The purpose of constructing a retaining wall is to enhance drainage and prevent soil erosion. You should install one if you have a damp basement or foundation, see areas where water pools, or want to level a sloping yard. The potential for structural damage to your house or structure due to soil erosion and drainage concerns makes this an essential matter to address.

The good news is that retaining walls aren't that difficult or expensive to build, particularly if you use a professional. So, if you do end up needing one, the job shouldn't break the bank. How much a wall will cost, how long it will take to build, and what materials it is made of (concrete, wood, stone, etc.) are all factors to consider.
5 Reasons to Consider Installing a Retaining Wall
There can be several reasons to get a retaining wall. Some of these reasons may include:
Functional Slope
Retaining walls may make sloping terrain usable. In essence, the walls prevent dirt and water from flowing downhill by leveling the slope. Retaining walls may also facilitate pedestrian access to areas with slopes. A retaining wall levels the ground, making it easier to travel rather than navigate a steep slope.
Improved Drainage System
Retaining walls may also be used to redirect water flow in certain locations. This is particularly useful when a slope is close to a water feature. Be mindful, too, that constructing a wall for such an objective is subject to a plethora of local and state ordinances. Therefore, before you construct, make sure you conduct your study.
Erosion Prevention
As mentioned before, one of the primary functions of this wall style is to retain dirt. If the soil slopes downhill, erosion might occur in the region. A retaining wall is another option for controlling water runoff. The absence of a wall serving this function leaves the coastline vulnerable to erosion, which in turn causes the sea line to move. Be sure to check the local regulations on building permits before erecting any wall to stop erosion.
Design and Aesthetics
These landscape barriers are also often installed in homeowners' houses for aesthetic reasons. A building's landscaping might have extra elements added to it. Elevate the aesthetic value of any office structure with the addition of lighting and stunning stone.
More Space in Yards with a Slope
Land that is steeply sloping, whether up or down, cannot be used for anything. Cutting grass or cultivating any kind of plant becomes much more of a challenge on steeply sloping terrain. Weeds may spread rapidly on dry, sloping terrain.
If you want to grow trees, shrubs, and gardens but the slope is too steep, a retaining wall may assist. Stairs attached to the wall may also be used to reach outdoor spaces and front doors.

Common Types of Retaining Walls
Gravity Walls
The most basic kind of retaining wall, a gravity wall, uses its mass and geometry to counteract the lateral force of the ground behind it. Gravity walls, which may be constructed with little excavation and drainage, are usually constructed of stone, concrete, or masonry and have a base-widening trapezoidal or triangular cross-section.
The benefits of gravity walls aren't worth the risk of instability or overturning when dealing with tall walls or large loads. On top of that, they are space- and material-intensive, which raises costs and affects the environment. They also have the potential to disintegrate or fracture over time as a result of weathering or settling.
Sheet Pile Walls
In situations when the soil is soft or loose, a specialized kind of retaining wall called a sheet pile wall may be used either temporarily or permanently. These walls are built with small sheets of steel, wood, or plastic into the ground so that they interlock and create a continuous wall. Because of their versatility, sheet pile walls may be easily shaped and aligned to suit a variety of needs. They are also quick and easy to build and remove. In comparison to other retaining wall options, they are not only reusable but also cost-effective. Sheet pile walls, on the other hand, could run into trouble when installed or removed from soils that are too hard or rocky. Additionally, they could not be aesthetically pleasing or long-lasting due to corrosion, rot, or fading. Finally, they could buckle or leak when subjected to strong pressure or water flow. Therefore, they might need to provide more stability or drainage.
Cantilever Walls
Superior to traditional retaining walls, cantilever walls have a horizontal base that extends into the ground behind them and a vertical stem that supports the wall. This footing transfers soil pressure to the base, which in turn resists bending moments via the stem. The typical materials for these walls are steel or reinforced concrete, and their shapes might be rectangular or L-shaped. A cantilever wall's smaller cross-section and deeper base allow it to sustain taller walls and greater loads, and the reduced material and space needs of such a wall may lead to potential financial and environmental savings.
Nevertheless, they need a higher level of engineering and construction expertise compared to gravity walls. Additionally, they require greater excavation and drainage, which might heighten the likelihood of soil disturbance and groundwater problems. Also, cracking or collapse might be caused by earth movements or seismic stresses.
Key Factors to Consider Before Installing a Retaining Wall
Not everybody needs a retaining wall. Some people just jump into this decision and then regret it. Moreover, it can also cause you to choose the wrong type of retaining wall. Hence, making a sound decision is important. Asking yourself the following questions might help you decide whether a retaining wall is necessary.

Is soil erosion an issue in your landscape? When you notice this problem, the need for a retaining wall to prevent dirt from seeping into your yard becomes apparent.
Is there a soil fault line in the direction of your home? Having a retaining wall there can provide you peace of mind in the event of abrupt erosion, which may be triggered by an earthquake, even if this isn't causing you any problems at the moment.
Is water not draining properly from your yard? When it comes to drainage problems, retaining walls are the solution.
Are you after a gorgeous, functional, and low-maintenance landscape addition? Adding retaining walls to your property is an easy and low-maintenance technique to make it seem more attractive.
If you’re considering getting a retaining wall in your house or any other property, you should first contact a professional, take all the necessary information, and then make a decision.
