Frequently Asked Questions

What thickness HDPE liner is recommended for hydraulic engineering?

For most hydraulic applications, we recommend 1.5mm (60 mil) as a standard specification. For high-stress applications or rocky subgrade conditions, 2.0mm (80 mil) provides additional puncture resistance. Our team can provide specific recommendations based on your project conditions.

Standard: 1.5mm Heavy Duty: 2.0mm

What is the expected lifespan of HDPE geomembrane in water applications?

Under normal operating conditions, HDPE geomembrane liners have an expected lifespan of 50+ years in exposed conditions. With proper installation and protective measures, this can extend to 70-50+ years. The material's resistance to UV, chemicals, and environmental stress cracking ensures long-term performance.

50+ years exposed 70-50+ years covered

Can HDPE liner be used for potable water storage?

Yes, NSF 61 certified HDPE geomembrane is available for potable water applications. This certification ensures the material does not impart any taste, odor, or toxicity to the stored water. Please specify NSF 61 requirement when requesting a quote.

NSF 61 Available Food-Grade Material

What is the temperature operating range?

HDPE geomembrane maintains its properties in temperatures from -60°C to 60°C (-76°F to 140°F). This makes it suitable for use in all climate zones, from arctic regions to tropical environments.

-60°C to 60°C All Climates

How are seams between panels welded?

Field seams are typically made using dual-track hot wedge welding for main seams, which creates a weld with strength exceeding 95% of the parent material. Extrusion welding is used for detail work, repairs, and connections to structures. All welding is performed by certified technicians and tested non-destructively.

Dual-Track Hot Wedge Extrusion Welding

What subgrade preparation is required?

The subgrade must be smooth, compacted, and free of sharp objects, stones larger than 12mm, and organic material. A protective geotextile underlayer is recommended for rocky or abrasive subgrade conditions. We provide detailed installation specifications for each project.

Compacted Surface No Sharp Objects

What testing and certification is provided?

Every roll comes with batch test reports including thickness, density, tensile strength, elongation, ESCR, and HPOIT values. Third-party SGS or similar testing is available upon request. We provide certificate of conformance with each shipment.

Batch Test Reports SGS Testing Available

What is the lead time for orders?

Standard roll inventory is typically available for shipment within 5-7 working days. Custom specifications or large orders may require 2-4 weeks for production. Factory panel fabrication adds approximately 5-10 working days to the lead time.

5-7 days standard Custom: 2-4 weeks

What warranty is provided?
