What standards can your geomembranes be manufactured to?

Our geomembranes can be manufactured according to applicable project specifications and recognized standards, including GRI specifications and relevant Chinese standards such as GB/T 17643 and CJ/T 234. ASTM methods are used for relevant physical and mechanical testing. The applicable standard should be confirmed before production so that the product specification and test requirements are aligned with your project.

How do you control product quality and batch consistency?

We control quality from raw-material inspection through production and finished-product testing. Production parameters and product dimensions are monitored during manufacturing, while finished products are tested according to the applicable specification. Production records and test reports are maintained for traceability. We can provide factory test documentation and supporting quality records according to the project requirements.

Can you provide test reports, certificates and third-party inspection?

Yes. We can provide factory test reports and relevant product documentation. Third-party inspection or laboratory testing can also be arranged when required by the customer or project specification. The testing scope, laboratory and associated cost are confirmed according to the required standards and inspection requirements.

What warranty do you provide?

We provide product warranties covering applicable manufacturing and material defects, subject to the product type, agreed specification, installation requirements and conditions of use. The applicable warranty period and terms are confirmed in the quotation or sales contract. Warranty coverage does not replace the need for proper product selection, installation and project-specific quality control.
