The primary purpose of retaining walls is to retain soil in place behind them. But the specific requirements will differ depending upon the intended use. For example, retaining walls can range from small discrete landscape stone blocks to massive soil retaining projects along a major highway. But the critical thing to note here is that even these massive structures need some essential planning before construction commences.
The size and type of soil are critical factors to consider when selecting a suitable retaining wall. Sorts of materials ranging from bare stone slabs to lush vegetation are used to construct such walls. Retaining wall pressure should be suitably calculated to ensure that the pressure of the walls doesn’t exceed the yield point. Moreover, it should also be high enough to withstand lateral loads.
In the case of concrete blocks, the height of the wall should be selected based upon the yield point. For example, a concrete wall with a yield point below 2 feet from the ground is considered low pressure. As such, you won’t have to use anchors for retaining walls of such height. However, if you want to use anchor bolts or ballast devices for higher heights, you can.
For concrete retaining walls, the concrete will be placed on either the top or bottom. In the case of flat roof systems, this choice would be obvious. But in the case of pitched or inclined roofs, it becomes imperative to consider the effect of pitched or sloped pressure and lateral pressure. Hence, you need to choose either the top or bottom of the pitched roof system. Anchor bolts may also be required for these structures.
Drainage systems are another critical aspect that requires attention. The drainage of a concrete cantilever retaining wall depends mainly upon the type of construction technique used. For example, you will not need any drain holes if you construct the wall using a plate and pin method. However, you can opt for drilled drain holes if you construct the wall using a traditional frame and footer construction.
Another critical factor that you must consider while constructing these retaining walls is the earth pressure. Earth pressure plays an essential role in the design of retaining walls. If your wall is constructed at a site with a high earth pressure, then you should try to install the wall in such a manner so that the soil stress is borne to the maximum extent. Reinforced retaining walls are constructed similarly.
Slopes are an integral part of most construction projects. And hence, you should also pay special attention to the levelling of the retaining walls along the slopes. Earth pressure will reduce the slope and hence the level of the wall. The best option to elevate the level of the wall is to use earth nailing or anchor roots. Anchor roots will help you to elevate the wall to the desired level.
Moreover, if you are constructing Outscape Constructions retaining walls Adelaide, then you should opt for reinforcement. Reinforcement is used primarily for retaining walls built-in soft soils like clay or slate. The additional burden will be provided by steel plates or by using concrete footers. However, the additional load will be distributed evenly across the structure. It is essential to use proper strategies like site ventilation and grading so that there are minimum chances of seepage into underground mines.
There are various ways in which you can construct high retaining walls. The most popular way to construct them is to make use of flatbed bolted constructions. However, if you do not want the structure to take external pressure, you can opt for galvanised steel rods and then finally be baked down. The concrete block forms a base for the entire structure and forms the support for all the required constructions like the walls, roof, floor and the like. If the structure is slightly slanted, then the concrete block can be placed on top of the soil nailing and then finally fixed.
