Each roll of Atarfil geomembrane has its own identification number. The individual control sheet, or roll certificate, contains details of the results of the tests carried out on the geomembrane in line with the frequency set in the quality control plan. These roll certificates are dispatched to the customer with each delivery and can also be downloaded from our website.

Naturally, roll certificates confirm the statistical cloud that reflects the product specification sheet. Atarfil can add the necessary documentation or modify the packaging for countries and territories with special product certification requirements. The standard product guarantee is 10 years.

The guarantee is issued in the customer’s name or, upon request, in the name of the installation’s end user. It is linked to the delivery note number and invoice, which are issued at the point of supply, together with the rest of the documentation.

The guarantee is also backed by a civil liability insurance policy issued by a major international insurance company.

Under special circumstances, Atarfil may consider additional guarantee conditions and include any other documentation required by the customer. Please note that legal limitations mean that under no circumstances can civil liability insurance coverage exceed 10 years.
