Diamond Grinding


Diamond grinding. Diamond grinding is the removal of hardened Portland cement concrete (PCC) through the use of closely-spaced, diamond saw blades mounted on a rotating drum. Diamond grinding is used for the removal of bumps or scallops that cause poor ride quality and to restore surface texture, improving overall friction.
