| Density | ≥ 0.940 g/cm³ | ASTM D1505 |
| Tensile Strength (Yield) | ≥ 22 kN/m | ASTM D6693 |
| Elongation at Break | ≥ 700% | ASTM D6693 |
| Puncture Resistance | ≥ 480 N | ASTM D4833 |

| Oxidative Induction Time (OIT) | ≥ 100 min | ASTM D3895 |
HDPE geomembrane price per square meter 1.5mm varies depending on raw material grade, UV resistance package, and roll width (typically 5–8 meters).
Structure and Material Composition
1.5mm HDPE geomembrane is typically manufactured as a homogeneous sheet but contains engineered components:
High-Density Polyethylene Resin – Virgin PE100 or equivalent grade.
Carbon Black (2–3%) – UV stabilization.
Antioxidant Package – Thermal aging resistance.
Optional Surface Texture – Improved friction for slopes.
Understanding composition helps interpret HDPE geomembrane price per square meter 1.5mm in relation to durability and design life (20–50 years depending on exposure).
Manufacturing Process
1. Raw Material Preparation
Virgin resin blending with carbon black masterbatch using gravimetric dosing systems.
2. Extrusion
Flat die or blown film extrusion lines. Temperature control 200–240°C. Automatic thickness monitoring ensures 1.5 mm uniformity.
3. Calendering & Surface Texturing
Optional embossing rollers for textured geomembranes used in landfills and mining.
4. Cooling & Winding
Water-cooled rollers, edge trimming, spark testing, and automated winding into rolls (50–200 m length).
5. Quality Control
On-line thickness scanning, tensile sampling, and carbon black dispersion testing.
Production efficiency, automation level, and QC rigor directly influence HDPE geomembrane price per square meter 1.5mm.
Industry Comparison
| Material | Thickness | Durability | Relative Cost | Typical Use |
|---|---|---|---|---|
| HDPE 1.5mm | 1.5 mm | High | Medium | Landfill base, ponds |
| HDPE 2.0mm | 2.0 mm | Very High | Higher | Hazardous waste |
| LLDPE 1.5mm | 1.5 mm | Flexible | Similar | Irregular subgrades |
| PVC Liner | 1.5 mm | Moderate | Lower | Temporary containment |
In cost-performance balance, HDPE geomembrane price per square meter 1.5mm is widely considered optimal for municipal solid waste landfills and large reservoirs.
Application Scenarios
EPC Contractors: Landfill base liners and capping systems.
Mining Operators: Heap leach pads and tailings ponds.
Water Infrastructure Developers: Irrigation canals and reservoirs.
Industrial Parks: Wastewater lagoons.
Importers/Distributors: Bulk roll supply for regional projects.
HDPE geomembrane price per square meter 1.5mm becomes critical in projects exceeding 50,000 m² due to scale impact.
Core Pain Points and Solutions
1. Budget Uncertainty
Solution: Lock raw material index-based contracts.
2. Installation Damage Risk
Solution: Use protective geotextile cushion layers.
3. Weld Seam Failure
Solution: Dual-track wedge welding with air channel testing.
4. UV Degradation in Exposed Areas
Solution: Specify adequate carbon black and antioxidant package.
Risk Warnings and Avoidance
Avoid recycled-content liners for critical containment.
Verify OIT results for long-term oxidation resistance.
Ensure subgrade compaction and debris removal.
Conduct destructive seam peel and shear tests per ASTM D6392.
Lowest HDPE geomembrane price per square meter 1.5mm may indicate compromised resin quality.
Procurement and Selection Guide
Define containment category (municipal, industrial, hazardous).
Confirm regulatory compliance (local environmental code).
Specify mechanical properties (puncture, tensile).
Compare supplier QC reports and third-party lab results.
Calculate total installed cost (material + welding + testing).
Request trial roll sample and inspection before bulk order.
Review logistics plan (roll weight 800–1600 kg typical).
Comprehensive evaluation ensures correct interpretation of HDPE geomembrane price per square meter 1.5mm beyond material-only quotation.
Engineering Case Study
