One might think that the only way to know whether the grouted cells, bond beams, insulation, and other components of a Masonry Block Wall (CMU-Concrete Masonry Unit) are properly placed is to open the wall with a hammer or drill, where the grout or insulation is supposed to be and see if it is there. But this test is inadequate because the sample is much too small (often less than one ten-thousandth of a percent). Also, the tiny sample does not show where blockages (to the proper filling of insulation) and/or too much grout exists. The only other effective option is to X-ray the walls or tear them down -which are both extremely expensive.
