What Is A Retaining Wall And Where Are They Used?

A retaining wall is typically used to help level a slope or to prevent erosion. This means that this type of wall needs to be constructed to withstand the pressure of material, usually soil, on one side. 

Retaining walls can be part of a building, but they can also be used for landscaping purposes, such as to level out a very steep slope, or to provide protection to infrastructure like railway lines or roads. 

Within buildings, retaining walls are usually used to form the walls of basements or underground car parks. 

Are all retaining walls the same?

In short, no. There are several different types of retaining wall that can be used in different situations. For instance, a gravity wall is vertical on the side that withholds the soil, but sloped on its outer face. This makes the base of the wall thicker than the top. 

Similarly, a cantilever wall is also vertical on the soil-facing side and sloped on the outer side, but it also includes a base that juts inward from the vertical wall, providing extra stability to the structure. 

Then there are piling and anchored walls, both of which are vertical on both sides. The difference between them is that the anchored wall has an anchor providing extra support to the structure. 

What are retaining walls made from?

The best material to use for a retaining wall will depend on its specific purpose and its location. Commonly, however, such structures are made from concrete, stone or brick masonry. In many cases, reinforced concrete will be appropriate. 

If you are using concrete for the construction of a retaining wall, it’s essential to work closely with a reinforced concrete frame contractor who can ensure that the wall is built to last to the correct specifications. 

When deciding what material to use for your retaining wall, as well as ensuring it is durable enough, you also need to think about how visible it will be and whether you need to add other aesthetic elements to the structure.
