A method is for generating a freeroom for a mast element in a ground. The method includes the steps: a) drilling a first annular recess into the ground, the first recess having: a first diameter; and a first depth; b) drilling a second annular recess in the ground, the second recess being arranged to receive the mast element, and the second recess: having a diameter which is smaller than the first diameter; having a second depth which is larger than the first depth; surrounding a first core of the ground; and being surrounded by the first recess; wherein there is, defined between the first recess and the second recess, a second core which can be removed to generate a freeroom.
