Retaining wall is a structure built to withstand lateral i.e. horizontal pressure of soil or retain materials which are behind it. They are built to hold back filled-(soil) materials. Generally they are erected to prevent the soil sloping downward with erosion. They are raised when two adjacent soils are at different levels i.e. on slopes, hilly areas etc. They are considerably used on roads. Nowadays, they are extensively used in garden or landscaping while dealing with different levels which are either natural or manmade. Their main function is to sustain pressure and provide stability to the filled materials.
The retaining wall not only protects your landscaping and beautifies the surrounding, but it also contributes in increasing the value of your property. However, it is an engineering structure hence; it requires technical knowledge for proper design its execution. A homeowner who can identify the need for a retaining wall will obviously have to hire an experienced structural designer as well as a civil contractor to ensure that the wall is carefully and cautiously constructed.
According to ‘Francis D. K. Ching’ (Author of Building Construction Illustrated) When a desired change in ground elevation exceeds the angle of repose of the soil, a retaining wall becomes necessary to hold back the mass of earth on the uphill side of the grade change.
Apart from holding soil and creating a beautiful landscape, they also serve various other purposes. The benefit of retaining wall includes flood prevention, erosion control, and much more.
Let us understand in detail the benefits of retaining wall one-by-one:
The benefits of retaining wall are,
Benefit 1: Retaining Wall Prevents Damage to the Nearby Structures
If the structure or home is located on a lower platform compared to the surrounding land, there is a risk of soil on the higher elevated area collapsing or sliding down slowly on the building, thereby causing damage or structural problem to the home. By constructing a retaining wall, you can hold back this higher level ground and protect the existing structure or building.
Similarly, if your house is located at a higher platform than the adjoining ground which is comparatively at a lower level or it is on the bank of some natural water resource, the erosion of soil due to rain, floods or even earthquake will cause the soil to slide (sometimes suddenly). Such incidences may sometime lead to collapse of the house. This is because the foundation will get exposed and loosen the support of soil on which it stands. At times, we cannot prevent nature from running its course, but we can very well prepare for it. Thus, a well designed retaining wall will serve the purpose of protecting your house under such circumstances.
Benefit 2: Retaining Wall Helps to Resist Gravity Load
When your property is located in an area where the lateral pressure of a slope is exerting undue force at another area, you may consider the option of a retaining wall to balance and fight gravity so as to avoid landslides and erosion.
Benefit 3: Retaining Wall Prevents Erosion
Retaining wall averts soil erosion and this is the most important benefit of retaining wall. If you have sloped area on your property, you may be struggling with runoff problems. Raising a retaining wall is an excellent way of reducing erosion. By using a retaining wall near a border or slope, you provide leveled surfaces on inclined planes. Thus, soil is prevented from eroding on the downward incline. Retaining walls also secure the structure if they are just adjacent to it.

Benefit 4: Retaining Wall Controls Flooding
Heavy rains can sometimes cause flooding, leading to extensive property damage. Retaining walls constructed in flood-prone areas not only hold soil in place, but also prevent flooding/erosion during heavy downpours.
Benefit 5: Retaining Wall Helps in Diverting and Utilizing Rainwater
By implementing an innovative design in building a brick retaining wall, the rainwater which usually gets drained off can be diverted and utilized for better purposes in your home gardens and grass turf. You can use a retaining wall to direct rainwater into a collection system, which can later be used to water your garden and lawns.
Benefit 6: Retaining Wall Helps in Reshaping Slopes

Benefit 11: Retaining Wall Benefits to Prevent Sink Holes
Sinkholes may develop over a period of time in geographical areas where water slowly dissolves carbonate rock. This will ultimately create a hole under the surface area. The sinkholes can be small or large, depending on the speed of deterioration. These sinkholes are dangerous for the structure and it becomes difficult to fix once they start showing the problem. Thus, these retaining walls prevent sinkholes from damaging your landscape structure.
Benefit 12: Creates Usable Land
You may be familiar with older built neighbourhoods where homes are set up on a hill with a steep incline down to the street level.
