What is a Retaining Wall?
A retaining wall is a structure that holds back soil or rock from a roadway, sidewalk, parking lot, or other area. It is usually necessary to construct a retaining wall when the natural slope of the land is too steep and would otherwise erode or collapse. Retaining walls can be constructed from various materials, including wood, concrete, stone, and brick.
Types of Retaining Walls
Retaining walls are structures that are used to hold back soil or other materials from sliding downhill. They are commonly used in landscaping, construction, and civil engineering projects. There are many different types of retaining walls, each with its own advantages and disadvantages.
Gravity Retaining Walls
Gravity retaining walls are the simplest type of retaining wall. They rely on their own weight to resist the force of the soil behind them. Gravity walls are typically made of concrete, masonry, or stone. They are very strong and durable, but they can be expensive to build.
Counterfort walls
Counterfort walls are the most common type of gravity retaining wall. They have vertical panels that are supported by sloping buttresses that extend back from the wall face. This design distributes the weight of the wall more evenly, making it more stable.
Counterfort walls are typically used for walls that are more than 3 feet tall. They are also a good choice for walls that are in areas with a lot of seismic activity.
The buttresses on counterfort walls help to distribute the weight of the wall more evenly, making it more stable. This is especially important for tall walls, as the weight of the soil can create a lot of force on the wall. The buttresses also help to prevent the wall from overturning.
Crib walls
Crib walls are made of interlocking concrete or masonry units that are stacked to form a wall. They are relatively inexpensive to build, but they are not as strong as other types of gravity walls.
Crib walls are typically used for walls that are less than 3 feet tall. They are also a good choice for walls that are in areas with a lot of vegetation, as the plants can help to stabilize the wall.
Crib walls are made up of interlocking concrete or masonry units that are stacked to form a wall. The units are designed to fit together tightly, which helps to prevent the wall from collapsing. Crib walls are relatively inexpensive to build, but they are not as strong as other types of gravity walls.
Gabion walls
Gabion walls are made of wire baskets filled with rocks or other materials. They are very strong and durable, but they can be expensive to build.
Gabion walls are typically used for walls that are more than 3 feet tall. They are also a good choice for walls that are in areas with a lot of water, as the rocks help to drain the soil and prevent it from eroding.

Gabion walls are also very strong and durable, making them a good choice for walls in areas with a lot of water or seismic activity.
Cantilever Retaining Walls
Cantilever retaining walls are a more efficient type of retaining wall. They use their own weight and the force of the soil behind them to resist overturning. Cantilever walls are typically made of concrete or masonry. They are less expensive to build than gravity walls, but they are not as strong.
Cantilever walls
Cantilever walls are designed so that the weight of the wall is concentrated at the bottom. This creates a moment that resists overturning. The wall is also anchored into the ground with piles or piers.
Cantilever walls are typically used for walls that are up to 6 feet tall. They are also a good choice for walls that are in areas with a lot of vegetation, as the plants can help to stabilize the wall.
The cantilever design of these walls helps to distribute the weight of the wall more evenly, making it more stable. The walls are also anchored into the ground with piles or piers, which helps to prevent them from overturning.
Sheet pile walls
Sheet pile walls are made of steel sheets that are driven into the ground. They are very strong and can be used to hold back large amounts of soil. However, they can be expensive to install.
Sheet pile walls are typically used for temporary walls, such as those that are used for construction projects. They can also be used for permanent walls, but they are more expensive than other types of retaining walls.
Sheet pile walls are made of steel sheets that are driven into the ground. The sheets are connected together to form a wall. Sheet pile walls are very strong and can be used to hold back large amounts of soil. However, they can be expensive to install.
Embedded Retaining Walls
Embedded retaining walls are anchored into the ground with piles or piers. This type of retaining wall is very strong and can be used to hold back large amounts of soil. Embedded walls are typically made of concrete or steel. They are more expensive to build than gravity or cantilever walls, but they are very durable and can last for many years.
Embedded retaining walls are typically used for walls that are more than 6 feet tall. They are also a good choice for walls that are in areas with a lot of water, as the piles or piers help to anchor the wall in place.

This type of wall is very strong and can be used to hold back large amounts of soil. However, it is also more expensive to build than other types of retaining walls.
Reinforced Soil Retaining Walls
Reinforced soil retaining walls are made of a combination of soil and geogrids. The geogrids help to reinforce the soil and prevent it from sliding. Reinforced soil walls are very strong and can be used to hold back large amounts of soil. They are also relatively inexpensive to build.
Reinforced soil retaining walls are typically used for walls that are more than 6 feet tall. They are also a good choice for walls that are in areas with a lot of water, as the geogrids help to drain the soil and prevent it from eroding.
Reinforced soil retaining walls are made up of a series of panels that are filled with soil. The panels are connected together by geogrids, which help to distribute the load of the soil and prevent it from sliding. Reinforced soil walls are very strong and can be used to hold back large amounts of soil. They are also relatively inexpensive to build.
Choosing the Right Retaining Wall
The type of retaining wall that is best for a particular project will depend on the following factors:
- The height of the wall
- The amount of soil that needs to be retained
- The budget
- The aesthetic requirements
It is important to consult with a civil engineer or landscape architect to determine the best type of retaining wall for your project.
Here are some additional tips for choosing a retaining wall:
- Consider the height of the wall. The taller the wall, the more important it is to choose a type of wall that is stable and can withstand the lateral pressure of the soil.
- Consider the type of soil. Different types of soil have different properties, so it is important to choose a type of wall that is compatible with the soil type.
- Consider the budget. Retaining walls can range in price from a few hundred dollars to several thousand dollars. It is important to choose a type of wall that fits within your budget.
Advantages and Disadvantages of Different Types of Retaining Walls
There are many different types of retaining walls, each with its own advantages and disadvantages. Here is a brief overview of some of the most popular types:
- Concrete Retaining Walls: Concrete retaining walls are one of the most common types of retaining walls. They are strong and durable, and can be built to any size or shape. However, concrete walls can be expensive, and they require regular maintenance.
- Stone Retaining Walls: Stone retaining walls are very attractive and can add a lot of character to your landscape. However, they can be difficult to build, and they are not as strong as concrete walls.

Maintenance Tips for Retaining Walls
Retaining walls are a necessary but often overlooked element in any landscaping design. Not only do they serve an important function, but they can also be used to add aesthetic appeal to your property. With that being said, it’s important to keep your retaining wall in good condition so that it can continue to do its job and look its best. Here are some maintenance tips to help you keep your retaining wall in tip-top shape:
- Inspect your wall regularly for cracks, leaning, or other signs of damage. If you notice any of these issues, it’s important to have them repaired as soon as possible to avoid further damage.
- Keep plants and shrubs trimmed back from the base of the wall. This will help prevent root damage and ensure proper drainage around the wall.
- Make sure the drainage system around the wall is functioning properly. This includes downspouts, gutters, and drains. Clogged or damaged drainage systems can lead to water build-up which can cause problems for your retaining wall.
- address any erosion issues as soon as possible. Erosion can cause serious damage to a retaining wall if left unchecked. By taking care of erosion problems early on, you can avoid costly repairs down the road.
