(57) The invention relates to a method for fabricating a concrete slab (100) with an elongated channel (103) by using a digging tool (120) which removes unhardened concrete from a concrete slab by moving the digging tool in a digging direction (A) and rotating a blade assembly (124, 126) to scrape away a layer of unhardened concrete using the outer peripheral edges (124A, 126A) of the blade assembly and sideways pushing by using pushing sides (124B, 126B) of the blade assembly unhardened concrete towards the first end or the second end by rotating the blade assembly around an axis of rotation (122C). The blade arrangement moves the loosened unhardened concrete along an inner surface of a guide plate (130) into the direction of a collection chamber (160) of a discharge arrangement (170) by rotating the pushing sides (124B, 126B) around the axis of rotation.
