A retaining wall is a structure designed to hold back soil and prevent erosion, particularly in sloped areas. Commonly made from materials like concrete, stone, or wood, these walls are essential in landscaping and construction. They come in various types, including gravity walls, which rely on their weight, and reinforced walls, which use additional support for stability.
The main purpose of a retaining wall is to create flat surfaces for building or landscaping while managing water drainage. Proper design is crucial to withstand the lateral pressure from the soil behind it. When built correctly, retaining walls stabilize landscapes and enhance property aesthetics.
