From 1957 to 1967, the ski resort growth created by Mr. Viladomat was incorporating state-of-the art facilities in Pas de la Casa.

On 22 November 1967, SAETDE (Societat Anònima d’Equipament Turístic-Esportiu de la Parròquia d’Emcamp) was incorporated and began to run two ski lifts, Escola and Font Negre.

From 1967 to 2004, Pas de la Casa's Grau Roig developed more new facilities, including detachable 6-seat chair lifts, Funicamp (a 6.137 metre cable car), restaurants, FIS Stadium etc., converting the ski resort into one of the biggest in the Pyrenees.

In October 2003, the new skiing domain of Grandvalira[2] became public as result of a commercial merger between Pas de la Casa-Grau Roig and Soldeu-el Tarter.

In 2005, Joan Viladomat founded Pas Grau International to promote, advise on, and manage, ski and mountain projects.
