hdpe geomembrane price per sqm

HDPE geomembrane is a high-density polyethylene impermeable liner used for fluid containment and environmental protection. When evaluating HDPE geomembrane price per sqm, buyers must consider material grade, thickness, standards compliance, and long-term performance rather than unit cost alone.

Technical Parameters and Specifications

Standard HDPE Geomembrane Specifications

• Raw material: Virgin HDPE resin

• Density: ≥0.94 g/cm³

• Thickness range: 0.75 mm – 3.0 mm

• Tensile strength: ≥15 MPa (ASTM D6693)

• Elongation at break: ≥700%

• Carbon black content: 2.0–3.0%

• Oxidative induction time: ≥100 min (Std OIT)

• Hydraulic conductivity: ≤1×10⁻¹³ m/s

Structure and Material Composition

HDPE Geomembrane Sheet Composition

• Primary polymer matrix: High-density polyethylene resin

• Carbon black dispersion: UV protection and durability

• Antioxidant package: Thermal and oxidative resistance

• Optional surface texture: Smooth or textured (single/double side)

Manufacturing Process

1. Resin Selection and Blending

Certified HDPE resin is blended with carbon black masterbatch and antioxidants. Resin quality directly influences mechanical performance and affects final HDPE geomembrane price per sqm.

2. Extrusion Process

Flat-die or blown-film extrusion equipment produces continuous geomembrane sheets. Thickness control systems ensure uniformity, which is critical for meeting ASTM and ISO requirements.

3. Cooling and Surface Treatment

Sheets are cooled, trimmed, and optionally textured to improve interface friction in slope applications.

4. Quality Inspection

Each production batch undergoes tensile, thickness, density, and OIT testing. Compliance testing adds cost but reduces long-term project risk.

Industry Comparison

Application Scenarios

• Distributors: Bulk purchasing based on thickness and roll size

• EPC Contractors: Cost optimization for large-scale lining projects

• Engineering Consultants: Budget estimation and material specification

• Importers / Wholesalers: Price benchmarking across suppliers

Core Pain Points and Solutions

• Unclear price differences: Compare HDPE geomembrane price per sqm by thickness and resin grade

• Hidden quality reductions: Verify density, OIT, and carbon black content

• Over-specification: Match liner thickness to actual engineering loads

• Logistics cost impact: Optimize roll dimensions and container loading

Risk Warnings and Avoidance Recommendations

Low HDPE geomembrane price per sqm may indicate recycled resin use, insufficient antioxidants, or non-compliance with standards. Risk mitigation includes third-party testing, factory audits, and detailed technical submittal review.

Procurement and Selection Guide

1. Define application and regulatory requirements

2. Select required geomembrane thickness

3. Confirm applicable ASTM or ISO standards

4. Request technical datasheets and test reports

5. Compare HDPE geomembrane price per sqm on identical specifications

6. Evaluate supplier production capacity and quality control

7. Assess logistics, packaging, and delivery terms

Engineering Case Example

A 120,000 m² industrial wastewater project evaluated multiple suppliers based on HDPE geomembrane price per sqm for 1.5 mm thickness. By selecting ASTM-compliant material with optimized roll sizes, the EPC contractor reduced total installed cost while maintaining long-term liner performance.

Frequently Asked Questions (FAQ)

• What affects HDPE geomembrane price per sqm most? Thickness and resin quality.

• Is thicker always better? No, thickness should match engineering design.

• Does texture increase price? Yes, due to additional processing.

• Are recycled materials cheaper? Yes, but performance is reduced.

• Do standards affect price? Certified products cost more but reduce risk.

• Is installation included? Usually not; material price only.

• Typical roll width? 5–8 meters depending on manufacturer.

• How to compare suppliers? Use identical specs and test criteria.

• Does UV resistance affect cost? Yes, through additives.

• Can pricing vary by order volume? Yes, bulk orders reduce unit cost.
