Viuda de Sainz was established as a public limited company in 1984, as the natural continuation of a pre-existing family-owned business dating from the late 50s. Our activity started near Mount Arraiz, in Bilbao. Then, due to the need for more space, we moved to El Campillo industrial estate in Abanto-Zierbena (Bizkaia), where we now have our headquarters, with the main office, the machinery park and the technical services.
In recent years, we have carried out different construction projects such as: highways, roads, bridges, tunnels, viaducts, underground lines, environmental infrastructures, housing, industrial premises and works, together with sustained residential and industrial management and development.
