My basement is a full apartment and in the past 2 days water has randomly showed up on the tile and grout in one spot on the floor. It's not coming from the ceiling or fridge. I am baffled! Obviously underneath is foundation/cement/dirt/ground/normal under the houseness. Any help is appreciated!
Cement and grout are porous to water. The water table where you live has risen above the floor level of you basement and it is seeping in.
Yes, grout and cement is very porous. Water can seep through both of those materials. The best thing to do would be to waterproof your basement (if it's concrete) or seal the grout and tile.
