Construction engineers André Garczynski and Gaston Traploir met in the trenches of World War I. After the war, they created a company in Le Mans to build electrical networks. The company soon became a leader in western France. In the 1930s, it added water services to its business portfolio.
After world War II, Garczynski Traploir became a subsidiary of Compagnie Générale des Eaux. The company recorded spectacular industrial growth, driven by demand for high-voltage power lines, water towers and power plants.
In 1970, Garczynski Traploir's activities were combined with those of Mors Jean Bouchon and Fournié-Grospaud within a holding company called UEER, which later became GTIE. Garczynski Traploir is specialised in electrical power, information and communication technologies and has continued to develop within GTIE, VINCI's Energy and Information division.
