Engineering company

At Invall we have spent over 50 years confronting various engineering challenges for the public sector projects as well as the private sector. Our business focuses on managing projects related to land use, water engineering, renewable energy as well as the environment and telecommunications.

Throughout those years our technical team has specialized in different areas of activity, which has allowed us to be present in the entire value chain of the project: from feasibility studies, design projects, processing of licenses, management and supervision of works, project management and EPC (engineering, procurement construction).

In our quest for continuous improvement, we have a highly qualified team in constant training, which allows us to keep up to date for the new needs of the market as well as being at the cutting edge of the most demanding projects.

Also at Invall we have the recognition of international quality standards ISO 9001 and ISO 14001 Environment for all our activities.


Social Policy


In addition to our environmental commitment, we also want to generate a positive return to society, especially to the most disadvantaged ones. Therefore, we collaborate with various international NGOs like Oxfam, the Vicente Ferrer Foundation and Engineers without Borders.

We collaborate in an altruistic way with various international NGOs.    


Ethics Channel

At INVALL SA we believe in the importance of fostering a safe, ethical, equal, and trusting environment for all our employees, clients, and partners in general.

For this reason, we have implemented a robust Ethical Channel that allows anyone to report possible misconduct or ethical violations that they have detected in our organization. A channel where any possible non-compliance or irregularity can be reported to the organization, as described in Spanish Law 2/2023, of February 20th, regulating the protection of people who report regulatory and anti-corruption violations.


You can report through the Ethics Channel facts that you consider may constitute a breach of the legal regulations, the Code of Ethics, or any internal regulations in force, such as:

  • • Conduct related to fraud and corruption.
  • • Behaviors related to safety, health, and hygiene at work.
  • • Discrimination and harassment in the workplace.
  • • Conduct relating to information security, data protection and stock markets.
  • • Anti-competitive practices.
  • • Conduct contrary to human rights or damage to the environment.
  • • Other possible criminal or administrative violations.


Confidentiality: We understand that confidentiality is critical to encouraging people to report. We guarantee absolute confidentiality throughout the process and protect the identity of the reporting person to the extent permitted by law. It includes the possibility of making the alert anonymously.

Impartial Investigation Process: Once a complaint is filed, our team of experts will thoroughly investigate the matter objectively and diligently in accordance with internal regulations and applicable law. Throughout the entire process, the rights of those involved must be respected, in particular the presumption of innocence.

Protection against retaliation: We do not tolerate any form of retaliation against whistleblowers in good faith. We are committed to safeguarding the rights and integrity of those who dare to report any wrongdoing. We will take appropriate disciplinary action against any individual who retaliates against a whistleblower.

Diligence: The channel managers will diligently process the information that has been communicated to them. In any case, the necessary decision will be adopted within a maximum period of three months, except in cases of special complexity that require an extension of the period, in which case, it may be extended up to a maximum of another three additional months.

Resolution and Follow-up: After the investigation is concluded, we will take the necessary actions to address the problem identified and, where possible, take corrective action to prevent future violations. In addition, we are committed to keeping the whistleblower informed of the progress and resolution of their complaint whenever possible and permitted by law.
