The answer to 'how does retaining wall work' is that a retaining wall is a structure designed to hold back soil or other material on an elevated slope. Retaining walls are used to create level areas on sloping terrain, prevent erosion, and provide support for landscaping features like gardens and walkways. They are typically made of concrete, stone, or interlocking blocks and are engineered to withstand the lateral pressure of the soil they are holding back.
Retaining walls work by distributing the weight of the soil evenly across the wall's surface. The wall's design and materials determine how much weight it can safely support. Taller walls or walls holding back heavier soil may require additional reinforcement like steel rods or geogrid fabric. Proper drainage is also essential to prevent water buildup behind the wall, which can compromise its stability.
