In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured, and is commonly performed at small businesses and private homes. In 1977, the term concrete leveling was coined by Randall Greene in Cleveland, Ohio. He created the phrase to convey his company's ability to both raise and lower concrete to correct the insufficient grade of a slab.

Famous quotes containing the word concrete:
“Beauty, like all other qualities presented to human experience, is relative; and the definition of it becomes unmeaning and useless in proportion to its abstractness. To define beauty not in the most abstract, but in the most concrete terms possible, not to find a universal formula for it, but the formula which expresses most adequately this or that special manifestation of it, is the aim of the true student of aesthetics.”
—Walter Pater (1839–1894)
