The method involves different surface finish retarders being overlapped or compressed into the mould prior to concrete casting. Immediately after mould removal, the surface is blasted with a controllable high pressure jet of water, and/or sand and/or air. In this way very different, sharply defined erosion depths are formed in the surface. Pref. different concrete mixtures are cast into the mould with different depths, time offsets, colour conditions.
