Laminate flooring repair
If you are talking about the fake wood, floating type of laminate flooring that clicks together, you can't really repair it. This type of flooring does not handle moisture well and will bubble after being exposed to too much moisture. 

Depending on where the problem plank is, if you have any extra pieces from when the floor was installed, you may be able to take apart some of the planks to get to the bubbled one, replace the bubbled one with a new one and reinstall the removed pieces.
