There are favorable and not-so-favorable characteristics inherent in all types of floor coverings. Every known resource within our industry is virtually powerless to protect any wood flooring product from the expansion caused by exposure to excessive moisture. Fortunately, in most cases, all the installation requires is a little time to dry and the product will return to the dimensions it had at the time of installation.
It is also vitally important to remember the role that Mother Nature played in developing our wood resources. Those resources - making use of sunlight, water and nutrients in the soil - followed nature's dictum to grow and expand.
