An High Density Polyethylene geomembrane is a synthetic liner made from high-density polyethylene resin, designed to provide impermeable barriers for containment applications. With a density of 0.94 g/cm³ or higher, High Density Polyethylene geomembranes offer exceptional resistance to chemicals, UV radiation, and environmental stress cracking. They are widely used in industries such as waste management, mining, water management, and civil construction, ensuring environmental protection and operational efficiency.

1.2 Key Specifications of High Density Polyethylene Geomembrane

  • Thickness: Ranges from 0.2 mm to 3.0 mm (8 to 120 mils), with common options including 0.75 mm, 1.0 mm, 1.5 mm, and 2.0 mm.
  • Width: Standard rolls range from 4 to 10 meters (13 to 33 feet), customizable based on project needs.
  • Length: Rolls typically measure 50 to 100 meters (164 to 328 feet).
  • Tensile Strength: 15 to 35 MPa, ensuring durability under stress.
  • Colors: Black (with carbon black for UV resistance), white, or dual-colored (e.g., black/green) for aesthetic or functional purposes.
  • Surface Finish: Smooth or textured for enhanced friction on slopes.
  • Certifications: Meets GRI GM13 standards, ISO 9001, and OEKO-TEX for quality and safety.

High Density Polyethylene geomembranes are manufactured with 97.5% virgin polyethylene, 2.5% carbon black, and trace antioxidants and stabilizers, ensuring long-term performance (up to 50–70 years in optimal conditions).

2. Factors Influencing High Density Polyethylene Geomembrane Cost

The High Density Polyethylene geomembrane cost varies widely based on several factors. Understanding these can help you estimate budgets accurately and avoid unexpected expenses.

2.1 High Density Polyethylene Geomembrane Cost – Thickness

Thicker geomembranes cost more due to increased material usage and enhanced durability. For example:

  • 5 mm (20 mil): $0.50–$1.50 per square meter, suitable for lightweight applications like small ponds.
  • 0 mm (40 mil): $1.00–$2.50 per square meter, ideal for medium-sized reservoirs or fish ponds.
  • 0 mm (80 mil): $2.00–$4.50 per square meter, used in high-load applications like landfills.

Thicker liners (e.g., 2.0 mm) offer 30% greater puncture resistance than thinner options, justifying the higher cost for critical projects.

2.2 High Density Polyethylene Geomembrane Cost – Surface Type

  • Smooth High Density PolyethyleneGeomembranes: Cost $0.50–$4.00 per square meter, depending on thickness. These are standard for flat surfaces.
  • Textured High Density PolyethyleneGeomembranes: 10–20% more expensive ($0.60–$4.80 per square meter) due to enhanced friction for slopes (e.g., 3H:1V slopes).

Textured liners improve stability by 15% on sloped surfaces, reducing installation risks in projects like tailings dams.

2.3 High Density Polyethylene Geomembrane Cost – Raw Material Costs

High Density Polyethylene geomembrane prices are tied to polyethylene resin costs, which fluctuate based on crude oil prices and market dynamics.
