With the help of the Electric Impulse Technology, it is possible to remove concrete or mineral surfaces in existing building structures with low vibrations and emissions and to make openings by slotting and cutting. Very fast high-voltage impulses are generated and led to an electrode arrangement positioned on the material to be destroyed. A breakdown is generated in the material and thus the material is destroyed. On this basis, investigations into the removal of concrete as well as mineral structures are carried out and a machine concept for the use of the Electric Impulse Technology for operations in existing buildings is developed.
