Worldwide recognition

More than 10,000 meters of pressure pipelines repaired with composite materials


Engineering and design with composite materials, effectively putting into practice the theoretical calculation hypotheses


Automated construction process, same mechanical properties at any point of the surface


Longevity in the useful life of the materials used, mitigating any future corrosion without maintenance.


Safe for workers and the environment in confined spaces, no risk of inhalation of vapors


Innovation, commitment

Our mission is to restore, replace or increase the structural integrity lost in the assets, providing the required mechanical properties at any point of the surface.

Pressure pipelines, infrastructures, equipment, tanks and reservoirs. We have consolidated a process of strategic change through technology transfer from the aeronautical sector to our sectors of activity.

We solve industrial deficiencies and incorporate new alternatives to traditional metallurgical solutions. We implement our solutions on-site, wherever our customers' needs are, keeping their equipment and facilities in operation with reliability, quality and safety.

JEC Innovation Awards

Grupo Navec's technology has been recognized by the most important organization for composite materials in the world as a technological innovation at the 'JEC Innovation Awards' in Paris, alongside renowned companies such as Airbus, Audi, BMW, Komatsu, Ford and Porsche, among others.

It consists of the in-situ construction of pipes and/or pressure vessels using carbon fiber, employing a methodology of high-strength epoxy resin infusion and homogeneous consolidation under vacuum pressure.

Its mission is to restore, replace or increase the structural integrity lost in infrastructures. Depending on the state of the base material, it can be considered as a lost mold, not contributing to the support of structural loads.


Long-term vision

In the commitment to a circular economy to conserve, maintain and extend the value of fluid distribution and storage networks and infrastructures, especially drinking water, Navec Group's technology has become, for years, a reality that demands a cultural and strategic change when rethinking the conservation of these facilities.

The homogeneous dosing of the constituent materials, effectively implementing the theoretical calculation hypotheses, the elimination of the human factor and the longevity of the composite materials, in terms of resistance to degradation and corrosion, ensure the reliability and homogeneity of the resulting assembly, and provide a long-term vision in the field of industrial, preventive and corrective maintenance.

The greatest advantage is found in buried systems where the logistical difficulties of access and auxiliary means can be an impediment due to the complexity of performance by traditional means, and in equipment with practically exhausted or discontinued useful life, without replacements.


What do we offer?

A safe, reliable and long-lasting alternative to traditional repair and maintenance methods, regulated by internationally recognized standards.


Study and design of customized solutions according to the needs of each client, with experience in more than 10,500 interventions in the last 10 years.


Specific calculations and intervention procedures according to ISO, ASME and AWWA standards, certified by an independent Authorized Control Body.


Testing and characterization of materials used, collaboration with universities, technology centers and external laboratories accredited by ENAC.


Turnkey projects with expertise and qualified personnel, certified inspectors and purchasing capacity of 45 M€ with more than 150 international suppliers.
