Retaining walls play an important role in the overall stability and function of a landscape. Proper maintenance of retaining walls can ensure their longevity and prevent potential erosion. Maintaining a retaining wall requires regular inspection and cleaning, as well as proper installation techniques to ensure it is properly anchored and aligned. Maintenance also prevents or reduces the risk of potential failures in a retaining wall by assessing risk factors and designing maintenance schedules to counter them. Maintenance is done for a retaining wall that has already been constructed.

Factors to consider; Maintaining a retaining wall is important not only to keep the wall in good condition but also to protect homeowners and their property. Here are some factors to consider when maintaining your retaining wall:
Location: If the wall is in an area that receives a lot of wind or rain, it may need more maintenance than if it’s located in a less-vulnerable area. Material: The type of material used in the construction of the retaining wall also affects its maintenance. Retaining walls made with concrete or masonry is generally more difficult to repair and maintain than those made with natural materials like earth or sandstone. Height: The height of the retaining wall also plays a role in its maintenance. A retaining wall that is high will require more attention and maintenance because it is more unstable and possesses higher risk factors.
Maintenance types; They are two major categories of maintenance: preventative maintenance and corrective maintenance.
Preventative maintenance is a predetermined kind of maintenance done at intervals in order to lessen the chances of any future failures or degradation of the function of a property. It is further categorized into two; Predetermined and condition-based maintenance. Predetermined Maintenance is carried out at regular preset intervals without carrying out any prior condition assessments whereas condition-based maintenance is carried out based on parameter monitoring and subsequent actions.
Corrective maintenance is maintenance carried out after fault recognition and is intended to put the equipment into a state in which it can perform a required function. Corrective maintenance can either be immediate or deferred to a later date. Faults are usually identified through condition assessments. This involves an integration of life-cycle data and condition assessment information with other facilities management technology systems, such as computerized monitoring and management systems
Maintainance schedule; A maintenance schedule is a program containing a sequence of maintenance activities to be carried out over planned periods of time. The most effective kind of maintenance is proactive rather than reactive, that is, it should be planned rather than sitting back and waiting for failure, preferably scheduled to be carried out regularly. A maintenance schedule depends on a number of factors which include; maintenance objectives, budget, underlying conditions, and age among others.
Merits of maintenance:
Reduced risk of failure; Maintenance reduces the risks of failure in form of breakdown of the retaining wall. Maintenance involves inspection and assessment of risk factors like cracks or foundation settlement and designing measures to counter such risk factors to reduce the chances of failure. For instance, when a crack is noticed, measures to repair it are taken so that it doesn’t expand and eventually cause failure.
Increase wall’s life span; Maintenance increases the longevity of a retaining wall because it reduces the effects of wear, tears, and aging. Maintenance involves the replacement of some worn-out parts and elements thus aiming at returning the wall to a state as good as new. This increases the lifespan of the wall.
Maintains maximum efficiency; A faulty retaining wall is less efficient. If a retaining wall has a crack for instance, that compromises its drainage properties or load-bearing capacity. Proper maintenance ensures that a retaining wall is always at maximum capacity in terms of performance.
Safety; Retaining wall maintenance is a safety measure. A failure in a retaining wall poses health and safety risks. For example, a retaining wall that holds back earth on which a residential building is constructed. The collapse of such a wall could be catastrophic to the inhabitants of the building.
Downside; The major downside when it comes to the maintenance of a retaining wall is the cost incurred in planning and executing a maintenance schedule. Money has to be allocated for the professional services involved in inspection, planning, and execution. Money is also spent on purchasing equipment for maintenance.
In conclusion, retaining walls should be maintained to ensure the structure remains safe and sound. Properly maintaining a retaining wall can help prevent erosion and other problems down the line. Maintenance might be an activity that requires a hefty initial investment but it saves costs in the long run; costs of failure and repairs costs in recovery after retaining wall failure due to poor maintenance. Maintaining a retaining wall is a long-term investment in risk mitigation.
