ponds and water reservoirs. In municipal and transportation engineering, they are frequently employed for tunnel waterproofing, basement damp-proofing, and roadbed reinforcement to prevent the seepage of liquids and hazardous substances, thereby safeguarding the safety of groundwater environments.
2. HDPE vs LLDPE vs PVC geomembrane: which should I choose?
Thanks to its exceptional chemical stability and UV resistance, HDPE is the preferred choice for long-term projects such as landfills. LLDPE offers superior flexibility and elongation properties, making it suitable for complex terrains and irregularly shaped containment applications. PVC, known for its excellent conformability, is frequently used in non-exposed applications—such as tunnels or underground structures—for leak repair and sealing purposes.
3. What thickness of geomembrane do I need for a pond or landfill liner?
The selection of thickness must be based on pressure testing results and specific geological conditions. Typically, a minimum thickness of 0.75 mm (30 mil) is recommended for landscape ponds. For high-risk projects such as landfills, the GRI-GM13 standard recommends a base liner thickness of no less than 1.5 mm (60 mil). If the site involves sharp rock fragments or is subject to extremely high hydrostatic pressure, the thickness should be increased to 2.0 mm, accompanied by the use of a protective geotextile layer.
4. What QA/QC documents should a geomembrane manufacturer provide?
Manufacturers are required to provide a Material Test Report (MTR) that includes batch tracking records and covers key performance indicators such as tensile properties, tear strength, carbon black content, and OIT (Oxidative Induction Time). Additionally, the documentation must include a Certificate of Conformity (COC) adhering to ISO/ASTM standards, reports on the raw resin materials used, and records of in-process monitoring data collected during manufacturing.
5. How are geomembrane seams welded and tested?
Dual-track thermal fusion welding is the industry-standard method; this process utilizes extrusion or a hot wedge to create a pair of parallel weld seams, leaving an air channel between them. Testing is categorized into non-destructive methods (such as vacuum box testing or air pressure testing, which ensure stable pressure within the air channel) and destructive methods (such as peel and shear tests), ensuring that the weld strength meets or exceeds 90% of the base material's standard value.
6. What is the service life of an HDPE geomembrane liner?
In a buried environment, a compliant HDPE geomembrane has a theoretical service life exceeding 100 years at a constant temperature of 20°C. When used in exposed applications, the service life is influenced by ultraviolet radiation and typically ranges between 20 and 30 years. Its durability depends primarily on the antioxidant content within its formulation and the rate at which these antioxidants are depleted under environmental stress.
