How does it work?
Phase 1, First, a hole of a precise diameter and depth is drilled into the material. The wedge set (one wedge and two counter wedges) is inserted into the drill-hole.
Phase 2, The wedge is driven forward under hydraulic pressure, forcing the counter wedges apart with a force of up to 450 tons. The material splits within seconds.
Phase 3, With enlarging counter wedges the split can be expanded to its maximum width. Reinforcing rods break or can be cut up with a suitable power tool.
