SEIS´s plants are prepared to build different types of precast concrete elements.  

They have a combined surface area of 100 Ha. and are equipped with powerful, modern means of production, manipulation and transport with automatic machinery and equipment to mechanize the work processes.  The employees are well experienced and have the know-how necessary to successfully develop and carry out any prefabrication proposal.

Ambitious R+D+i programs have placed SEIS's plants at the head of the field with innovative precast elements such as beams with great spans built of high strength concrete, noise barriers for highways and railroads, segments to line tunnels, etc.
