Question I had 3-4 inches of salt water on my first floor from hurricane sandy. The flooring is 18 inch ceramic tiles that were installed on top of an old ceramic floor which is on cement slab. There are very few hollow sounding areas, most areas seem solid. There are spots where no grout remains. My contractor recommends ripping up the floor to avoid future loose tiles and "tiles popping.".I have read ceramic on slab would probably be okay, but this is ceramic on ceramic on slab. Any advice would be appreciated.
Answer Thank you for your question Ira,
I was expecting some questions along this line after so great of disaster up the Seaboard. Glad you have survived and are moving forward. If you had only a single layer of flooring I would just suggest that you steam clean the tile and grout and forget about it, but your Contractor's suspicion is valid, in light of the "tile on tile" scenario that you have. If this is part of an insurance claim then why not have it all removed and start from the original sub-strate and go again. This affords you the opportunity to move back down to original "finish" elevations and will improve transitions all over the house, and if your appliances were trashed as well then getting a new Dishwasher back under the countertop will be far easier. Unless the install of the second layer of tile was spot on there will be many avenues of intrusion where the salt water can get under and into the voids beneath all the standing tile by hydrostatic pressure from the weight of the water...not good, it could take months for the water to evaporate away from the spaces that you can't even see. If it were my home Ira I would demo it all and start again. Then choose a large format tile (18-20" size) and employ tight grout joints (1/8" no larger) and have a fresh updated space...ok? That's it Ira I hope this helps you with your problem at home, feel free to return anytime and I'm glad you are ok. God bless the USA...
