The answer to 'difference between retaining wall' is that a retaining wall is a structural wall built to hold back soil or other material on one side, while a freestanding wall is a decorative or boundary wall not meant to hold back material. Retaining walls are typically taller, thicker, and built with more durable materials like concrete, stone, or heavy-duty blocks to withstand the pressure of the soil. Freestanding walls are often shorter, thinner, and made of more decorative materials like brick, stone, or wood.
The key differences are that retaining walls serve a functional purpose to prevent erosion and soil movement, while freestanding walls are primarily aesthetic. Retaining walls require more engineering and construction expertise to build properly, while freestanding walls can often be installed as a DIY project. The cost of a retaining wall is also typically higher than a freestanding wall due to the additional materials and labor required.
