In terrain or mountain areas, when there is a change in the ground elevation which is pretty more than the angle of repose of the soil, at that time a structural design is constructed in order the retain the soil in its original place, which can resist the pressure of the soil. This structural design is named as ‘Retaining Walls’. So basically these walls are built in the terrain regions in order to prevent the soil related issues. The basement walls can be a good example of Retaining Walls. These walls are made up of various materials such as rocks, treated timbers, boulders, poured concrete, concrete blocks etc.
According to the construction mechanisms, there are different types of Retaining Walls:-
- Gravity walls – These walls are made up of concrete, stone or other heavy materials. These walls resist the pressure of the retained soil from behind. As the name indicates gravity, these walls depend on their mass. Therefore these walls are a bit short as compared to other walls. You can follow Seattle Retaining Walls
- Cantilevered walls – These walls have a shape of inverted T. These walls are built with cast-in-place concrete, or from a stem of steel-reinforced. These retaining walls can carry high loads. In comparison to the Gravity walls, less amount of material is used here. Cantilevered Retaining walls need concrete footings below the frost depth.
- Anchored walls – These are made to take high loads. These walls are constructed with the help of cables and sometimes the walls are anchored in the rock or soil.
- Sheet piling – These walls are made up of vinyl/wood planks or steel and are driven into the ground. These walls are constructed in tight spaces and soft soil. These walls can be expected to be taller.
Facts you should know about Retaining walls before planning for it:-
- These are mainly built to hold back the soil. But you can design these walls with colourful stones and boulders and can create a good space, where you can hang out with your close ones. This space can be a refreshment zone for you. But you need a good designer for this task.
- Never waste the space on which you will build the Retaining wall. You don’t need to make it in a straight path; you can add some creativity can make the wall go in some curves. Along those curves, you can plan your little garden.
- Before building the wall, please ensure with your Local Code for the permission regarding the size of the wall. As per your requirement, you can build smaller or larger walls. On an average, walls up to 4 ft height look good for a landscape view of the house.
- The most important thing is to create a solid base. Without a solid base it is difficult for the wall to retain the soil behind it. The base provides the main strength to the wall, so take
