An apparatus and a method for monitoring a ratio of at least two mixed components use a sensor for detecting taggant particles in one of the components of the mixed material after installation. The sensor is positioned adjacent a surface of the installed mixture and is connected to a control device for displaying an indication of a mixture ratio of the components below the surface. The control device also generates a profile of the mixture ratio of the installed mixed material versus a distance from the surface.
