Wall constructed to hold in place a mass of earth or prevent the erosion of an embankment. It may also be battered, with the face inclined toward the load it is bearing. The most basic type of reinforced retaining wall is the massive concrete gravity wall, which is prevented from falling over by the sheer weight and volume of its mass. A cantilever (L-shaped) retaining wall resists overturning by means of cantilever footings, spread footings (see foundation) shaped to resist overturning and sliding.
