Hardwood floors will buckle if they are subjected to excess water.
Buckling also called cupping or crowning is the most extreme case of too much moisture.
If spilled water sits atop the flooring for too long or if moisture seeps into the wood from the subfloor.
Buckling can occur for a number of reasons.
Due to the porous nature of wood moisture can be easily absorbed into the material.
Whether there is too much weight on the wood flooring or exposure to moisture understanding why buckling occurs is the first step to fixing it.
Fortunately this is not a common occurrence.
Floor buckling is the most extreme reaction to moisture in a hardwood floor.
For example if a toilet overflows and the water reaches the hardwood hallway the hardwood planks swell with moisture.
Sometimes floors that appear dry to the naked eye can be soaked and the job might require industrial size fans and other equipment that removes water beneath the wood down into the subfloor.
Buckling occurs when the wood flooring actually pulls up from the subfloor lifting several inches in one or more places.
Because the wood needs to accommodate this excess moisture it moves upward and the expansion causes it to buckle.
