The answer to 'difference between retaining wall' is that a retaining wall is a structure designed to hold back soil or other material on one side, while a fence is a structure used to enclose or divide an area. Retaining walls are typically made of concrete, stone, or other durable materials and are used to prevent erosion, support slopes, or create level areas for landscaping. Fences, on the other hand, are primarily used for security, privacy, or to mark property boundaries.
Retaining walls can be more expensive to install than fences, as they require more engineering and construction work. However, they can also add significant value to a property and provide long-term stability and functionality. Fences, while generally less expensive, may not offer the same level of structural support or erosion control as a retaining wall.
