Quality and Certifications

A NETWORK OF PROFESSIONAL DISCIPLINES FOR INNOVATIVE APPLICATIONS

Another aspect that makes the TENAX Group unique is the collaborative dialogue that takes place between professional people from different disciplines.
Civil engineers, along with agronomy, mechanics, electronics, chemistry and management experts from all over the world and with different cultures and working experiences work together on projects sharing their particular knowledge in team based work programmes. This results in a wide input of ideas and expertise into the design of new products.

CONTINUOUS CO-OPERATION WITH COMPANIES TO CREATE NEW DEVELOPMENTS

Investment in research and in prestigious international collaborations has lead TENAX to build up and create a broad and diversified fund of knowledge. Working in close contact with its partners and clients, TENAX experiments, develops and the promotes highly innovative solutions

TENAX RESEARCH PUSHES TO ITS FURTHEST LIMITS

Discovering new fields for experimentation is a TENAX mission. TENAX’s research on new applications of geogrids and geocomposites is developed to the highest technical levels so that TENAX occupies a pre-eminent position. This research covers a number of scientific and technical fields.

Environmental compatibility has more recently been seriously considered: TENAX has designed sophisticated environmental engineering systems for erosion control and for the creation of grassed or planted retaining structures.

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 identified its products with its trademarks and has seen its reputation grow over time.
Today these trademarks 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.

 

LABORATORY TESTS:

  • Wide width and single rib tensile test
  • Peel and shear tensile junction strength
  • Tensile creep and tensile junction test
  • Puncture resistance (CBR) test
  • Hardness and density test
  • Long and short term hydraulic transmissivity tests
  • Soil/geosynthetic direct shear test
  • Pull-out test
  • Large scale yield
  • Laboratory testing on Geosynthetic damage
  • Melt Flow Index
  • Oven ageing test (thermo-oxidation)
  • U.V. exposure
  • Carbon Black test

All laboratory test results are stored in a computerised data bank which makes them constantly available online for the necessary quality assurance as well as for the development of new products and innovative solutions. Thus, these knowledge resources constitute a valuable source of information and data for the Group, and also a very useful tool for the universities for which TENAX is an important reference for the study of materials and their application.

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:

KPI PRODUCT

  • Mechanical Properties and Parameters Machine Direction
  • Mechanical Properties and Parameters Transversal Direction
  • Visual Quality Inspection
  • Dimensional and Physical parameters
  • Product Delta Cost within Simulation and Validation Testing of a pilot device or system

KPI SERVICE

  • Innovation Technology Degree
  • Product Innovation Degree
  • Technical Services Lead Time
  • Technical Service Quality
  • Project Efficiency (Time, Cost, Risk Management)

THE CERTIFICATIONS

SYSTEM CERTIFICATIONS

Quality has always been a strategic objective for TENAX in order to ensure maximum customer satisfaction.
The TENAX Quality Management System has been certified to be ISO 9001:2015 compliant by SGS Italy and by SGS UK.
The ISO 9001:2015 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.
