The provided content does not explicitly list a comprehensive set of symptoms for identifying seawall failure. However, it does highlight several conditions that indicate a seawall is experiencing stress or instability. Specifically, property owners should watch for differential movement caused by soil expansion and contraction, which can undermine seawall alignment. Additionally, the presence of structural cracks in concrete is noted as a failure indicator, which may require specific repair products for remediation. The content also mentions that leaning or bowing seawalls are key issues that often necessitate the installation of helical pier systems for stabilization.
