One of the biggest misconceptions about cork flooring is that it absorbs water. Although cork isn’t 100% resistant to water and shouldn’t be exposed unnecessarily to liquids, it doesn’t absorb water. The truth is that cork absorbs very little water; that’s why it’s often used in the wine industry to seal bottles.   If you decide to install cork floors, they won’t fall apart into pieces when exposed to water, and they won’t swell.
