Retaining walls are structural elements that support soil, creating usable beds in steep terrain, and adding aesthetic features to your landscape. They may be freestanding or part of a larger construction project, and are necessary for slope-controlling projects. Larger retaining walls require planning permission, as they are likely to be subject to local authority regulations. However, if you’re planning to build a smaller, freestanding retaining wall, make sure that it’s structurally sound.

One type of retaining wall is the sheet pile. These are usually used in soft soil and tight spaces. They’re made of steel or aluminum sheets that support a mass, and can be either short or long. The height of a sheet pile retaining wall can be varied depending on the environment. A taller sheet pile wall will typically require a tie-back anchor, placed behind the face of the wall to withstand pressure from below. These walls are expensive to construct and tend to be less stable than a traditional gravity wall.

The height of your retaining wall is crucial, since the higher your wall is, the more load it can bear. You should plan to bury about one-eighth of the height of the wall. However, you shouldn’t exceed three feet if you’re building a three-foot-high wall. Ideally, you should bury the first course of blocks at least five inches below the level of the soil, and lay the gravel base over it. Make sure that the blocks are level, as a few uneven rows of blocks can have a significant impact on the finished wall alignment.

When building a retaining wall, it’s important to fill the space behind it with gravel or sand. This is important because dirt absorbs water and swells when saturated. This puts pressure on the back of the wall, and it can cause cracks and other damage. Adding gravel or sand behind a retaining wall also helps prevent soil from absorbing water. The weight of the gravel and sand prevents the wall from being damaged by cars.

Retaining walls prevent downhill erosion and stabilize the slope of your yard. In addition, they provide usable land, and are particularly useful if you live near a river or have a steep slope. The design of retaining walls is largely dependent on the slope of your property, but they do serve a useful purpose in the home environment. A level yard is easier to landscape and maintain, and they can protect your property’s foundation from erosion.

Among the many factors affecting the strength of retaining walls is their natural tendency. The earth’s lateral pressures are zero at the top of a wall, but increase proportionately as it descends. Without proper design, these forces can push a wall forward and cause it to collapse. Hydrostatic pressure, on the other hand, is caused by groundwater behind a wall. The total pressure can be up to one-third of its depth.
