Emcor was set up in 1978 at Oviedo in northern Spain to supply equipment and material for underground coal mining. The company introduced innovative systems that helped to improve productivity, both in the local Asturias mines and in the rest of Spain, and also supplied equipment to South American mines.
The professional team that grew out of this work has allowed Emcor to expand, and it now has four well-defined business units serving the mining, tunnelling and civil engineering, railway, and environmental sectors.

A variety of TH steel arches and profiles are available to norm DIN 21544, together with welded joint plates, clamps and bolts. Metal supports in I and U, profiles HEB, IPN and UPN are also supplied. Bernold plate is delivered flat, or rolled to customer’s requirements.
Shotcrete fibre to improve the mechanical properties of concrete is supplied as glued or loose type in biodegradable bags of 20 kg or large bags of 1,000 kg. The addition of steel fibre to shotcrete helps control cracking, resists shrinkage stresses, and increases durability. Emcor fibres have a tensile strength from 900-1,400 N/mm2 and diameters from 0.55 mm to 1 mm. Dosing machines with automatic weighing system are available for sale or rent.
Emcor supplies a full range of environmental equipment for tunnelling, including ventilation pipes and fans, air quality instruments, and self-rescuers.
Hydraulic drill rigs, drill steel and bits, and roadheaders are also supplied, together with belt conveyors, monorails, rolling stock and locomotives.
Emcor supplies dust control systems, filters and cyclones, smoke filters, wheel-wash systems and mobile crushers and screens to markets in Spain, the European Union and the Americas. Products are approved
officially and certified according to European Union norms, and have ISO 9001:2000 quality certification.
Emcor continues to adapt to customer’s requirements, applying thirty years of underground mining experience to the tunnelling industry with great success. Amongst recent references are major construction companies such as Bouygues Construction, Spie Batignolles,
Semaica, ACS, Acciona, Ferrovial, Dragados and FCC.
