We implement a quality assurance system to the manufacture and installation of our geomembranes, guaranteeing maximal quality. Welds can be inspected by various methods, including ultrasound.

These waterproofing systems are implemented in compliance with local regulations and reference systems. For example: CETU technical approval and ASQUAL certification in France. Additional internal specifications can also be implemented. Please contact your local representative for more details.
