We have a simular problem and can't agree on how to fix it with the information that is available. We are ready to return all of the product ($2000 worth). The instructions say the floor can't be 1/4" difference over a 10' span. Our floor is wavey with an 1/8" between an 16" span. We have laid out 10 sq ft and the tiles flex over each low spot. Will this cause the grout to eventually break down and come loose and even cause the tiles to break? This is an old house.
