The answer to 'why is my retaining wall' is that there are several common causes for issues with retaining walls, including poor construction, soil erosion, improper drainage, and damage from weather or landscaping. Symptoms may include cracks, leaning, bulging, or collapse of the wall. Solutions can range from minor repairs to complete wall replacement, depending on the severity of the problem.
If you notice any issues with your retaining wall, it's important to address them promptly. Small problems can quickly escalate and lead to more serious and costly damage. For minor cracks or minor tilting, you may be able to make DIY repairs, but for more significant structural issues, it's best to consult a professional landscaping or construction expert. They can assess the problem, determine the root cause, and recommend the appropriate solution to ensure the long-term stability and safety of your retaining wall.
