A thin, mortar used to seal thin cracks and joints. Grout is composed of cement, plaster, or lime, diluted with water and occasionally sand. Because of its thin consistency, grout can be forced into small confined spaces. In large scale projects, grout is used to seal geological faults and cracks in dams. It is also used to set the footings of steel columns in building construction. On a smaller scale, grout is used to consolidate crevices in masonry, to fill joints between floor tiles, and to finish walls and ceilings.
