Embedded concrete marking

A method of creating an embedded concrete marking, the method comprising:

• identifying a location on the surface of a concrete slab where an embedded concrete marking is to be created;
• cutting a trench into the surface of the concrete slab at the identified location, the trench having a bottom surface and side walls, the bottom surface and side walls being a surface of the concrete slab;
• pouring a concrete mixture into the trench to a level where a float height of the concrete mixture is above the surface of the concrete, the concrete mixture being different when dry than the concrete into which the trench has been cut;
• letting the concrete mixture at least partially harden;
• and
• removing a portion of the hardened concrete mixture to create a top surface of the concrete mixture that will form an embedded concrete marking,
• wherein the concrete mixture in the trench bonds with the concrete slab at the bottom surface and side walls of the trench.
