Control the quality of raw materials, components, production processes and finished products.


All raw materials, fibers or components required for the production of our geosynthetics undergo strict quality control at every stage. Raw materials must be provided by suppliers that meet international standards.


In the production process of all geosynthetics, strict quality assurance measures have been implemented. In order to ensure quality, an independent quality inspection department has been established and a first-class quality inspection laboratory has been established.


The entire company is produced and managed in accordance with the ISO international quality certification system. MTTVS® products successfully passed the EU CE certification.


MTTVS® geosynthetics undergoes quality inspection by a third party twice a year. Independent experts randomly select test samples from semi-finished products and various stock products in MTVS® production. All products can meet the specified quality standards.
