FLOOR MOISTURE MITIGATION

A finished floor is only as good as the sub-floor underneath.  When a floor fails, it is often the product of high levels of pH & moisture vapor emissions in a concrete sub-floor.  When this is the case, the result is an adverse affect in the bond of adhesives of new floor coverings.  Image Flooring understands this phenomenon and how to prevent or resolve excess moisture concerns.  Our understanding of flooring products and industry tolerances can insure your finished floor will not fail.
