We have vast experience in the development of mining projects of different sizes. We build tunnels, caverns, shafts, chimneys, industrial plants, industrial assemblies, mining developments and we carry out mineral extraction work.
Thanks to our long history in underground handling, drilling, blasting and transportation of minerals, we are qualified to participate in underground mining contracts, where we use methods such as "Cut and Fill" and "Sublevel Stopping".

In its construction, applied technology and advice from globally recognized companies play a relevant role. This type of works are executed in a circular or rectangular shape, with Concrete or Shotcrete coating, at depths that vary between 20 and 1.000 meters. In addition, we have all the equipment to develop downward climbs, using the Alimak Climbing Cage for ascending work. We add to this experience the development of works under the Raise-Borer and Boxhole methodology.

We build tunnels and vaults excavated in different types of rocks, with the use of shotcrete as a fortification element. Applying the NATM methodology allows us to reduce times with the help of a primary Shotcrete coating and topographic monitoring of deformations.
