Retaining Wall Types: Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope).
Retaining Wall Types
There are many different types of retaining walls, each with its own strengths and weaknesses. Here are some of the most common types:
- Gravity walls: These walls are made of solid materials, such as concrete or stone, and rely on their own weight to resist the forces of gravity. Gravity walls are typically the most stable type of retaining wall, but they can also be the most expensive.
- Cantilever walls: These walls are made of thin, sloping panels that are supported by a foundation at the bottom. Cantilever walls are less expensive than gravity walls, but they are also less stable.
- Counterfort walls: These walls are similar to cantilever walls, but they have vertical supports called counterforts that help to resist the forces of gravity. Counterfort walls are more stable than cantilever walls, but they are also more expensive.
- Retaining walls with gabions: Gabions are baskets made of wire mesh that are filled with rocks. Gabion walls are relatively inexpensive and easy to install, but they are not as stable as other types of retaining walls.
- Reinforced earth walls: These walls are made of soil that is held in place by a system of geotextiles and/or geogrids. Reinforced earth walls are relatively inexpensive and can be adapted to a variety of shapes and sizes.
The best type of retaining wall for a particular project will depend on the specific needs and requirements of the project. It is important to consult with a qualified engineer to determine the best type of retaining wall for your project.
Here are some additional things to consider when choosing a retaining wall:
- The height of the wall: Taller walls will require more structural support than shorter walls.
- The type of soil: Some soils are more prone to erosion than others. The type of soil will affect the type of retaining wall that is needed.
- The amount of water: If the area is prone to flooding, the retaining wall will need to be designed to withstand the force of the water.
- The budget: Retaining walls can range in price from a few hundred dollars to several thousand dollars. It is important to set a budget before choosing a retaining wall.
