Our History is excavated underneath your feet

Our History

Exactly, since 1980. Then we began to work on the mining industry, both for underground and opencast mines, in the most important mines in Spain. After these beginnings, we gradually grew expanding our activities and specialties covering also the tunnels area. Until the last decade, when we started to participate in the most ambitious Civil Works and Rail Industry projects of the country. Thus, we have collaborated with such important clients as Renfe and Feve, and bring value to the development of major transport infrastructure such as the expansions of Metro de Madrid and Barcelona, the AVE –Spanish High Speed Trains- Madrid-Valladolid tunnels, or the underground burial of the Madrid M-30 High Road, among others.

Today, our services cover all types of claims that may arise in the mining or Public Works, such as the manufacturing of spare parts, repairing, technical support, maintenance and improvement of TBM, rolling stock, locomotives, etc.

In our customer base is not lacking any of the big national builders: FCC, DRAGADOS, Acciona, OHL, Ferrovial, Corsan Corviam, Sacyr, GEOCISA, Obras Subterráneas, VIAS y Construcciones, among others.
