Civil works

We have recognized prestige in delivering solutions for the construction sector in the mining area. We are supported by our experience in excavations and massive filling, foundations, walls, slabs, concrete, reinforcement, forms, railway lines and mailboxes.

Assemblies

We are experts in the development and execution of assembly projects for heavy equipment, structures, tanks and boilers, as well as transformers, substations, pumps, electrical rooms, instrumentation, mills, belts, crushers and piping, among others.

We implement electrical assembly, wiring, connection and commissioning of power and control of equipment and instruments. We develop underground electromechanical assemblies (from the electromechanical assembly of mineral transfer mailboxes to the installation of electrical and communication lines in tunnels).

Always attentive to the needs of our clients, we are highly trained to implement these EPC (Engineering, Procurement and Construction) projects, with the aim of seeking technically viable solutions that facilitate the start-up of the project with savings in time and costs.

Caverns / Tunnels / Raises

The construction of water conduction tunnels for hydroelectric plants and caverns of various lengths and sections are samples of the experience that Mas Errázuriz has in this field.

We incorporate a wide range of low-profile equipment with the highest technology to undertake the work with the precision and promptness required in drilling, blasting, loading, transportation, excavation, concrete spraying and reinforcement.

Infrastructure

In line with diversification, we develop public infrastructure projects of various complexities. This ranges from road tunnels, rainwater collectors, excavated underground, to other large-scale works such as Line 4 of the Santiago Metro. Chile.
