Hi Guys. Just been to look at a floor tiling job. 31m2 Entrance hall through to the kitchen,diner and utility needs tiling. The floor is concrete. On that is 10mm plywood. On that are tiles. these have been down for a few years. What I am trying to understand is these tiles have various cracks in them, and I don't think these were made by dropping things. When I tap a mallet on them it does sound a bit hollow.I would have thought the substrate was pretty solid. Could it be the addy wasn't laid properly.
Any dips in the tiles I would SLC. Would it be safe to tile on top of these or would you lift all the tiles and have a look at the ply.
