A cantilever wall is a type of retaining wall that is designed to hold back soil or other materials. It is constructed with a vertical stem and a horizontal base slab, which extends out from the wall. This design allows the wall to resist the lateral pressure exerted by the soil, making it effective for stabilizing slopes and preventing erosion. These walls are commonly used in various construction projects, such as roadways and landscaping. The cantilever design provides strength and stability, allowing the wall to support significant loads while minimizing the amount of material needed. Proper engineering is essential to ensure the wall's effectiveness and longevity.
