Is this warping tile tabletop fixable?
Second hand, but I’d love to be able to use the existing tiles/do less breaking and revamping, if you know what I mean. The tiles are all sloping towards the center of the table. I don’t think they’ve used grout (it feels like caulking, but I’m super new to the DIY world). The underside has one diagonal support. Pictures attached! Thanks so much in advance!
