 CH,
The Swiss and many other European dignitaries celebrated the opening of the World's longest and deepest tunnel last week, the Gotthard Base Tunnel, after 17 years of construction. The tunnel beneath the Swiss Alps is 57-kilometers long (35-miles long) reaching a depth of 2,300 meters (7,545 feet, almost 1.5 miles). The tunnel will create a high-speed rail link between northern and southern Europe. Trains will travel the tunnel, which runs between the towns of Erstfeld in the north and Bodio in [...]

This project video seems a few years old, but it's relatively new on YouTube and it's a fantastic case study of the slick method of installing groundwater interception trenches using DeWind's remarkable one-pass trenching technology. Hill Air Force Base in Utah had been using jet fuel ignited on a mock aircraft to train firefighters. The jet fuel had leached into the soil and was reaching the shallow aquifer. The DeWind technology was used to install a drainage trench to intercept the [...]
