Retaining walls, also called bank walls or slabs, is a sort of structural wall made to retain earth in a specific area. This is much like the retaining walls which are utilized to construct houses. The difference lies in how the role of retaining walls is to keep the earth from bases or other crucial locations. Retaining walls usually consist of lots of individual units, each having a specific aim or purpose. These are used in a wide variety of scenarios such as controlling erosion and also for a variety of functions.
Retaining walls can be made from different materials. Concrete block, wood and stone are some of the most well-known options. The type of material is dependent upon many factors like the amount of money available, the available space and the ecological problems. Different options are available to maintain the structural integrity of retaining walls. All these options must be carefully selected based on many different factors.
The strength of this structure and the quality of the soil are the primary determining factors. If these are solid then keeping walls will prove to be quite beneficial. When concrete is employed as the root coating that the durability is increased. The materials which are used for these walls must be extremely hard to withstand extreme weather conditions as well as pressure. The material selected for these structures also determines the amount of upkeep required. The higher the quality of substance and the better the reinforcement of those constructions, the more costly they tend to be.
If it comes to the selection of a substance for a retaining wall, we often must select between concrete and steel. These two options are effective in resisting any drive that’s applied to the wall. Each of these types of material has its advantages and disadvantages. Steelsly stronger than concrete but it is comparatively expensive also.
On the flip side, poured concrete supplies an extremely strong and durable material that does not require any extra support. In the event of a retaining wall, concrete supports are placed at particular intervals along the length of the wall socket. This permits the heavier items to be set in addition to the support with no chance of it becoming damaged. However, placed too low and also the burden of these objects can harm those supports. Poured concrete is also not too easy to install.
Proper retaining walls require excellent drainage. Good drainage ensures that water has been drained off in the construction without affecting its structural integrity. There are different ways by which good drainage can be achieved. If you have decided on a flat retaining wall, then it's possible to use the built-up eyebrow method wherein the elevation of this wall is increased upwards and also the width remains intact to have a gap left behind.
On the other hand, if you have selected the walls that need to be over four feet, then you need to use dug-in drainpipes. These drain pipes are installed within the walls. However, this requires a bigger hole and a lot more work than what is necessary for regular poured concrete. Another drawback of using this process is that after the pipes become wet, they tend to expand. To avert the pipes shrinking and getting uneven, you need to get them installed by professionals.
Apart from all of the above, another difficulty faced by most of the homeowners would be the slow pace where the retaining walls to maintain retaining the dirt behind them. As the ground gets compacted along the edges, it becomes more challenging for the walls to keep the soil without giving way. This is mainly due to the compact dirt behind the retaining wall. The soil pushes back and triggers a depression from the retaining wall. As a result, you need to dig holes to put the next layer of concrete.
