You should seek those guarantees from the WY people. I personally don't see how the grout would hold up under those circumstances. The Avaire grout is flexible only to a small degree. I would also be a little concerned about point-impacts to the tile over a soft pad such as the one you are suggesting. Point-loads from furniture legs may also be a concern under those circumstances.
