A network of diverse professionals: COLLABORATIVE DIALOGUE

Civil engineers, along with agronomy, mechanics, electronics, chemistry and management experts from all over the world and with different cultures and working experiences come together as logical teams in order to transform an idea or a project into new successful products through the process of IDEA or Project management.
We would also like to note the constant investment in research and prestigious international collaborations. TENAX can therefore work alongside its partners in experimenting, developing and then producing highly innovative solutions.

TENAX has chosen over the past 50 years to give patent protection to its inventions; this decision represents TENAX’s continuous commitment to technological innovation and its devotion to research and to the consolidation and protection of its achievements. Over the years, TENAX has stamped its products with the its trademarks and has seen its reputation grow over time. Today these trademarks identify and distinguish the quality of the TENAX group products globally.

THE QUALITY: the LABORATORY and the TQM Total Quality Management:

The Laboratory

Modern testing instrumentation and the highly specialized personnel make up the TENAX Laboratory. The TENAX laboratory is capable of performing tests for measuring the mechanical, hydraulic and durability properties of plastic materials, in agreement with standard international methodologies. The TENAX Laboratory is constantly working in conjunction with Universities, research centres, and other specialized laboratories to consistently guarantee the highest levels of professionalism.

TQM Total Quality Management

The concept of quality is not an abstract or subjective concept, it is in fact based on the TOTAL QUALITY MANAGEMENT philosophy which identifies ascertainable and objective parameters of KEY PERFORMANCE INDICATORS that measure the quality of products or services produced by TENAX and allows the logical pursuit of continuous improvement. Here are some performance indicators used by PTEC in its projects and when performing technical support for facilities of the TENAX group as a whole:


The TENAX Quality Management System has been certified to be ISO 9001:2008 compliant by SGS Italy and by SGS UK, and this has been extended to the TENAX Tianjin China subsidiary.
The ISO 9001:2008 certification is based on procedures that aim for the continuous improvement of product and service quality assurance.
Each phase is monitored in all of its aspects: design, procurement, production and quality control on the finished product.

PRODUCT certifications
TENAX SPA has also obtained the EC seal for geosynthetic products under the Directive for construction products. The approval was issued by Kiwa MPA Bautest GmbH, German Notified Body with European recognition.

Other certifications
After rigorous examination, some TENAX geosynthetics have achieved important certifications from the highest international technical bodies for their use in structural works with a life-time of over one hundred years.
