"retaining wall"의 정의 및 의미

What is a "retaining wall"?

A retaining wall is a structure designed to hold back soil and prevent erosion on sloped terrain. These walls are often used in landscaping and construction to create level areas in hilly or uneven landscapes. Made from materials such as concrete, stone, or brick, retaining walls support the weight of the soil behind them, allowing for the safe use of land that would otherwise be difficult to build on. They can also enhance the appearance of outdoor spaces, providing decorative elements while effectively managing water drainage and soil stability.
