What Are the Design Considerations of Retaining Wall?
Of course, when designing your own retaining wall, you would want it to be perfect and durable. However, you must still consider other factors, and they should be suitable for your chosen retaining wall design.
Materials
When you are choosing your wall material, make sure to choose something that is long-lasting. High-quality retaining wall materials are hugely accessible everywhere, such as concrete modular units, brick veneers, poured concrete, flagstone rock, or vertical poles. You have to choose very carefully since you may have to use it for a lifetime.
Beauty
Make sure the structural design or design of your wall suits your house or construction; otherwise, it would seem off. However, make sure that you are just not focusing on the aesthetics or appearance of your wall as it may not function properly. In addition, your aesthetic treatment should not in any way build up hydrostatic pressure because sometimes homeowners tend to neglect drainage for the beauty of their walls.
Drainage structures
The drainage of water should be adequately addressed because it can result in a retaining wall failure if not. Each wall should have space for the water to freely move and drain away from the wall, and gravel backfill or drain pipes can be used to properly drain the water.
Foundation
As a homeowner, your responsibility is to ensure that your retaining wall’s base is sufficient to withstand any pressure and last long. Ensure that your retaining walls are built on structurally great material, which you must use gravel fill or earth that are leveled. The base thickness for dry-laid stone walls should be as high as the wall.
Security and safety
To build a secured and safe retaining wall, it must be stable against sliding. Another tip, every homeowner checks for wall overturning, so it would be recommended that you do the same. Overturning must be a minimum of 1.5. And then, the base of the wall must be safe in soil pressure, and the allowable soil bearing capacity should be greater than the maximum soil pressure.
Dimension and geometry
Your wall dimensions must be accurate and suitable to where you will build it; otherwise, it will fail. You should also consider the geometric proportions, including the base width, the thickness of the base, stem thickness at the bottom, the width of the toe, and stem thickness at the top. It differs depending on the type of wall you want; for example, for a cantilever retaining wall, the geometric proportions are:
- Base width: L=0.5H to 2/3H
- The thickness of base: D=0.10
- Stem thickness at the bottom: C=0.10H
- Width of the toe: B= 0.25L to 0.33L
- Stem thickness at the top: minimum of t=250mm
Type of wall
Choosing your retaining wall type will depend on your necessity, whether you decide to go for the structural wall made of concrete block or dry-laid.
Costs
If you install a wall using dry-laid materials, you must prepare a budget ranging from $20 to $35 per square foot. However, please note that the overall costs will differ depending on the materials you will be using, your preferred wall height, and other factors such as labor fees.
Cheap and Awesome Retaining Wall Design Ideas
A retaining wall does not only assist you in keeping the soil, but it can also add curb appeal to your home since it can be built as a natural, random-looking wall or super extra-looking wall.

Tiered Hedge
This looks fascinating as it is the combination of a tiered terrace and gabion wall. Instead of using a simple low retaining wall, a gabion wall is used. In addition, this adds more space for the hedges to grow.
Flowerbeds
Your retaining wall height is different because one side of the wall is higher than the other. And then, adding some brightly colored flowers will definitely finish and freshen up the look of your landscaped wall.
