As a structure that is able to redirect water flow and prevent soil erosion, there is plenty to gain with it. Especially with the right material chosen for the structure. However, as durable as a retaining wall can be, it is not impervious to damage.

Whether the damage is the surface showing cracks or an issue with the base, there are different issues that your retaining wall can end up facing. Because of this, there will be a point that your retaining wall will need to be checked on for a possible rescue or full replacement. Determining which course of action would be best for your retaining wall can depend on a number of factors.

What Determines a Retaining Wall Repair or Replacement

Possible damages to a retaining wall can vary depending on the material used to construct it. For cases like a wood retaining wall, it can be something like fading in the wood or in a worst-case scenario, rotting. When it comes to determining whether a retaining wall still has room for repairs or requires a replacement, you will want to check on the following:

The Type of Material

As stated, there are a variety of different materials that a retaining wall can be made with and different types of damages that can be inflicted. Whether it be due to weather conditions or moisture in the soil, there are different signs to indicate certain levels of damage A common type of material used for retaining walls are concrete or stone and the number of cracks shown can help determine what state the material is in. For any material, however, if there is damage shown to the base that cannot be repaired, the only solution is a replacement.

Soil Condition

The soil is one of the most important features to check when it comes to retaining walls. It is the foundation of your retaining wall and its state can make or break your retaining wall. If the soil is soupy, then it’s likely that the retainer wall isn’t draining properly. Rather than escaping around the retainer wall, the water is being stored behind it. This can result in the retaining wall shifting or at worse cause it to erode. Depending on how much water is seeped into the soil, it can also end up putting too much pressure on your retaining wall and result in it bowing.

Loose Pieces, Crumbling, and Other Damages

While the state of certain materials can present certain signs for repair or replacement, there are also certain types of damage to a retaining wall that can signal maintenance for repair or when the structure is close to needing replacement pieces. An example of this would be the mortar between stones. The mortar between brick and stone tends to absorb water and eventually degrade over time. This can lead to pieces shifting or becoming loose or at worse, falling to damage and it is advised to replace the mortar with something stronger. Whatever kind of damage is seen or inspected with your retaining wall, there is always a point where damage can no longer be repaired.
