As in the rest of civil works on bridges Composites ID work spans the materials cycle from research and development to the repair and reconstruction. Your goal is to get the highest performance materials with maximum benefit.

In the design and development issues concretes a characteristic of composites is that the concrete design of the traction performed. In 1998 he made ​​the first high-strength concrete and shrinkage compensated with additives such polycarboxylates in Morlans Viaduct in San Sebastián (fck> 50MPa) and vinyl based additives on the bridge of Spanish in Valladolid (fck> 60 MPa), in 2000, the Arc de los Tilos (fck> 80 MPa) up to now (fck> 150 MPa). The viaduct section Sagar in Eibar - Bergara (N) of the Basque Country highway design a quick-setting concrete and without retraction (fck> 35 MPa) to move quickly on issues centering on the building.

The topics mentioned repair and reconstruction repair girders heads in Hendaye (France - 2004) and some viaducts like the stretch Larreategui Eibar-Bergara (N) of the Basque motorway. In the last year has been dedicated Composites ID to obtain concretes with high ductility, compressive strength> 150 MPa and durability> 250 years.
