The answer to 'why is my retaining wall disease' is that your retaining wall may be deteriorating due to a variety of factors, such as poor drainage, soil erosion, or structural damage. Retaining walls are designed to hold back soil and prevent erosion, but over time they can become compromised and start to show signs of distress.
Some common symptoms of a diseased retaining wall include cracks, leaning, bulging, or even complete collapse. These issues can be caused by things like improper installation, lack of maintenance, or exposure to the elements. If left unaddressed, a deteriorating retaining wall can pose a serious safety hazard and may require costly repairs or even complete replacement.
