What are the defects of caissons?

Caissons can experience several defects, including water infiltration, which can compromise structural integrity, and improper sealing that may lead to leaks or pressure loss. Additionally, issues such as corrosion of materials, especially in marine environments, can weaken the structure over time. Furthermore, inadequate design or construction can result in misalignment or instability, affecting the caisson's performance and safety. Regular inspection and maintenance are crucial to mitigating these defects.
