Congoleum Kitchen Floor Buckling

Q: Hello, recently this week we had a leak from our dishwasher which caused some water to go between our congoleum floor and the wood sub-floor. Now as a result we have a thin crease in our congoleum floor about three feet long where it appears that the subfloor has buckled somewhat. It is not hugely noticeable other than a small crease and when you walk on it you can feel a bit of a rise. I guess I am wondering if this will subside over time or will this be a permanent rise in the subflooring? Any fix suggestions without having to pull the section of flooring?
Thanks.
A: Typically when something like this has occurred it will not go away. What you could try, since this moisture issue seems to be somewhat recent, is to try putting a small dehumidifier near the area of plywood which has been affected. This could remove some of the moisture and relieve a bit of the buckle, but the crease you are seeing will most likely remain and I doubt that the buckling will go entirely away. I would do your best to get the dehumidifier in from the under the plywood (along the joists) and make sure it is on a lower setting so it does not remove too much moisture from the rest of the subfloor.
Unfortunately, the only way to ensure that this buckle is gone would be to remove those pieces of plywood in the subfloor, replace them and then reinstall or replace the Congoleum tiles onto the new subfloor.
