Common Types and Characteristics of Retaining Wall

Constructing a retaining wall can be an interesting project for home improvement or landscape conservation. In hilly areas, these walls can contribute a lot by minimizing soil erosion, which has the potentiality to bring about a massive landslide. Homeowners should know about the basic types of retaining walls, their applications, and characteristics of retaining wall.

Common Types and Characteristics of Retaining Wall

1. Block Masonry

This wall should be less than 7 meters in height, and if you want to build a larger structure, we will suggest you build one with a height of 15 meters. The frontal slope should be in the range of 1:0.6 1:0.3, and the ratio should be vertical: horizontal.

Block masonry was built to prevent any kind of collapse at the foot level of the slope. This structure is mainly applicable to those places where the soil pressure is less and where the soil behind the structure is relatively dense. However, these structures are weaker because, in most cases, they can’t withstand the force of an earthquake.

2. Gravity

The height of this wall should be less than 5 meters, and the width of the base should be 0.6 times higher than the height. While building a gravity retaining wall for home improvement or landscape, make sure that you are careful of that base of the wall.

These walls support the soil pressure because of having deadweight. You can construct it on solid foundations as it has a great reaction, but it is not applicable in the pile foundations.

3. Cantilever

The height of this wall should range from 3 to 10 meters, and the width of the base should be 0.7 times greater than the height of that wall. This vertical wall can effectively resist the vertical load or soil pressure, and the net weight of the backfill over can also be utilized to provide adequate support to the pressure.

These structures are applicable for the pile foundations, and the precast concrete to construct these retaining walls is often used.

4. Counterfort

The height of this structure should be approximately 10 meters, and the width of the base should be 0.6 times higher than the net height of the structure. The vertical wall and the bottom slab is supported from three sides, and the counterfort type wall is better than the cantilever if you want to construct a higher retaining wall.

Sometimes the construction and backfilling become difficult, and it is mainly applicable for the pile foundations.

5. Leaning

In most cases, the wall should be 10 meters in height, and many homeowners build up to 15 meters. The ratio of the front slope should be 1:0.6 or 1:0.3 (vertical: horizontal). This wall supports the soil pressure with its deadweight, and it gets support by the soil either by the backfill or by the earth.

These structures are constructed for widening the roads in the hilly regions, and they are often built in places that have topographical and land constraints.

These are the major five types of retaining wall. A homeowner should study more about their designs, costs, pros, and cons to construct them for the landscape of home improvement.
