Abstract A method for the driving of steel profiles into a rock substratum is described, in which, before the driving, holes are drilled into the rock substratum, in which holes explosive charges are detonated. The explosive charge is so constructed and dimensioned that only the shock waves of the explosion act upon the rock, and not the combustion gases, so that the rock is only shattered in its internal structure but is not driven away. In the construction of a sheet pile wall, the holes are provided with explosive in mutually overlapping zones of differing depths, zones of the same depth being detonated at the same time and the charge in each hole being provided at top and bottom with a detonator each.
