A retaining wall is an outdoor wall and used to keep the soil in place. It works in preventing the soil from sliding or eroding. A retaining wall is usually built on either side of an outdoor space to extend control to the soil at different levels. Retaining walls hold back the soil and prevent it from sliding away.
