How are structures that are constantly in contact with water repaired or maintained? I imagine there has to be some sort of preparation or specific process for this?
In: Engineering
Concrete 100% submerged is significantly less susceptible to deterioration than concrete that goes through wet/dry cycles which would be in shallower depths. For shallow depth repair work, you can install temporary cofferdams around the work area to dewater the immediate area to complete the required work. Also divers can do many repairs, albeit slower/costlier in general.
