What is a “retaining wall”? It is a wall used to hold soil back on a slope so that it can move forward. Retaining walls can be considered rigid walls that are quite firm and hold soil backwards so that it can be held in place on the opposite side. They are very useful for sloping locations and are commonly used in commercial and residential areas.
You can build a retaining wall either above the ground or from the top if an existing structure. They can have a concrete face, or a mesh face, or both. A mesh wall is made with sloping joints. These joints are connected by low tension wires to metal ties or nails. The mesh walls do not need mortar to set as the mesh faces allow air and moisture to flow. Mortar is not recommended for residential purposes, as it adds stability and takes time to set.
A concrete wall’s basic design is to use three or more pieces. The end wall, or the first piece, is built against the slope using a long piece wood or concrete and a layer of rebar for backfill. This second wall is not used to support the earth work, but rather to strengthen the wall of the first piece. This is accomplished by adding horizontal wooden beams or fear to the second walls, which run parallel to the surface to be attached. These beams are reinforced using concrete blocks and are fixed by screws into the wooden floorboards below the second wall.
The actual shape of what is sometimes called a retaining wall is actually very much dependent upon the amount of slope on the site. Concretes are used for low slopes. Each concrete wall’s height will vary depending on the availability of natural fill material. The retaining wall is supported against the slope by a series vertical steel columns that apply lateral pressure. Concrete is cast into the shape at a construction site and then set into position, often by a crane, at the end of the slope where it is strongest and is capable of resisting the most violent effects of the wind.
A different type of wall is needed for steep slopes, where retaining walls must be built after the ground has settled. This is where excavation is necessary before the ground is leveled. The goal is to reach a point where the wall can be placed against the slope. The purpose of the wall is to divert runoff away from the house, not hold it in place. In this situation, the slope can be any type of incline, whether steep, gentle, or even a gradient that zigzags. This type of wall is best designed in regions where the soil behind the house is very soft, such as in the case of Colorado and the eastern states.
For retaining slopes, flat-rolled steel sheets are the most popular materials. In some cases, concrete wedges can also be used. Flat sheet piles are a popular choice in the United States. They offer many advantages over other options. They are very affordable at an average cost of twenty dollars per foot. Because of the low cost of materials, they can be made to order and are easy to put together. Flat sheet piles can be made to withstand any changes in the environment that could cause problems.
Concrete wedges are another option when it comes to creating retaining walls. Like flat sheet piles, these provide the same advantages as the flat option but are more economical and easier to install, due to their lower cost. While concrete wedges do require professional installation, they are far more durable and can stand up to changing climates better than other options. Concrete wedges are also more flexible in how the soil behind the structure is shaped, as they can be angled or sloped to the desired angle.
It is important to consider pressure when deciding what is appropriate for what is required in a retaining walls. There are two different classifications of pressure relief: dynamic pressure and tensile force. Pressure relief that is appropriate for a material’s tensile strength will be lower on the scale. This allows you to use smaller materials. Dynamic pressure is the force applied when a wall is being built. It is often expressed in pounds per square foot or as a percentage of the wall’s weight. For instance, if the wall is being constructed with fifty pounds of pressure per square foot, then this would indicate a cantilever retaining wall design which provides a higher level of safety and stability than those with less pressure.
