Gravity walls are structures designed to retain soil and prevent erosion, relying on their own weight to resist the lateral pressure of the earth behind them. These walls are typically made from heavy materials like concrete, stone, or masonry, which provide the necessary mass to counteract the forces acting upon them. They are commonly used in landscaping, road construction, and various civil engineering projects. The design of gravity walls is straightforward, as they do not require additional support systems like anchors or reinforcements. Their effectiveness depends on factors such as height, material density, and the angle of the slope they are retaining. Proper drainage is also essential to prevent water buildup, which can increase pressure and lead to failure.
