Our history

HEYMO’s innovative project was born in 1964, in full industrial development in Spain, thanks to the vision and enthusiasm of two great engineers: Rafael Heredia and Anselmo Moreno

Initially, the activity focused on the execution of construction projects and singular buildings, gradually extending to projects related to industrial and chemical processing plants, wastewater treatment, transportation facilities, gas and pulp and paper distribution.

In a few years, HEYMO extends its activity to foreign markets, signing, among others, turnkey contracts for a fertilizer plant in Venezuela, the Durán-Quito pipeline (Ecuador), or a Meliá Hotel in Bagdad (Iraq).

This year the name of the company was changed to “HEYMO INGENIERÍA, S.A.” and the entry into the capital of Finnish engineering Pöyry (60%) and Técnicas Reunidas (40%).

During the 1990s, significant international activity was achieved in industrial plants, pipeline transportation, cogeneration plants, infrastructure and the telecommunications market.

The considerable increase in business in the power generation sector prompted the creation of a specific business area. Combined cycle, cogeneration, biomass or thermosolar plant projects are carried out, while project development continues in traditional areas such as hydrogen plants, paper mills, unique buildings or fuel transportation pipelines.

As of 2015, HEYMO will be 100% owned by Técnicas Reunidas, reinforcing itself with the absorption of the Water Engineering and Infrastructures teams that previously formed part of TRIMA (Técnicas Reunidas Infrastracture and Environment).
