Founded in the 1920's by an engineer, Sante Astaldi, the company has been successfully run by his nephews Mario and Gianfranco, who are being  followed by a third generation of the Astaldi family.
Up to the second world war, the Astaldi company was primarily involved in major civil works projects in Italy and abroad, including railroads, aqueducts, ports and public buildings. The Rome-Naples railroad, the Favara aqueduct in Sicily, the piers in the port of Gaeta, and the Addis Abeba-Great Lakes road are all projects from this period.

After the war, in addition to a major presence in Italy, Astaldi extended its activity to Africa, initially in Kenya and Uganda in joint venture with an English businessman, John Stirling, and later (1950’s) on its own in Zaire, Ghana, Sierra Leone, Nigeria, Burundi, Rwanda and  Mozambique. Its activity in Africa primarily involved road construction. In Italy, Astaldi focused on post-war reconstruction particularly hydraulic plants and railroads projects such as the Sarca power plant in Molveno and the Milan-Venice railroad line.

In 1950, following the opening of foreign markets Impresa Astaldi Estero S.p.A. was established, while Impresa Astaldi Costruzioni e Lavori Pubblici S.p.A. continued to operate in Italy.

Between the 1950's and 1970's, the Group expanded its presence in Africa (Somalia, Zambia, Guinea, Ivory Coast, Libya, Gabon, Angola), in the Middle East (Lebanon and Saudi Arabia), in Central and South America (Venezuela and Honduras) and in the Far East (Pakistan and Thailand). The Group's foreign activity in this thirty year period covered a wide range of projects (roads, airports, hydroelectric and industrial plants) with a major increase in size and operational complexity.

During the same period, the Astaldi Group managed important civil engineering jobs in the italian market including railroads, roads, motorways, hydraulic power plants, dams, aqueducts and sewage systems, such as the Cimego power station, the Trento-Malè railroad line, the Autostrada del Sole motorway, and the Osento dam.

During the 1980's the two companies, Impresa Astaldi Estero SpA and Impresa Astaldi Costruzioni e Lavori Pubblici SpA merged due to operating needs and they became the present Astaldi SpA, with headquarters in Rome. In addition to the "traditional" civil works during this period the Group built the PEC nuclear power plant in Italy and the plant for metalworking in Taranto.

Late in the 1980's and from the 1990's Astaldi, entered new markets in the Far East (Indonesia), in Europe (Romania and Denmark), in the United States and Turkey. Orders during this period included complex jobs such as subways and hydroelectric power plants, both in Italy and abroad.

A fundamental step in the industrial development of the Group, presently engaged in several important works all over the world, was the acquisition of two important national construction companies, Italstrade and Dipenta.

Following these acquisitions, the Group ranked second in the segment of general contractors in Italy.  From 1988 the annual revenue, including Italstrade and Dipenta, exceeds 1,500 billion lire with an extremely diversified geographical location enabling the Group to lay down the basis for further expansion.
