Gravity walls are structures designed to hold back soil and prevent erosion. They rely on their own weight to resist the lateral pressure exerted by the earth behind them. Typically made from materials like concrete, stone, or masonry, these walls are often used in landscaping, road construction, and to stabilize slopes. The design of gravity walls is straightforward, as they do not require additional support systems. Their effectiveness depends on the wall's height, thickness, and the material used. Proper drainage is also essential to reduce water pressure behind the wall, ensuring its stability over time.
