About IUT - International Underground and Tunnel Trade Fair

The IUT '11 is the only trade fair in the world to take place underground. Here in the Hagerbach Test Gallery (VSH) near Sargans in Switzerland, you can meet contacts from your target market face to face.

A special highlight of the IUT '11 will be the introduction of Brazil as a visitor to the fair. A prestigious delegation of tunnelling experts from the fifth largest country in the world, which is now one of the ten leading industrial nations, will be visiting the IUT and will be available for direct meetings. Just one more item on the agenda which shows that the IUT is more than just the average trade fair!
