Finishing basement

Q: We are finishing our basement. It is cement and we are considering putting in a sub-floor, in-floor heating, and then installing cork flooring or tile. Which is the better option?

We’re leaning towards the cork; however, will the cork flooring be durable enough in the event of a septic tank backing up?

A: I think if there is any realistic possibility of a flood, you are better to go with tile.
