Need advice on repair.
Controlled heat works well to remove moisture from small areas. If the area is reasonably small, something as simple as a dark frying pan inverted over a crack on a sunny day will result in a significant increase in the temperature of the surface immediately beneath it. Just be sure to raise the edge a bit at one point so that circulating air can carry away the moisture as the heat causes it to evaporate.
How long? Depends upon how large, how wet, how hot.
A single thickness from a black plastic bag would probably work, too.
