In the process, the subsoil will be heated to over 100 degrees Celcius with heating elements in order to vaporize the CHCs. Numerous boreholes are required to install the heating elements. For the buildings in use, the boreholes are set at an angle and the structures are stabilized beforehand. However, three of them will be demolished in advance, according to the statement.
These buildings, which are in use, are monitored by tachymeters inside and outside. In a Denner store, a tachymeter is also used to measure its targets outside opening hours. In addition, a hose scale is used in a “sensitive” building.
