What happens if water gets under the tiles? – will there be a smell?

Although the unique design of R-Tile provides an extremely strong join, we do not claim that it is 100% waterproof. If large amounts of water are spilled and left on the floor, it is possible for some seepage to occur. However this water evaporates quickly as the interlocking system allows the floor to breathe. We have been manufacturing interlocking flooring systems for many years and have never had any instances where spillages have resulted in odours or substrate damage.
