Industry Comparison

Application Scenarios

HDPE Geomembrane for Industrial is specified by distributors and EPC contractors in:

• Mining leach pads and tailings storage facilities

• Chemical plant secondary containment ponds

• Industrial wastewater treatment lagoons

• Hazardous waste landfill liners

• Power plant ash ponds and slurry containment areas

Key Pain Points and Solutions

• Chemical leakage risk: High-density polymer matrix provides excellent chemical barrier.

• Stress cracking failures: Optimized resin and OIT values improve long-term resistance.

• Installation damage: High puncture resistance reduces handling and placement risks.

• UV degradation: Carbon black stabilized formulation ensures outdoor durability.

Risk Warnings and Mitigation Recommendations

• Avoid installation on sharp subgrade; use protective geotextile underlayment.

• Control welding temperature and pressure to prevent weak seams.

• Limit prolonged exposure before cover placement in extreme climates.

• Verify chemical compatibility with stored media prior to final material selection.

Procurement and Selection Guide

1. Define containment type and expected chemical exposure profile.

2. Confirm required geomembrane thickness based on hydraulic head and loading.

3. Specify smooth or textured surface based on slope stability calculations.

4. Request certified laboratory test reports for each production batch.

5. Evaluate seam strength requirements and field welding procedures.

6. Audit manufacturer production capacity and quality management systems.

7. Plan logistics for roll size, site storage and handling equipment.

Engineering Case Example

In an industrial wastewater treatment project, a 2.0 mm thick HDPE Geomembrane for Industrial was installed over a compacted clay subgrade with nonwoven geotextile protection. Factory prefabricated panels were field welded using hot wedge welding. Post-installation vacuum box testing confirmed seam integrity, and leak detection surveys recorded zero defects.
