mine sits on wood flooring . had a few "spills " in the past and yes it did buckle a couple of planks . i hid them from the wife

. my problem at the time was i thought it would be a "great" idea to put some shower liner underneath the tank , wrong ! the water seeped under it and caused the buckling , which i didn't even know about until i switched tanks . now i have nothing between the wood floor and the tank so any water that does happen to spill i can wipe up and have a fan blow on it .
if your going to incorporate a fish tank into new home construction why not make the area underneath a basin with a drain . sort of like a stand up shower basin with a fish tank in the middle
