Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

There are cement admixtures that will harden despite being underwater. Normal cement will become too dispersed in an all water environment and won't harden at all. They can't just go to a cement plant and bring a batch of standard cement to fill this crack; they need a low w/c ratio (water/cement) mixture with a fast hardening agent, perhaps with large aggregate sizes so the cement will have something to 'catch' on in the crack.


Any idiot can face a crisis - it's day to day living that wears you out.
