Cos.Idra was established in Padua in 1985 by Eng. Gabriele Graziani and quickly developed strong expertise in geotechnical works, particularly excavation in groundwater conditions.
In 1998, the company became a limited liability company and shifted its focus to small-diameter drilling, carrying out works such as micropiles and ground anchors. In the years that followed, ongoing investment in technology and specialist training allowed Cos.Idra to expand its capabilities, making jet grouting one of its core ground improvement techniques.
