A retaining wall is a structure designed to hold back soil and prevent erosion on sloped land. It is commonly used in landscaping and construction to create level areas, manage water drainage, and enhance the aesthetic appeal of a property. Retaining walls can be made from various materials, including concrete, stone, and timber, and they come in different styles to suit different environments. These walls work by resisting the lateral pressure of the soil behind them, which can be caused by gravity, water, or other forces. Proper design and construction are essential to ensure stability and longevity, as poorly built retaining walls can fail, leading to soil movement and potential damage to surrounding structures or landscapes.
