We are a company specializing in diving work and hydraulic engineering. We carry out all work in flowing and standing waters, technical facilities, contaminated waters, or other liquids that can only be performed with special equipment and special training. Our company was founded as a sole proprietorship in early 2006 by David Wiederkehr, a trained bricklayer and professional diver since 1984 with more than 30,000 hours underwater as a commercial diver in Swiss waters. He is a certified ADS diver to a working depth of over 360 meters and has been a diving instructor since 1988. Change of legal form from sole proprietorship to public limited company on February 8, 2008.

 

We know no limits

Our many years of experience and expertise make us competent partners in the planning and implementation of your projects. We prevent accidents and health risks through appropriate workplace facilities and clear regulations. David Wiederkehr has been diving accident-free for decades, and there have been no accidents involving employees since the company was founded in 2006. In our daily work, we care for the environment by using energy and resources sparingly. Our teams are at your service every day, summer and winter, with full enthusiasm. We would be delighted to count you among our satisfied customers.
