Specifying Ground-Face Concrete Masonry Units
Ground-face concrete masonry units (CMU) provide architects and designers with an attractive architectural block texture. Ground-face CMU are produced by grinding the top 1/16 inch off the face of standard block with an abrasive cutting head to reveal the natural colors of the aggregates. This process provides a smooth textured unit available in a wide range of integral colors.
