Tips for planning a retaining wall


There are multiple factors to consider when planning a retaining wall. The location of the wall is as important as the aesthetics. However, the most important part is the base material used to construct and how to preserve the installation properly.


To ensure that the wall lasts for an extended tie, it must incorporate drainage, is of an appropriate height, and uses stabilization fabric. Any wall materials, locations, and size restrictions must be checked with local regulations.

Wall layout

The property where the retaining wall is installed must be identified as the first step in a retaining wall project. Use a garden hose laid on the grass at the determined location for a general layout. After you have the design, you must evaluate the area on several parameters. How are the site’s soils, and how much water passes through? This way, you will have a clear idea of the drainage needed behind the wall. Backfilling with three-quarter-inch clean stone is likely to suffice if you have sandy, well-drained soils. However, heavy clay soils that do not allow percolation and retain water may require a three-quarter-inch drainage stone and a perforated drainage pipe.

Wall height

After the layout is planned and complete, you need to figure out an appropriate height for the wall. Run a string line with a line level off the top of the slope; you can easily determine the size. Measure vertically from the bottom of the hill to the string line using a measuring tape. This way, you will get the measurement of the exposed wall height. Around 6-12 inches of buried walls must be added to this measurement, depending on the material used. You may, however, have to check with local codes to identify any restrictions on height that may be prevalent in your area.

Wall material

When it comes to the construction material used to build the retaining wall, you have many choices. Some options are natural wall stone and timbers, decorative concrete blocks, etc. However, your options are not limited to these. You can opt for decorative concrete blocks that come in various finishes, colors, textures, and shapes.

However, if you choose a decorative concrete block, you need to be sure that the blocks you use are rated for retaining. Some of these decorative blocks are so designed for freestanding walls only. Just as with decorative concrete blocks, natural wall stones to come in a variety of choices that are likely to suit just about anyone’s style and preference. Though the natural stone may come at a slightly higher cost, they are likely to perform much better and last much longer than other products in the market. The least expensive option still is timber when talking of construction materials for retaining walls. However it has become less popular over time.
