Abstract: The present invention provides a method for forming a concrete surface having visual and tactile warning means for pedestrian traffic as well as for the users of wheeled conveyances produced by pouring a prepared concrete mixture into a concrete receiving form, floating the surface of the poured concrete, partially setting the concrete until a plastic state is achieved, covering the surface of the concrete with a release agent of a color different from the color of the concrete. Next, a stamp member is provided having a generally planar stamp surface interrupted by a pattern of indentations formed in the generally planar stamp surface. Additional colored release agent is applied to the stamp member and the stamp member is then positioned onto the concrete surface so that the release agent on the generally planar stamp surface contacts the release agent on the concrete surface.
