A retaining wall is a wall placed between two buildings or other structures to hold back the soil or surface water. A retaining wall may be made from a variety of materials, including concrete, earth, wood, and steel. Retaining walls can be used to prevent erosion and flooding in areas prone to heavy rainfall. They can also prevent damage to property from earthquakes.
Retaining walls are often constructed as part of a larger landscape project, such as building a patio or garden area. In some cases, they are installed specifically for this purpose. Retaining walls can also be used to create privacy areas, to organize gardens and even to create seating areas.
When considering the design and construction of a retaining wall, there are several factors that should be taken into account. These include factors such as the purpose of the wall, location, materials used and size.
