While all of this was going on, a couple of men in Ohio were changing our industry at that very moment. Paul Dinkel, a tile contractor with a vision, was determined to find a solution to the problem of ceramic tile failures when it was installed over sheetrock. He began experimenting with a glass mesh mortar unit, consisting of a lightweight concrete core covered on each side with a special fiberglass mesh. It would become known as Wonderboard. Together, with his partner Ted Clear, they revolutionized the tile industry with this product. Today, a wide range of products has been developed since Wonderboard's inception, and we refer to them today as backerboards.
