Which structural problem necessitated the development of concrete vaulted ceilings within Roman fortifications adjacent to the sea?

💡 Explanation

When stone or wood fortifications were built near the sea, corrosion of wooden supports occurs because high humidity and salt spray accelerated material degradation. Therefore concrete vaulted ceilings were needed replacing wooden beams, rather than mitigating foundation issues, thermal issues or projectile impact which each demand unrelated construction methods.
