Moisture in oak flooring

Oak Wood Floor

Oak wood flooring. Looks fantastic, feels solid to walk on and does not give a home to cat/dog fleas or house mites. Oak is heavy and hard and when laid down on top of a concrete floor you would think it should be pretty much rooted in place. Most of the time it does just sit under your feet just as solid as you would imagine. That is until the tiniest little thing called a water molecule invades the oak, not just a single one but, in fact, billions of them, known as moisture. When this happens the wood expands and the lovely solid oak floor becomes a springboard. We experienced this in our bedroom where the wooden boards had pushed against each other and we could see them buckling up. The curve was so great that it stopped a door opening! We had not spilled any water or had a flood, so what happened?
